Description of the upgrade

This new version of the model is a minor upgrade including:
  1. a revised use of SSM/I radiance including a bias correction and preventing the assimilation of radiances where precipitation occurs; both satellites (DMSP-13 and 14) are now used;
  2. a modification of the assimilation of humidity in the stratosphere that was moistening unrealistically since the last model change (12 October 1999);
  3. use of coastal ship and buoy winds in the extratropical Southern Hemisphere;
  4. relaxed quality control of dropsondes
  5. implementation of Full-Pos

Implemented: 11 April 2000
