| Summary: | disseminated on the GTS in BUFR format. • 5 April 2005: Implementation of Cycle 29r1. This version included a new moist boundary layer scheme (more stratocumulus clouds in subtropical highs and better handling of anticyclonic low level clouds), a wavelet formulation for background error statistics (Jb), a revised use of surface pressure observations (including the use of METAR reports and an adaptative bias correction scheme) and the use of MODIS winds from AQUA (in addition to TERRA). • 28 June 2005: Implementation of Cycle 29r2. This included the use of new data (i.e. rain-affected SSM/I radiances, Meteosat-8 (MSG) AMVs and the Baltic sea-ice analysis from SMHI) and also some refinements in the use of existing data. Jb statistics from the new ensemble data assimilation were introduced, as well as convection changes affecting mainly low level winds. • Spring 2005: EPSgrams for WMO users made available for capital cities of WMO members at: |
