---|---|---|---|---|---|---|
LI-200 | Global Horizontal | W/m2 | 04/06/2010 | - | PY65172 | -12.48 W/m2/µA |
Measured using a LICOR LI-200 Pyranometer mounted on an Irradiance Inc. Rotating Shadowband Radiometer (RSR). The RSR is mounted on a roof and the LI-200 sensor height is approx. 7 feet above roof 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 | 04/06/2010 | - | PY65172 | -12.48 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 | 04/06/2010 | - | - | FD = 1 |
Calculated using Global and Diffuse measurement. The uncorrected value is for testing and troubleshooting purposes only. | ||||||
LI-200 | Global Horizontal (secondary) | W/m2 | 04/06/2010 | - | PY65173 | -12.89 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 % |
04/06/2010 | - | - | N/A |
Outside air temperature and relative humidity inside in a naturally aspirated radiation shield mounted on RSR pole below LICOR sensors. | ||||||
034B | Wind Speed and Wind Direction | m/s degrees |
04/08/2010 | - | - | 0.799 m/s/Hz+0.2811m/s 712 o/mV |
Measured by a MetOne 3-cup anemometer and vane mounted on a 3 meter pole on the top of a roof. Peak Wind Speed is also recorded, which is the maximum 3-sec anemometer reading during the 1-minute interval. | ||||||
CS106 | Station Pressure | mBar | 12/20/2010 | - | - | 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. Note: Pressure sensor was installed 12/20/2010, data reported prior to this date is estimated based on site elevation. | ||||||
TB4 | Precipitation Gauge (tipping bucket) | mm | 04/06/2010 | - | - | 0.254 mm/count |
The Hydrological Services TES525 tipping bucket precipitation gauge is mounted 4 feet above roof level. The accumulated daily precipitation is also recorded. | ||||||
(calc) | Zenith Angle | o | 04/06/2010 | - | - | - |
Solar zenith angle calculated by RSR datalogger program. | ||||||
(calc) | Azimuth Angle | o | 04/06/2010 | - | - | - |
Solar azimuth angle calculated by RSR datalogger program. | ||||||
- | RSR Battery Voltage | V | 04/06/2010 | - | - | - |
The RSR Battery powers the datalogger and the shadowband, it is charged by a PV panel. | ||||||
- | CR1000 Temperature | oC | 04/06/2010 | - | - | - |
Temperature of CR1000 datalogger panel. Logger is mounted inside weatherproof enclosure. | ||||||
