Remote Sensing Project

Calibration and validation of SST measurements

Measurements of SST from the AVHRR sensors and in situ "bucket casts" are compared. The data, supplied by Alan Pearce of CMR in Marmion, are from a transect off Hillarys, W.A. in 1998. The transect is at 31°50'S, and contains bucket casts every 5 km, starting at the coast.

The McMillin and Crosby algorithm is an empirical formula to estimate SST from the radiance measurements of the satellite sensors. The NLSST algorithm is another empirical formula to estimate SST from the radiance measurements of the satellite sensors, using additional information about the scanning geometry. This calibration and validation project is designed to show how well the algorithms match the true water temperature (as measured by bucket casts).
