title = "Improvements in the Blackbody Calibration of Pyrgeometers (Poster)",
abstract = "Pyrgeometers are used to measure the atmospheric longwave irradiance throughout the ARM program sites. Previous calibrations of pyrgeometers using ARM/Eppley/NREL blackbody were consistent, but introduced a difference in the historical clear sky measured irradiance. This difference was believed to be in the order of 12 W/m2. In this poster we show the improvements to the blackbody and calibrationmethodology by comparing our results to the results of a group of pyrgeometers that were recently calibrated against the World Infrared Standard Group, in the World Radiation Center, Davos/Switzerland.",
