The Multi-Channel Infrared Sea Truth Radiometric Calibrator (MISTRC)

A new multichannel infrared sea truth radiometer has been designed and built to improve validation of satellitedetermined sea surface temperature. Horizontal grid polarized filters installed on the shortwave channels are very effective in reducing reflected solar radiation and in improving the noise characteristics. The system uses a continuous (every other cycle) seawater calibration technique. An analysis of the data from its first deployment is presented and recommendations are made for further improving the experimental method.
