---|---|---|---|---|---|---|
LI-200 | Global Horizontal (Bovoni 2) | W/m2 | 12/13/2012 | 08/25/2014 | PY75521 | -114.12 W/m2/mV |
Measured using a LICOR LI-200 Pyranometer mounted to the south of the tower. Voltage is measured across a 100 Ohm precision resistor in parallel to sensor output. The second "Ref" measurement is for NREL calibration check purposes and should not be used by the user. | ||||||
#110S | Dry Bulb Temperature (Bovoni 2) | oC | 12/13/2012 | 08/25/2014 | - | 0.05555 oC/mV-86.38oC |
Outside air temperature inside in a naturally aspirated radiation shield mounted at 2 meters. | ||||||
#40C | Wind Speed (Bovoni 2) | m/s | 12/13/2012 | 08/25/2014 | - |
0.769 m/s/Hz+0.36 m/s 0.765 m/s/Hz+0.36 m/s 0.768 m/s/Hz+0.35 m/s 0.769 m/s/Hz+0.35 m/s 0.765 m/s/Hz+0.31 m/s 0.769 m/s/Hz+0.36 m/s |
Measured by (6) calibrated NRG 3-cup anemometers at 58, 47, and 32 meters (at both 45 and 135 degree boom orientations [TN]). The peak wind speed is also recorded, which is the peak 1-second reading during the 1-minute interval. Note: Data from 45 TN are used with the MIDC Wind Roses. | ||||||
#200P | Wind Direction (Bovoni 2) | degrees | 12/13/2012 | 08/25/2014 | - | 360 o/mV+90 o |
Measured by (2) NRG wind vanes mounted at 52 and 35 meters. Notice: Data has been mis-labeled as 58 and 32 meters to allow the measurements to be compatible with MIDC Wind Roses. | ||||||
#BP20 | Station Pressure (Bovoni 2) | mBar | 12/13/2012 | 08/25/2014 | - | 0.2179 mBar/mV+109.8mBar |
The station pressure is measured by a NRG sensor mounted at a height of 2 meters. | ||||||
CR1000 | CR1000 Battery Voltage (Bovoni 2) | V | 12/13/2012 | 08/25/2014 | - | - |
The CR1000 battery voltage. Battery is charged by PV panel. | ||||||
CR1000 | CR1000 Temperature (Bovoni 2) | oC | 12/13/2012 | 08/25/2014 | - | - |
Temperature of CR1000 datalogger panel. Logger is mounted inside weatherproof enclosure. | ||||||
LI-200 | Global Horizontal (Longford) | W/m2 | 12/13/2012 | 03/15/2013 | PY75520 | -110.21 W/m2/mV |
05/03/2013 | 12/20/2013 | PY75523 | 119.90 W/m2/mV | |||
Measured using a LICOR LI-200 Pyranometer mounted to the south of the tower. Voltage is measured across a 100 Ohm precision resistor in parallel to sensor output. The second "Ref" measurement is for NREL calibration check purposes and should not be used by the user. | ||||||
