735900F3Downwelling Infrared08/19/2016UOSMRLInfrared Irradiance is calculated using: I=K0+VK1+σK2Tc4+σK3(Td4-Tc4),
where σ=5.67x10-8 W/(m2K4) (Stephan-Boltzmann's Constant), V=PIR thermopile voltage in µV.
The PIR is mounted under the shading ball of a Model 2AP tracker. The Dome (Td) and Case Temperature (Tc) are also reported in degrees K.
The Instrument Net Infrared is also reported which is equal to the PIR (µV Signal) times the calibration factor K1.

13SAMPA/Bird Irradiance (Global, Direct, Diffuse)08/16/2017UOSMRLThe estimated global horizontal, direct normal, and diffuse horizontal irradiance from sun's unshaded lune.
Calculated after data collection (outside the datalogger) using the Solar and Moon Position Algorithm (SAMPA)
and Bird Clear Sky Model and added to the datastream.
As of 14-MAR-2024 @ 12:37 PST, a value of 1361.1 W/m2 is used for the solar constant for Bird Model (instead of 1367).

14Solar Eclipse Shading08/16/2017UOSMRLThe percentage area of the sun being shaded by a solar eclipse (100% = total eclipse).
Calculated after data collection (outside the datalogger) using the Solar and Moon Position Algorithm (SAMPA) and added to the datastream.
This value is equal to 100 - a_sul_pct, where a_sul_pct is the percent area of sun's unshaded lune reported by SAMPA.
