Sea Surface Temperature algorithms

This page contains the coefficient file used for the SST algorithm. It also gives links to the previously used coefficient files.

Version number

The coefficient files are labeled with an algorithm version number. The format of the version number is:

nX.YpZ.W (e.g. n1.2p2.0)

where an increasing X,Y,Z or W indicates that there has been a change to the coefficient file. For each upgrade of the coefficient file one or more of the version numbers are increased by 1. The four version number indicates the following changes:

X
Coefficients for new satellite from new satellite mission have been included (e.g. METOP in 2007).
Y
Coefficients for new satellite from existing satellite mission have been included (e.g. new NOAA satellite).
Z
Coefficients of existing algorithm have been changed (e.g. bias correction).
W
Other changes.

Present coefficients

At present this coefficient file is used: alg_nlsst_n13p20.txt.
