Year of 2000
December 28, 2000
- 16:13 MST: San Clemente Island Data (SCI) has been added to the SRRL web site. Data is updated daily at 2:05 MST, the frequency may change in the future (more often). Data is currently available back to January 1, 2000, more data (back to July 1995) may be added in the future. -Afshin Andreas
- 08:21 MST: The BSRN Global and Diffuse PSPs were swapped on December 22 at 10:58 to 11:10 MST, the calibration factors in the datalogger were swapped today at 8:17 MST. See the BSRN Instrument history page for more information. -Afshin Andreas
- 19:57 MST: The EKO Sky Scanner stopped working today at 13:00MST, the cause is unknown at this time. -Afshin Andreas
- 10:32 MST: The TWC 500nm Photometer was fixed today at 9:46 MST. -Afshin Andreas
- 15:01 MST: The Direct TUVR was repaired today at 15:00 MST. -Afshin Andreas
- 10:29 MST: The BMS Solar calendars have been fixed. They now show all 3 components (global, direct, & diffuse). -Afshin Andreas
- 13:40 MST: The Direct TUVR is down, due to a broken signal cable. -Afshin Andreas
- 07:55 MST: The 500nm Photometer was disconnected this morning due to instrument problems. Noisy signal at night between midnight and sunrise, and high voltage output (up to 13.5 V) at approx 7:30 MST (almost every day), which caused the datalogger to put out missing values (-99999) due to overanging. -Afshin Andreas
- 14:57 MST: A PDF file (247 KB) has been created, which shows the physical mounting position for all BMS instruments on the deck, radiometer tower, and meteorological tower. -Afshin Andreas
- 15:59 MST: There is a problem with the CUVA1 Temp, which happened today at 11:00 MST. We are uncertain what the problem is at this time, however the CUVA1 Irradiance appears to be OK. -Afshin Andreas
- 08:34 MST: On Nov 27 @ 16:17 MST, the calculation for the PIRs was modified to include 3 calibration constants (instead of just 2). New constants for the Downwelling IR were entered into the datalogger (Upwelling was not changed). See the Instrument history page for more information. -Afshin Andreas
- 08:31 MST: On Nov 27 @ 15:57 MST, a new calibration factor for both the Global PSP (non-vent) and Diffuse 8-48 were entered into the datalogger program. The PSP was changed from 107.05 to 110.50 and the 8-48 was changed from 112.11 to 111.48, see the instrument history page for more information. -Afshin Andreas
- 08:21 MST: There is a bug in the WebCam32 software and/or the camera drivers, that is used for the SRRL Sky Cam, which causes the WebCam32 software to display the same image (even though the displayed time changes). This usually occurs after approx. 3-7 days of continuous running. This occured from Nov 14 at 9:00 MST to Nov 20 at 7:00 MST, the historical snapshots are all duplicates. The software was restarted today at 7:30 MST. -Afshin Andreas
- 08:14 MST: Campbell Scientific PC208W crashed on Nov 15 at 23:23 MST, data collection stopped on all stations. PC208W was restarted today at 7:30 MST. Data was only lost from the BSRN station from Nov 15 at 23:25 MST to Nov 18 at 17:20 MST. -Afshin Andreas
- 08:05 MST: For a temporary fix, the BMS calendar will display only the global PSP (instead of all 3 components). -Afshin Andreas
- 07:42 MST: The Solar Calendars are not currently working for the new BMS, likely do to the larger data size. -Afshin Andreas
- 10:26 MST: As of 11-01-2000, the new BMS is up and running. The improved system now has 40 irradiance measurements and 30 meteorological measurements, for a total of 70 measurements. The system now runs on two data loggers, a CR23X in the building taking data from the deck and the radiometer tower, and a CR10X at the meterological tower. Data is collected by direct RS-232 from the CR23X and by a 900 MHz wireless communication system from the CR10X. Data is collected from both loggers every minute, then merged to appear as one data stream. -Afshin Andreas
- 18:25 MST: Windows 2000 Server was installed on the web server (replacing Windows 2000 Professional), to allow more concurrent Internet connections to the web site. -Afshin Andreas

- 07:05 MST: The SRRL GPS Time page has been added to our server. The computer clocks at SRRL are maintained by a GPS system via satellite. This page displays a java clock of the current time (Mountain Standard Time) at SRRL accurate to within ±2 seconds. There is also instructions available to automatically adjust your PC time for your timezone using our Time Server. -Afshin Andreas
- 15:02 MST: Cloud Enhancement:
A good example of increased global irradiance due to clouds occurred on the afternoon of June 5, 2000. The reflective surfaces of the cumulous clouds that developed over the Rocky Mountains resulted in the increase of global horizontal by about 70 Watts per square meter compared to the expected clear sky value of about 900 Watts per square meter at 14:45 MST. A look at the time-series data for this and other global irradiance measurements (e.g., 2-axis global, or 40 degree south-tilt) also show the cloud enhancement effects. Hourly Sky Cam images for the day confirm the rapid change from clear sky conditions before 14:00 MST to cumulous clouds to the west at 15:00 MST. -Tom Stoffel
