| LI-200 | Global Horizontal | W/m2 | 02/03/2009 | - | PY61283 | -10.44 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 | - | PY61283 | -10.44 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 | - | - | FD = 1.03378 |
| 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 | - | PY61743 | -10.36 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 | - | 27516F3 | 126.67 W/m2/mV | Total Hemispheric shortwave irradiance as measured by an Eppley Laboratory, Inc. Model PSP (Precision Spectral 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. | ||||||
