LI-200 Global Horizontal W/m2 02/03/2009 08/24/2013 PY61283 -10.44 W/m2/µA
08/26/2013 - PY29660 -10.95 W/m2/µA
Measured using a LICOR LI-200 Pyranometer mounted on an Irradiance Inc. Rotating Shadowband Radiometer (RSR). RSR mounted on the ground and the LI-200 sensor height is approx. 7 feet above ground level. The uncorrected value is for testing and troubleshooting purposes only. Voltage is measured across a 100 Ohm precision resistor in parallel to sensor output.
LI-200 Diffuse Horizontal W/m2 02/03/2009 08/24/2013 PY61283 -10.44 W/m2/µA
08/26/2013 - PY29660 -10.95 W/m2/µA
Measured using the above LI-200, when RSR band rotates every 30-seconds and blocks the sun. The uncorrected value is for testing and troubleshooting purposes only. Voltage is measured across a 100 Ohm precision resistor in parallel to sensor output.
(calc) Direct Normal W/m2 02/03/2009 08/26/2013 - FD = 1.03378
08/26/2013 - - FD = 1.0
Calculated using Global and Diffuse measurement. The uncorrected value is for testing and troubleshooting purposes only.
LI-200 Global Horizontal (secondary) W/m2 02/25/2009 08/24/2013 PY61743 -10.36 W/m2/µA
08/26/2013 - PY29660 -11.98 W/m2/µA
Measured using a LICOR LI-200 Pyranometer mounted next to the primary LI-200, but outside of the rotating shading band. Voltage is measured across a 100 Ohm precision resistor in parallel to sensor output.
PSP Global Horizontal W/m2 08/18/2011 08/24/2013 27516F3 126.67 W/m2/mV
PSP 08/26/2013 01/31/2015 21231F3 109.65 W/m2/mV
SPP 01/31/2015 - 18851F3 117.92 W/m2/mV
Total Hemispheric shortwave irradiance as measured by an Eppley Laboratory, Inc. Thermopile Pyranometer with calibration factor traceable to the World Radiometric Reference (WRR).
CS215 Dry Bulb Temperature and Relative Humidity oC
%
02/03/2009 - - N/A
Outside air temperature and relative humidity inside in a naturally aspirated radiation shield mounted approx. 5 feet above ground level.
CS106 Station Pressure mBar 02/03/2009 - - 0.24 mBar/mV+500mBar
The station pressure is measured by a Vaisala sensor mounted inside weatherproof housing. This sensor is only measured every 15-minutes to conserve battery power.
(calc) Zenith Angle o 02/03/2009 - - -
Solar zenith angle calculated by RSR datalogger program.
- RSR Battery Voltage V 02/25/2009 - - -
The RSR Battery powers the datalogger and the shadowband, it is charged by a PV panel.
- CR1000 Temperature oC 02/25/2009 - - -
Temperature of CR1000 datalogger panel. Logger is mounted inside weatherproof enclosure. Note: The logger was upgraded from a CR800 to a CR1000 on 8/10/2010.
Notes:
  • Data Sample rate is every 3 second with 1-minute average output.
  • The CR1000 is a table based operating system, data is converted from table to array format after data collection, also any non-numeric values are converted to -99999.
  • The datalogger program runs using Greenwich Mean Time (GMT), data is converted to Pacific Standard Time (PST) after data collection. As of 8-19-2013, the data logger runs on PST.
