-Afshin Andreas - 10:31 MST: Due to data logger clock corruption, SMUD Anatolia data from Dec 14 through 16, 2012 has been removed from MIDC until further notice. -Afshin Andreas
- 10:03 MST: SRRL BMS historical preset equations used from 1985 to 2003 were updated to use the correct input variables, which were never updated for a revised preset configuration that was made several years after. -Afshin Andreas
- 10:46 MST: The preset equations which are available for some measurement stations (which are calculated on the fly from raw data), are now defined for the user. Simply click the word "Preset" next to the radio button that appears on the download page for an applicable station. -Afshin Andreas
- 11:19 MST: At 9:40 MST today the SRRL BMS data stream was upgraded to version 12.0. All historical data since June 1, 2012 was converted to this format. The following changes occured:
- Add raw mV signal output for all pyranometers which have a net infrared thermal correction applied
- Removal of two Global PSP readings with no zenith angle correction
- Removal of Diffuse PSP with no net infrared correction
- Add Direct Quantum LI-190 sensor
- Rename CNR1 calculated fields to K&Z and use Downwelling CG4 and CM22 instruments instead of Downlwelling CG3 and CM3 for Albedo, Atmos Net Infrared, and Net Radiation.
- Restructure raw data field order to support future instrument re-location and new radiometer tower.
- 08:50 MST: No new SRRL PWV processed data has appeared on the UCAR website since November 19, 2012 at 13:45 MST. However, Trimble at SRRL is still collecting raw data, problem is unknown at this time.
