TSR-1 Global Horizontal W/m2 08/28/2009 - 590, 591, 592 N/A
Global Horizontal Irradiance measured by a thermopile pyranometer, with a spectral response from 300 to 2800 nm.
TSR-1 Diffuse Horizontal W/m2 08/28/2009 - 590, 591, 592 N/A
Diffuse Horizontal Irradiance measured by the above pyranometer, when band rotates and blocks the sun.
(calc) Direct Normal W/m2 08/28/2009 - - N/A
Calculated using Global and Diffuse measurement.
(calc) Zenith Angle o 08/28/2009 - - -
Solar zenith angle calculated by TSR data acquisition system.
- TSR Temperature oC 08/28/2009 - 590, 591, 592 -
Temperature of TSR head unit, which is maintained at 45oC.
- TSR Box Temperature oC 08/28/2009 - - -
Temperature of TSR data acquisition system enclosure, which is located outside.
- TSR Heater Voltage VDC 08/28/2009 - 590, 591, 592 -
Voltage applied to TSR heaters.
Notes:
  • Data Sample rate is every 15 seconds with 1-minute average output, prior to 16-SEPT-2009 it was 60 second samples (no averaging).
  • Data was collected by YESDAS, then converted from Spreadsheet UTC time to Mountain Standard Time (MST), then the data sets from the 3 instruments are merged for MIDC.
  • The TSR cleaning maintenance history is available.
