The pyrgeometer intercomparison can be considered to have officially started at 12:15 (1715 Z) today. Yesterday, Tony mounted fans on all housings. Today, I just connected the radiometers which were recalibrated (after their swim in oil) and received here last night. (It was necessary to reposition both radiometers on their 8-hole base plates to fit the housings.) I also just leveled all of the Schwartz's (not knowing if this had been done already) using the old digital level. Obviously, I didn't have a good reference surface, but I still think that I got them to within 0.1 degree. (They all sight to the horizon similarly.) 30: Radiation, Site , Mon 27-Sep-1999 11:55:30 CDT, releveled radiometers I just used the small bubble level to check the levels. Most looked okay, though I adjusted the western 2 and the eastern 1 a bit. 33: Radiation, Site , Tue 28-Sep-1999 18:08:51 CDT, playing with rad biases from IC Here is a first cut at adjusting biases on Rpile from the radiometers based on data from the interval "99 Sep 25 17:00",lenhr=31,stns=0: Rpile.in.a.boom Rpile.in.b.boom Rpile.in.s01 Rpile.in.s02 Rpile.out.a.boom 0 0.5 -1.2 bad 0.7 Rpile.out.b.boom Rpile.out.s01 Rpile.out.s02 Rpile.out.s03 Rpile.out.s05 0.4 -1 bad 0.2 10 36: Radiation, Site stn3, Wed 29-Sep-1999 15:58:52 CDT, Tsfc replaced on PAM-3 Everest IRT Swapped: Sensor 3577-4 removed; sensor 3577-2 installed After the thunder/rain storm 2 nights ago the old sensor was reading 100 deg-C. 41: Radiation, Site , Fri 01-Oct-1999 23:04:50 CDT, cleaned domes Just cleaned domes on all pygs in the IC array. They all were somewhat dirty. Also checked levels and all were good. 47: Radiation, Site , Tue 05-Oct-1999 19:38:10 CDT, moved rads out of IC Installed 48m boom about 1300 today - leveled to within 0.003 deg. The pull rope is tight! Also, don't trip over the CR10 box on the floor at 49 m. Mounted radiometers at stns 5, 2, and 1 (in that order), but not reporting yet. stn5 is down waiting for a power cable/solar power move and baud rate change. stn1 is waiting for a baud rate change stn2 is waiting for a new battery! stn3 is waiting for the whole rad stand to be moved. 49: Radiation, Site , Wed 06-Oct-1999 17:07:04 CDT, radiometer work Stuff done today: stn1: changed CR10 baud rate to 1200. Commands are: *0 7H *1 A (until step 62) 51 (overwrites 52) *0 (this can be done through EVE by typing: entersys stop talk (port 4, rate 9600, etc.) start Rnet is Q97034 stn2: moved solar panels; hooked up battery swiped from stn5; mounted Rnet with 2 screws (only had one before); leveled Rnet; added connector to bare wires from Rnet so it could plug in; changed baud rate to 1200. Rnet is labeled "station2" stn3: moved solar panels; moved rad stand from IC array; leveled and oriented stand; mounted Rnet from box labeled "station3", but with a label of "station1"! Found that fan cable wires were color-coded backwards, so rebuilt this cable (red negative, black positive); changed baud rate to 1200. stn5: stole battery from main station to power radiometers at stn2; removed wrong DC power cable; attached good DC power cable; cut cable ties; changed baud rate to 1200. Rnet is Q97035. All rad stand solar panels are now located about 4m to the NE of the CR10 box, with the CR10 on the East side of the rad stand. 53: Radiation, Site , Fri 08-Oct-1999 08:52:04 CDT, Rnet cal factors Rnet calibrations from REBS 8/17/99 calibration are: Positive Negative (Zero Wind CF in W/m2 mV) 94196 9.25 11.44 97035 9.28 11.54 stn5 (stn5 is using these values) 94197 9.07 11.25 (stn2 is using these values) 91096 8.54 10.59 94125 8.65 10.75 (stn3 is using these values) 97034 9.31 11.39 stn1 (stn1 is using these values) 56: Radiation, Site stn1, Fri 08-Oct-1999 12:32:09 CDT, Corrections for radiometer deployment errors I inventoried the surface radiometers to investigate the cause for some anomolous long wave data: Station Rnet Pyg.in Pyg.out Psp.in Psp.out 1 97034 29260 26416 2 94197 31977 31981 940181 940187 3 94125 31975 5 97035 31979 This showed that the radiometer arrays on stations 1 and 2 were interchanged when deploying them at the end of the intercomparison period. This morning (Oct 8) we entered into the CR10 loggers at stations 1 and 2 the coefficients corresponding to the radiometers mounted there. WARNING WARNING WARNING WARNING WARNING WARNING Be aware that the labeling of the radiometers at stations 1 and 2 is different for the intercomparison than it is after the radiometers were deployed at the various PAM stations. WARNING WARNING WARNING WARNING WARNING WARNING The coefficients for the PSPs at station 2 were entered around 9:30 am local time. The coefficients for the PYGs at station 1 were entered around 10:55 am local time. The coefficients for the PYGs at station 2 were entered around 11:10 am local time. At that time we found that the signal cables for the two PSPs were interchanged and this was corrected at the CR10. At station 5 we found a small error in the third coefficient of the Tcase.pyg.out calibration. The data sheet lists a coefficient of -6.90295 and the CR10 has a coefficient of -6.9229. It was decided to leave this coefficient as we found it, since this value was used during the field intercomparison of the radiometers. 135: Radiation, Site stn2, Mon 18-Oct-1999 11:59:54 CDT, PYG.OUT at station 2 questioned and fixed (?) The pyg.out pile was bad so I went out to look at it. According to Tom, this problem has happened before. The voltage going to the multiplexer board was varying quite a bit. I played with the connector inside the Campbell which resulted in a good signal. The cables had been reversed from a previous test so I switched them back to the correct configuration. Will need to monitor to see if fix works. If so, we will need to flag this Campbell box for repairs. 136: Radiation, Site tower, Mon 18-Oct-1999 16:38:11 CDT, Cleaned radiometers at 50m and PAM stations We retracted the 50m radiometers and cleaned them, beginning at 1500 CDT, Oct 18. They were cleaned with "de-mineralized" water and kimwipes. The radiometers were returned to their outboard position at 1615 CDT (after unfouling the hauling line with the loooon green hook). The domes of the surface radiation sensors were also cleaned after finishing the tower radiometers. 161: Radiation, Site stn2, Fri 22-Oct-1999 13:33:22 CDT, Cleaning radiometers At 11:15 the domes of the radiometers at station 1 were cleaned At ~13:00 the domes of the radiometers at stations 2, 3, and 5 were cleaned. There were traces of brownish grey dust, especially on station 1 domes All net radiometers were cleaned. All fans were running. The fan at station 3 was noisy. 169: Radiation, Site , Sun 24-Oct-1999 12:59:33 CDT, Cleaned radiometer domes Between 1230 and 1300 the domes of the radiometers at stns, 1,2,5 and 3 were cleaned 174: Radiation, Site , Tue 26-Oct-1999 13:06:08 CDT, Cleaning domes Between 1030 and 1115 the radiometer domes and the net radiometers were cleaned at Stations 1,3, 5 and 2. Photographs of the ground surfaces under the radiometers were taken. 177: Radiation, Site , Tue 26-Oct-1999 20:02:28 CDT, Cleaned 50 m radiometer domes At ~ 1530 on 26 October the 50 m trolley was pulled in and the four radiometers' domes were cleaned with water wetted tissue. There was indication of brown dirt on the domes. 186: Radiation, Site , Thu 28-Oct-1999 12:28:53 CDT, Cleaned radiometer domes Between 1030 and 1100 the radiometer domes were cleaned at Stations 1, 2, 5 and 3. All the fans were operating smoothly 195: Radiation, Site base, Fri 19-Nov-1999 16:17:42 MST, Baud rates of rad data loggers NOTE! The campbell loggers on the PAM stations transmit at 1200 baud. They were set this way in the field at CASES99 after the intercomparison period. 198: Radiation, Site , Tue 30-Nov-1999 15:45:48 MST, pyrgeometer coefficients lwdiv 199: Radiation, Site , Wed 01-Dec-1999 09:15:32 MST, Pyrgeoemter Campbell coefficients These are the coefficients determined from the oil-bath temp calibration of the pyrgeoemters, prior to the CASES99 deployment. These coefficients were used during the pre-CASES99 intercomparison in the field and during the deployment. They are also to be used for the post-CASES99 intercomparison on the roof at the Foothills Lab.

This seems to have cured the problem. At ~1700 I removed all the snow from the radiometers and cleaned the domes. 201: Radiation, Site , Wed 08-Dec-1999 10:34:02 MST, Snow cover on pyrgs o Previous - Index At 1030 Wed 8 Dec''99 I temporarilly depowered the fans to allow a full snow cover over all the pyrgs. It started to snow in the nightime and although the fans had kept the dome clear snow had built up on the shield so that the snow formed an annulus higher than the top of the domes. Snow is forecast to continue for the next 24 hours The extra snow did not occur, the existing snow on the domes evaporated. On 9 Dec at 11-30 I restarted the fans and cleaned the domes.
