Description

To avoid confusion and complications associated with the data collection and ingest of the Infrared Thermometers (IRT), they are being separated from the Sky Radiometer (SKYRAD) and Ground Radiometer (GNDRAD) systems at the ARM sites. Historically, the analog output of the down-welling and up-welling IRTs have been sampled with a data logger to produce 1-min values of sky/cloud brightness temperature and ground surface temperature, respectively, and the serial output of the down-welling IRT has been simultaneously sampled with a computer program to produce 5-Hz values of sky temperature. The duel collection and datastreams have led to some confusion with operations, data quality, and data reprocessing. A new data acquisition system and resultant datastreams have been developed. The down-welling and up-welling IRTs are currently being reconfigured by moving the signals from the SKYRAD and GNDRAD dataloggers to the new, dedicated data acquisition systems.
