Producing climate data records of sea-surface temperatures from measurements from spacecraft radiometers.

Abstract

The retrieval of sea-surface temperatures (SSTs) from satellite radiometers is now quite routine. Given accurate on-board calibration of the radiance measurements to provide top-of-atmosphere brightness temperatures, the generation of SSTs requires the successful correction for the effects of the intervening atmosphere. The determination of the residual error characteristics of the SST retrievals is a vital aspect of establishing the utility of these fields in a wide range of applications including weather and ocean forecasting, and in climate research. The error characteristics are established by comparisons between the satellite SST retrievals and ship-based measurements from well-calibrated radiometers measuring the skin SST and sub-surface temperatures from buoys. The requirements of a “Climate Data Record” (CDR) include well characterized error estimates and traceability to a National Standard, if feasible. This presentation will cover the generation of CDRs of SSTs based on comparisons of the skin SST measured by ship-based infrared radiometers with calibration traceable to NIST (National Institute of Standards and Technology) temperature and radiometry standards.
