- Standard development for Uncrewed Aircraft Systems (UAS): new activity - Dean Lockett (WMO)
- Dean presented on UAS: this activity comes through an approval by WMO Infrastructure Commission and limitation is use of airspace; outcome from workshop in 2019 was to work towards a demonstration of the systems and their potential contribution to meteorology and to develop the terms of reference for this campaign; the demo will start in 2023; https://community.wmo.int/uas-demonstration; they are working on developing UAS data representation with CF-NetCDF format initially and then translate to BUFR representation from NetCDF. (Jitsuko) Is there an expert team on the demo team? (Dean) there is an ad-hoc sub-group under the JET-ABO to develop the standard formats and there is a WMO committee for organizing the campaign. (Jitsuko) Mariana and Simon can propose these formats to the ET-Data Task Teams, probably next year. (Simon) the approach could be similar to the CF-NetCDF profile for weather radar data (for the NetCDF data format); (Dean) the campaign doesn't require fully adopted data formats to move forward.
- DAYCLI BUFR sequence: status update
- (Jitsuko) Sergio provided some sample data, doing final checking of the time period approach to make sure that the proposed sequence can represent all of the existing practices and hopefully this can be approved during FT2022-1. (Sergio) testing with software and also asking for extra samples for the check. (Jitsuko) The branch needs to be updated as soon as possible to reflect latest decisions for decoding.
