It calibrates every 4 hours, and when a check tank is installed (flag 6 set high by user) it is measured every 12 hours. The rain gauge should be fixed if it ever was wrong...old program gave the highest rainfall in the US...i question the quality of the precip data up to this date. I also tried to fine tune the pressure and temperature multipliers as Li7000 is a grumpy conversion to the 23x.

We are now measuring H2O vapor instead of scrubbing it. The new program stores the current H2O sample and H2O zero. The logger also has two thermocouples just measuring room temperature. The computer's hard drive died after this change and was "fixed" the following monday (050523). Its not really fixed but it appears to be working as long as i don't reboot the machine. Things appear to be working fine.

CO SENSOR - also calibrated CO sensor. i plumped the n2 and CO cylinders more permanently so that all you need to do is turn on the cylinders and press Run on CO sensor. Zeroing the CO sensor yielded a value of 0.4 ppm, changed from 245 to 239. Spanning dials started at 770 with a reading of 3.10 ppm. changed to 699 with reading of 3.00 ppm. Purged with zero air again until it was down to 0 ppm. then back to run. note, flag 8 was set high during all of this so that the data do not show the calibration. rechecked both zero and span and they returned to the appropriate values. repurged with zero. Something was wrong...disregard all data from beginning (~9:45) until 10:45 as I had the zero wrong. Data don't look right. I have read through the manual, the four inputs on the back can be used for automatic calibration. see page F-1 for instructions. Loaded new program onto logger (ASB_051221.dld). This program measures and calibrates CO automatically. I could not get the CO sensor to calibrate properly. I poked around on the inside of the instrument and found the pressure sensor tubing disconnected which made for darn near zero flow through the cell while sampling. Cal gases went through properly as they are pushed through...but sample gas is pulled through and it was not happening. So, after fixing that and leak checking most everything, I wired it and configured it to be controlled by the datalogger. It will now zero and span at midnight every day. This can easily be changed by the datalogger program. Gases are flushed through the system for five minutes. Each calibration value is stored in the data stream...see new column headings file. Updated RTDM files as well...deleted ozone graph, updated diagnostic figure to show CO cals. Flag 8 was set high at Cylinder Status: CO2 Std 1 - 051103_J4, 1300 psi, 345.30 ppm CO2 Std 2 - 050808_J21, 1200 psi, 386.14 ppm CO2 Std 3 - 051006_11, 550 psi, 421.54 ppm CO2 N2 Ref - 1700 psi CO N2 Zero - 850 psi CO Span - 1225 psi, 3.0 ppm 060103 - swapping std 3, it was at 200 psi.

NOTE the std 2 regulator does not ready zero, flag 8 high while swapping cylinders, the pump is able to draw cylinders to vacuum...so i am not deleting data. Cylinder Status CO2 std 1 - 051207_J42, 336.37 ppm, 2200 psi (NEW) CO2 std 2 - 051207_48, 401.76 ppm, 2200 psi (NEW) CO2 std 3 - 051208_J40, 503.99 ppm, 1600 psi (625 psi in 23 days = 27 psi per day = 59 days = empty by 060326) CO2 N2 Ref - 1000 psi CO N2 zero - 800 psi CO span - 1100 psi, 3.0 ppm 060222 - L1 clippard dying, flow rate down to 0.3 L/min (from 1 L/min). swapping it out. flag 8 high @ 1038. flow now 1 L/min. flag 8 high at 1047 Cylinder Status CO2 std 1 - 1500 psi CO2 std 2 - 1500 psi CO2 std 3 - 900 psi CO2 N2 Ref - 450 psi CO N2 Zero - 750 psi CO span - 1000 psi 060313 - swapped n2 reference, 060317 - new std 3 (060314_11 with 477.56 ppm). I also updated the program in an attempt to use less standard gas. Now the system samples every minute instead of every 5 minutes and the IRGA is set to a five second running average instead of a 20 second running average. The amount of time it takes to go from full std 3 to full zero is less than 10 seconds. This should be a great way to sample...I guess I will see. I also changed the daily data to be output to storage area 2 and thus to a different file. This way, I can separate out the daily data from the five minute data. I will still need to create different RTDM figures. The new program is called "ASB_060317.dld". Current cylinder status: CO2 std 1 - 051207_J42, 336.37ppm, 800 psi CO2 std 2 - 051207_48, 401.76ppm, 800 psi CO2 std 3 - 060314_11, 477.56ppm, 2300 psi CO2 N2 Ref - 2300 psi CO N2 ref - 750 psi CO span - 925 psi 060319 - Created new file organization scheem. Now data are posted to web based on year. "ASB_data.txt" now contains only current year data and only five minute data. New files were created for each years data (i.e. "ASB_data_2005.txt"). I also created "ASB_dailydata.txt" which contains ALL data that summarize a particular day. This file is for the yearly tab on the web page and will now run out for five years (1825 days). I need to do this at all sites. I created a new RTDM figure builder which just does the yearly tab. LoggerNet outputs the daily data as storage area 2 and to the new file. RTDM references this new file for its yearly tab. ********************** ASB Historical Data processing ***************************************** -------------------------From "ASB_CO2_data_01.xls"------------------------------------------------------------ Legend Differences from All Data_Raw.xls 1 added column headings 2 inserted columns to make each piece of the data set jive with the rest (I.e. if year was not present in one set of data but it was present in others, one column was inserted) 3 from beginning of data set to day 44 at 827, levels were 5 (for roof) and 7,8 (zero and span), those were changed to 1, 3, 4 to jive with rest of data set 4 deleted battery voltage data from beginning of data set to day 44 at 827 5 deleted seconds data from beginning of data set to day 44 at 827 6 some data sets have time stamps as HHMM, others have hour and minute as separate columns, columns were inserted to occupy space where hour and minute were, also inserted column for those data sets that did not have HHMM, and calculated HHMM based on hour and minute. 7 deleted 8 Feb 01, 1100 to 1230, see roof notebook 8 deleted 12 Feb 01, 1621 through 13 Feb 01, 1424, see roof notebook 9 deleted 20 Feb 01, 402 through 957, see roof notebook 10 deleted 28 Feb 01, 1552 through 1 Mar 01, 1022 11 deleted all outliers, zero, span, or roof from beginning to red line 12 deleted first few days of Summer data (29 June 01 to 2 July 01) because the zero was badÉsee notebook 13 deleted blank rows that were between individual .dat files from beginning to the red row and from the red to the yellow row 14 inserted columns from red row to yellow row to occupy space where 6262 data were located above red row 15 deleted outliers from red line to yellow line 16 formatting from yellow to blue was odd due to programming differences, data id arrays were 1, 2, 3, 4 depending on the type of data. I manipulated all this to one data stream by matching up the times. 17 span tank ran dry between yellow and blue, 18 formatted colors of cells to indicate specific irga used 19 pasted in li7000 and li 6262 data and deleted outliers within 20 pasted in li7000 only data which pretty much means that the data will be the same format from here on outÉpending the next "improvement" 21 deleted data from 19 nov to 20 nov due to closed stopcock and incomplete flushing of system 22 the zero goes bad on 26 nov 01É.the canister probably needs changing 23 it was not the canister, the relay board was not closing the roof inlet valve all the way when zeroing, problem fixed by 11 dec 01, NO ZERO USED IN CORRECTION 24 deleted all outliers from beginning to end (outliers are individual 5 minute measurements that donŐt jive with before and after data) ---------------------------------------------------------------------------------------------------------- 060321 - Started processing data to get all ASB data from the very beginning to a continuous set. Working with 2001 data here. From day 38 to day 82 of 2001, a Li6262 was measuring CO2. After day 82 of 2001 at 1207, the system went to a robot testing phase and was off for continuous measurements. Starting on day 183 of 2001, CO2 is measured by a gas hound. On day 205, CO2 is again measured by a 6262. Then on day 312 of 2001 at 1411, CO2 is measured with a Li7000. Created ASB_data_2001.txt and ASB_dailydata_2001.txt. The daily data for 2001 will ultimately end up in the master "ASB_dailydata.txt". ------------------------------------From "ASB_CO2_dat_02.xls"--------------------------------------------- Legend Comment Codes: 0) No known problems 1) M.P. column ran out I.e. hardened, caked. 2) Span gas ran out. 3) Reference gas ran out. 4) Other known 5) Other unknown Notes: Time: hhmm; Mountain Standard Time green denotes data from irga/datalogger, associated with CO2 measurements Span Tank: concentration of gas (ppm) inside the tank. Consult log books, etc. for tank name/lineage purple denotes data associated with H20 measurements Decimal day: uses this formula: julian day+int(hhmm/100)/24+(hhmm-100*int(hhmm/100))/1440; where int stands integer; example: int(6.35)=6 Corrected H2O: uses formula: measured H2O-measured zero H2O Corrected CO2: uses formula: (measured CO2-measured zero CO2)*(SPAN TANK/(measured span CO2-measured zero CO2)) *At points where the SPAN TANK ran out, data has been corrected using the last REAL span measurement and flagged with a 2. For example: 400.0=last measured span before tank ran out, the measured span CO2 would be replaced with this number (400.0) for all measurements with an empty span tank. The formula is used as listed above, but all results are flagged with a 2. ----------------------------------------------------------------------------------------------------------------- 060321 - Now I am working with 2002 data. I deleted everything with a comment greater than zero based on above comment codes. Created ASB_data_2002.txt and ASB_dailydata_2002.txt. 060323 - Working on 2003 data. Same comment codes as above. Minimal deletion of data...it looks like it have already been quality controlled. I deleted a few rows where comment 3 was. Created both ASB_data_2003.txt and ASB_dailydata_2003.txt. This is the year of the major overhaul problem. See notebook for specifics. Basically I screwed up the system and had to retro correct data between 4 April 2003 and 10 Sept 2003. I have also created ASB_data_2004.txt and ASB_dailydata_2004.txt and then pasted all daily data files into "ASB_dailydata.txt". This will be the yearly tab on the web. ******************************************************************************************************************************************** 060418 - CO instrument was reading "ERROR". I manually zeroed and spanned and now it appears to be working. The span cylinder may have been stuck on because it dropped by 125 psi in one month...which is a ton. Cylinder status: CO2 std 1 - 051207_J42, 336.37 ppm, 600 psi CO2 std 2 - 051207_48, 401.76 ppm, 750 psi CO2 std 3 - 060314_11, 477.56 ppm, 2100 psi CO2 N2 Ref - 1650 psi CO N2 ref - 700 psi CO span - 800 psi 060508 - power outage. deleted 715am - 1055am today day 128. 060510 - Particle filter installed on continuous system inlet. 060614 - swapped out atmospheric inlet clippard. it was dying. also deleted day 130 from ASB_dailydata.txt. this is the day i installed the particle filter and was breathing down the pipe. CO2 std 1 - 051207_J42, 336.37 ppm, 300 psi CO2 std 2 - 051207_48, 401.76 ppm, 400 psi CO2 std 3 - 060314_11, 477.56 ppm, 1800 psi CO2 N2 Ref - 500 psi CO N2 ref - 600 psi CO span - 600 psi 060705 - swapped n2 reference, flag 8 high at 10:07, swapped co2 std 1 and std 2. None of these cylinders were empty...but they were getting close. CO2 Std 1 - 060406_40, 360.04 ppm, 2000 psi CO2 std 2 - 060411_J38, 414.94 ppm, 2200 psi CO2 std 3 - 060314_11, 477.56 ppm, 1700 psi CO2 N2 Ref - 2200 psi CO N2 zero - 550 psi CO span - 575 psi Flag 8 low at 10:26 060810 - power outage around 9am to 930am. deleted data during that period. 061008 - swapped n2 ref. old one had 300 psi left. also swapped atm inlet clippard valve. i really need to move to a normally open system because this clippard is always on and they don't like that. std 1 - 1550 psi, 060406_40, 360.04 ppm std 2 - 1450 psi, 060411_J38, 414.94 ppm std 3 - 1150 psi, 060314_11, 477.56 ppm n2 ref - 2250 psi (new today) i have turned the CO instrument off because it reads only "Error". I have not had time to fix it. I emailed Terumi and Dr. Tyler. 070129 - N2 ref was empty...but data remained good due to solid cals. swapped with freshie. no data deleted. it started to be empty on 070127 at very end of day (see where zeros, std curve slope and intercept began to change relative to "normal" values. std 1 - 900 psi (6 psi per day, ~150 days left) std 2 - 700 psi (7 psi per day, ~100 days left) std 3 - 500 psi (6 psi per day, ~80 days left) n2 ref - (new today) (20 psi per day, ~110 days left) 113 days since last cylinder check. 070330 - swapped all three standards. none were empty. std 1 - 070112_J37, 2300 psi, 351.95 ppm std 2 - 070111_J23, 2100 psi, 401.67 ppm std 3 - 070113_J28, 2300 psi, 477.41 ppm n2 ref - 1100 psi 070418 - NEW PROGRAM (ASB_070418.dld) loaded on. This one measures Temperature and Relative humidity from an HMP50 located on the tripod on the roof. std 1 - 070112_J37, 2200 psi, 351.95 ppm std 2 - 070111_J23, 2100 psi, 401.67 ppm std 3 - 070113_J28, 2200 psi, 477.41 ppm n2 ref - 700 psi 070420 - reloaded new program...didn't have enough storage area 2 spots 070511 - modified weekly weather jpg to include new sensors 070516 - Leak found. Pump diaphram ruptured and system was taking in room air. Based on the zeros the pump diaphram ruptured on day 124 (May 4th) before 1400. CO2_sampl values changed from erroneous leaky value to 100 from 124 1300 to 136 1340. Pump repaired and good values start at 1540 on day 136. I also deleted all rows of data from asb_dailydata.txt from 124 to 135. 070517 - swapped n2 reference (new one has 1500 psi). 070706 - Power outage yesterday. Deleted data from day 186 1155 to day 187 1055. also deleted day 186 from daily data. 070723 - new n2 ref 071203 - N2 ref ran out 071202 5:40. Replaced N2 ref and changed co2_sampl values to 100ppm for 336,540 through 337,1340. 080307 - **** ENTIRE COMPUTER/SERVER IN ROOM 533 BACKED UP ON RETROSPECT. NOT JUST DATA, ENTIRE HARD DRIVE **** 080326 - Swapped tanks. old tanks: std 1 - 070112_j37 - 351.95ppm - 200psi std 2 - 070111_j23 - 401.67ppm - 200psi std 3 - 070113_j28 - 477.41ppm - 200psi new tanks: std1 - 080318_j55 - 324.86ppm - 2200psi std2 - 080314_j53 - 446.82ppm - 2200psi std3 - 080317_j54 - 477.56ppm - 2300psi New N2 ref tank between 1000-1400psi. Two readings from two seperate regulators. We'll see... 080408 - There was a power outage at ASB over weekend. No data for days 96 and 97. 080508 - N2 ran out on day 125. New N2 tank at 2200psi. Data deleted from day 125(1920) - 129(1210) 080903 - I, Steve Rowley have taken over as the technician for all profilers and robots. The N2 ref tank is empty and I have changed it out for a new one. It appears that the tank has been empty since mid July. For now I am only deleting the points that occured during my tank swap, namely, 2008,246,1625 - 2008,246,1805. 080930 - profiler is running smoothly, only a few erratic data points which I deleted. 2008,245,1050-2008,245,1205 and 2008,248,855-2008,248,1045 and 2008,253,820-2008,253,1100. 081031 - After much consideration I have determined that the data points between 2008,202 and 2008,246 cannot be recovered. These are the points that are about 10-15 ppm too high as a result of no reference gas being available from mid July to early September. Unfortunately, I must remove these data from the graphs, this will include every point between the above mentioned days for 5 minute data and daily data. 081106 - Power went out today, deleting points from 2008,311,1045 to 2008,311,1100. 081125 - problems occur with data transfer and data is lost from 2008,330,1055-1105. 081216 - N2 runs out. Installing new tank and removing all points between 2008,351,05 and 2008,351,1205. 090102 - The 115 VAC 60Hz pump is making a lot of noise. It sounds like a loose bearring. I am replacing the pump with a new one from inventory. I will repair the old one or send it back to KNF. No fixing of data is necessary. 090120 - the new pump had a crack in the head that covers the diaphragm. This was causing room air to mix with the samples and resulted in all concentrations being very stable. The pump was fixed on jan 16 and all data was erased between 2009,2,1210 and 2009,16,1410. 090128 - The pump is making a lot of noise during an atm measurement. concentrations are low. This looks like a clog. I will check the solenoid first. 090128 - The clog was in the inlet line on the roof. Most likely a chunk of ice, the Gellman filter fell of somehow so water must have accumulated and froze. A new filter has been installed things look good now. I am erasing all concentration data from 2009,27,1610 to 2009,28,1245. 090410 - nitrogen ran out last night. changing tank, and deleting data from 2009,99,2200 to 2009,100,930.
