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).,,NV,UNLV,,,AMASS 2,,Azimuth Angle,03/18/2006,UNLV,Solar azimuth angle. 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).,,NV,UNLV,,,AZM 3,,Diffuse Horizontal,04/06/2006,UNLV,Diffuse is calculated using the formula: Global = Direct * Cosine(Zenith) + Diffuse.,,NV,UNLV,,,DH 4,31874E6,Direct Normal,04/06/2006,UNLV,Mounted in an automatic sun-following tracker,06/18/2008,NV,UNLV,Eppley,NIP,DN 5,25791E6,Direct Normal,06/18/2008,UNLV,Mounted in an automatic sun-following tracker,07/10/2008,NV,UNLV,Eppley,NIP,DN 6,31874E6,Direct Normal,07/10/2008,UNLV,Mounted in an automatic sun-following tracker,,NV,UNLV,Eppley,NIP,DN 7,,Dry Bulb Temperature,05/18/2006,UNLV,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.
Measured using CSI P16 instruction with 1.0267 Multiplier.,,NV,UNLV,,,TH 8,910126,Global Horizontal,03/18/2006,UNLV,,,NV,UNLV,Kipp & Zonen,CM3,GH 9,,Logger Battery Voltage,03/18/2006,UNLV,CR23X data logger battery voltage. The logger was upgraded to a CR1000 on 10-OCT-2016.,,NV,UNLV,,,CRT 10,,Logger Temperature,03/18/2006,UNLV,CR23X data logger panel temperature. The logger was upgraded to a CR1000 on 10-OCT-2016.,,NV,UNLV,,,CRB 11,020615,UVA and UVE (Erythema),03/18/2006,UNLV,The Kipp & Zonen dual band sensor measures both UVA in W/m^2 and UVE (erythema) in W/m^2 and the UV-Index.
