3. SST from AATSR:
Summary and conclusions

In this lesson you have looked in detail at how AATSR top of atmosphere (TOA) brightness temperature (Tb) data are processed in order to retrieve sea surface skin temperatures (SSTskin). You have seen how data from the nadir and forward views may be used to calculate atmospheric attenuation, and identify clouds more clearly. You should also now have an idea of the artefacts that may results from the geometric displacement between nadir and forward views, particularly in regions with rapidly changing temperature gradients.

You will also have seen how high resolution SST data may be used to study current oceanographic phenomena such as upwelling, current eddies and the mixing of water masses across fronts. The image used here is a particularly good examples of different features seen in SST data, and how these may be related to currents and wind fields.
