1Airmass03/18/2006UNLVRelative optical airmass (not pressure corrected). Calculated after datacollection (outside the datalogger) using the Solar Position Algorithm (SPA) and added to the datastream.
As of 11-Oct-2016 at 10:45 PST, it is calculated by CR1000 using Campbell SolarPosition function (SOLPOS-based).

7Dry Bulb Temperature05/18/2006UNLVAmbient 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.
Measured using CSI P16 instruction with 1.0267 Multiplier.

12Wind Speed and Direction03/18/2006UNLVMeasured 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.

13Zenith Angle03/18/2006UNLVSolar zenith angle (refracted). Calculated after datacollection (outside the datalogger) using the Solar Position Algorithm (SPA) and added to the datastream.
As of 11-Oct-2016 at 10:45 PST, it is calculated by CR1000 using Campbell SolarPosition function (SOLPOS-based).
