SolarSIM-D2+ SolarSIM-D2+ Channels 1 through 6 mV 09/01/2016 - 107 see database
Raw signal from each narrow band direct normal spectral channel. Each channel uses a hard coated 10nm bandpass filter at the following wavelengths: 425, 500, 610, 780, 880, and 940 nm.
SolarSIM-D2+ SolarSIM-D2+ Internal Temperature and Relative Humidity oC
09/01/2016 - - -
The SolarSIM-D2+ internal temperature and relative humdity. The SolarSIM-D2+ is a sealed instrument with desicant, so the RH should be below 20% at all times.
SolarSIM-D2+ Air Temperature and Station Pressure oC
09/01/2016 - - -
Air Temperature and Station Pressure as measured by SolarSIM-D2+.
- Time Zone hr 09/01/2016 - - -
Time zone is a required input in raw data file for the spectral model (SolarSG software).
- Logger Battery Voltage V 09/01/2016 - - -
CR800 battery voltage; logger battery is charged by AC adapter.
- Logger Panel Temperature oC 09/01/2016 - - -
CR800 panel temperature; logger is located in SRRL data lab.
- Zenith Angle V 09/06/2016 - - -
Zenith Angle as calculated by CR800 Solar Position function. Data from the SolarSIM-D2+ is only collected during daylight hours (Z<90).
SolarSG Direct Normal, Ozone, Water Vapor, AOD, Zenith Angle (various) 06/06/2017 - - -
Broadband Direct Normal Irradiance, Ozone, Water Vapor, 500nm Aerosol Optical Depth (AOD), and Solar Zenith Angle as calculated by the SolarSG spectral model during MIDC post processing. As of 13:31 MST on 22-SEP-2017 these values are now generated using SolarSG v3.1. As of 07:23:20 MST on 26-AUG-2020 these values are now generated using SolarSG v4.3 and includes AOD at 368,412,675,862,and 1024nm. As of 08:17:20 MST on 21-JUN-2021 these values are now generated using SolarSG v4.42.
