LI-200 | Global Horizontal | W/m2 | 11/10/2010 | - | PY58689 | CF = -10.96 W/m2/µA FD = 1.0261 |
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 | 11/10/2010 | - | - | - |
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 | 11/10/2010 | - | - | FD = 1.0261 |
Calculated using Global and Diffuse measurement. The uncorrected value is for testing and troubleshooting purposes only. | ||||||
LI-200 | Global Horizontal (secondary) | W/m2 | 11/10/2010 | - | PY63285 | CF = -11.48 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. | ||||||
CS215 | Dry Bulb Temperature and Relative Humidity | oC | 11/10/2010 | - | - | N/A |
Outside air temperature and relative humidity inside in a naturally aspirated radiation shield mounted approx. 5 feet above ground level. | ||||||
034B | Wind Speed and Wind Direction | m/s | 11/10/2010 | - | - | 0.799 m/s/Hz+0.2811m/s 712 o/mV+45o |
Measured by a Met One 3-cup anemometer and vane mounted 10 meters above ground level on tower. Peak Wind Speed is also recorded, which is the maximum 3-sec anemometer reading during the 1-minute interval. | ||||||
TE525 | Precipitation Gauge (tipping bucket) | mm | 11/10/2010 | - | - | 0.254 mm/count |
The Texas Electronics TR525I tipping bucket precipitation gauge is mounted approx. 4 feet above ground level. The accumulated daily precipitation is also recorded. | ||||||
CS106 | Station Pressure | mBar | 11/10/2010 | - | - | 0.24 mBar/mV+500mBar |
The station pressure is measured by a Vaisala PTB110 sensor mounted inside weatherproof housing. This sensor is only measured every 15-minutes to conserve battery power. | ||||||
(calc) | Zenith Angle | o | 11/10/2010 | - | - | - |
Solar zenith angle calculated by RSR datalogger program. | ||||||
(calc) | Azimuth Angle | o | 11/10/2010 | - | - | - |
Solar azimuth angle calculated by RSR datalogger program. | ||||||
(calc) | Airmass | - | 11/10/2010 | - | - | - |
Airmass (optical) and airmass (pressure corrected) calculated by RSR datalogger program. | ||||||
- | RSR Battery Voltage | V | 11/10/2010 | - | - | - |
The RSR Battery powers the datalogger and the shadowband, it is charged by a PV panel. | ||||||
- | CR800 Temperature | oC | 11/10/2010 | - | - | - |
Temperature of CR800 datalogger panel. Logger is mounted inside weatherproof enclosure. | ||||||
