Cycle 25r1 summary of changes

9 April 2002 Introduction of Cycle 25r1. This version includes the following changes:

  1. A revised shortwave radiation scheme with variable effective radius of liquid cloud water;
  2. Retuning of the land surface (TESSEL) parametrization to reduce winter/spring warm biases in low-level temperatures;
  3. Improved physics for the oceanic wave model;
  4. Improved wind-gust post-processing;
  5. The activation of new data streams in the assimilation: water-vapour radiances from Meteosat-7, SBUV and GOME ozone data, and European wind profilers;
  6. A bug in the convective momentum transfer was also fixed;

Please note

Prior to 2006 information on cycle upgrades has been migrated from the old website to the new website "as is". The information has not been reviewed during the migration.
