| CM3 | Global Horizontal | W/m2 | 03/18/2006 | - | 910126 | 84.104 W/m2/mV |
| [DQS]
[Maint] |
Total Hemispheric shortwave irradiance as measured by an Kipp & Zonen Model CM3 Pyranometer with calibration factor traceable to the World Radiometric Reference (WRR). | |||||
| NIP | Direct Normal | W/m2 | 04/06/2006 | 06/18/2008 | 31874E6 | 125.0 W/m2/mV |

| [DQS]
[Maint] |
Direct (Beam) shortwave irradiance as measured by an Eppley Laboratory, Inc. Model NIP (Normal Incidence Pyrheliometer) mounted in an automatic sun-following tracker, with calibration factor traceable to the WRR. The estimated broadband Aerosol Optical Depth (AOD) is also calculated using this instrument. | |||||
| (calc) | Diffuse Horizontal | W/m2 | 04/06/2006 | - | ||
| [DQS]
[Maint] |
Diffuse (Sky) shortwave irradiance is calculated using the formula: Global = Direct * Cosine(Zenith) + Diffuse. | |||||
| 41342 | Dry Bulb Temperature | oC | 05/18/2006 | - | ? | P16 w/1.0267 Mult |
| [DQS]
[Maint] |
Ambient air temperature measured with an RM Young 1000 Ohm 4-Wire RTD inside in a naturally aspirated radiation shield mounted on a pole at approximately 30 feet above ground. The wind chill temperature is also calculated using the new National Weather Service (NWS) method as described on the NOAA web site, however the wind speed used is measured at approx. 30' instead of the 5' level required by the NWS calculation. | |||||
| 05103 | Wind Speed and Wind Direction | m/s | 03/18/2006 | - | ? | 0.098 m/s/Hz 0.355 o/mV |
| [DQS]
[Maint] |
Measured by an RM Young 4-blade propeller and attached vane mounted on a pole at approximately 30 feet above ground. Peak Wind Speed is also recorded, which is the maximum 1-sec anemometer reading during the 1-minute interval. | |||||
| UV-S-AE-T | UVA and UVE (erythema) | W/m2 W/m2 Index |
03/18/2006 | - | 020615 | 25.167 UVA-W/m2/V 0.123 UVE-W/m2/V 40.0 Index/UVE-W/m2 |
| [DQS]
[Maint] |
The Kipp & Zonen dual band sensor measures both UVA in W/m2 and UVE (erythema) in W/m2 and the UV-Index. The unit is temperature controlled at 25 oC. | |||||
| CR23X-T | CR23X-PB Temp | oC | 03/18/2006 | - | ||
| CR23X internal temperature. | ||||||
| CR23X-B | CR23X-PB Battery Voltage | oC | 03/18/2006 | - | ||
| CR23X internal battery voltage. | ||||||
| (calc) | Zenith Angle | o | 03/18/2006 | - | ||
| Solar zenith angle (refracted). Calculated after datacollection (outside the datalogger) using the Solar Position Algorithm (SPA) and added to the datastream. | ||||||
| (calc) | Azimuth Angle | o | 03/18/2006 | - | ||
| Solar azimuth angle. Calculated after datacollection (outside the datalogger) using the Solar Position Algorithm (SPA) and added to the datastream. | ||||||
| (calc) | Airmass | - | 03/18/2006 | - | ||
| Relative optical airmass (not pressure corrected). Calculated after datacollection (outside the datalogger) using the Solar Position Algorithm (SPA) and added to the datastream. | ||||||
