Subject: | SGP/CO2/C1 - downwelling longwave hemispheric irradiance incorrect |
DataStreams: | sgp30co2flx4mmetC1.b1 |
Description: | A problem was identified with the downwelling longwave hemispheric irradiance (variable "r_down_long_hemisp") calibration of our Kipp & Zonen CNR1 radiometer. The offset of the instrument is believed to be incorrect over the specified time frame, and a correction of the problem is underway. |
