Seminar 2014: Use of Satellite Observations in Numerical Weather Prediction

The 2014 Seminar was held from September 8 September 12 (finishing lunch time).


Topics covered included a discussion of the value of current and forthcoming satellite observations, with particular foci both on new types of observation and on which variables are under-observed at present. The status of assimilation of cloud-affected observations and observations over land and sea ice will be represented and progress towards a fuller exploitation of the potential of the hyperspectral sounders is addressed.

Seminar aims

The seminar is part of ECMWF's educational programme and is aimed at young scientists and scientists needing to update their knowledge in this area.
