Inter-session Changes
- METAR, SPECI and TAF: weather code IC (ice crystal) removed, significant wave height introduced
- SYNOP, SHIP, and CLIMAT: encoding of trace and outscaled preciptation amounts
- GRIB2: identification definition templates introduced for calendar identification
- GRIB2: generalized vertical height coordinate using UUID reference to external objects
- BUFR/CREX: clarification of descriptor 0 20 054 (True direction of a phenomenon or clouds)
Fast-track Changes
- EUCOS BUFR template for high-resolution radiosonde data (TM309055) which uses geopotential height as the vertical coordinate
- BUFR/CREX template for AOT (aerosol optical thickness) data from NPOESS preparatory project (TM310064) and related C-14 additions
- BUFR/CREX template for OMPS (ozone mapping and profiler suite) nadir profile data from NPOESS preparatory project (TM310065) and related C-14 additions
- New C-14 code (Atmospheric chemical or physical constituent type) for NOx (60017)
- New C-12 code (Sub-centres) for JMA/Reanalysis project and NOAA/OAR laboratories
- BUFR/CREX element 0 20 137 (Evolution of clouds) to accomodate SYNOP migration
