Broadband radiometers (Eppley)
Short Name or Variable Name
Eppley PSP and PIR
Total visible (short-wave) radiation and infrared (long-wave) radiation in a hemisphere. Often deployed in pairs to measure radiation incoming and outgoing from the surface.
ISFS has added microprocessor-based A/D boards inside each of these sensors to save and apply the calibration coefficients.
Calibration Methods
PSP are calibrated by NOAA/GMD against standard pyranometers on their roof.
PIR (pyrgeometers) are calibrated in the EOL calibration laboratory using a dual temperature-controlled oil bath.
The calibration coefficients for each sensor are loaded into an onboard microprocessor.
