LI-200 | Global Horizontal | W/m2 | 09/12/2007 | - | PY56911 | 10.2 W/m2/mV |
Measured using a LICOR LI-200 Pyranometer mounted on an Irradiance Inc. Rotating Shadowband Radiometer (RSR). RSR mounted on the roof of a two story building (approx 33 feet tall); LI-200 sensor height is approx. 39.5 feet above ground level. | ||||||
LI-200 | Diffuse Horizontal | W/m2 | 09/12/2007 | - | PY56911 | 10.2 W/m2/mV |
Measured using the above LI-200, when RSR band rotates every 30-seconds and blocks the sun. | ||||||
(calc) | Direct Normal | W/m2 | 09/12/2007 | - | - | FD = 1.0 |
Calculated using Global and Diffuse measurement. | ||||||
CS215 | Dry Bulb Temperature and Relative Humidity | oC | 09/12/2007 | - | - | N/A |
Outside air temperature and relative humidity inside in a naturally aspirated radiation shield mounted approx. 37.5 feet above ground level on roof. | ||||||
03001 | Wind Speed and Wind Direction | m/s | 09/12/2007 | - | - | 0.75 m/s/Hz+0.2m/s 355 o/mV |
Measured by an RM Young 3-cup anemometer and vane is mounted approx 42 feet above ground level on roof. Peak Wind Speed is also recorded, which is the maximum 5-sec anemometer reading during the 1-minute interval. | ||||||
TB4 | Precipitation Gauge (tipping bucket) | mm | 10/22/2007 | - | - | 0.254 mm/count |
The Hydrological Services TES525 tipping bucket precipitation gauge is mounted approx. 38.5 feet above ground level on the roof. The accumulated daily precipitation is also recorded. | ||||||
(calc) | Est. Pressure | mBar | 09/12/2007 | - | - | - |
The station pressure is calculated by the RSR datalogger program. This estimation is based on the site elevation and air temperature. | ||||||
- | RSR Battery Voltage | V | 09/12/2007 | - | - | - |
The RSR Battery powers the datalogger and the shadowband, it is charged by a PV panel. | ||||||
- | CR800 Temperature | oC | 09/12/2007 | - | - | - |
Temperature of CR800 datalogger panel. | ||||||
(calc) | Direct Normal (Bird Estimated) | W/m2 | 09/12/2007 | - | - | - |
Estimated Direct Normal using the Bird Clear Sky Model | ||||||
