Issues to be reviewed

GRIB2

In progress

1. A product definition template for statistics over an ensemble

In validation

2. Representing gnomonic grids
3. New Table 4.2 entries proposed by Canada
4. New GRIB2 code Table 4.2 entries requested by Norway

BUFR4

Submitted

1. New Sequence and descriptors for GNSS Slant Total Delay BUFR Ms Krebber presented the sequence and requested the team to accept for validation with the aim to be included in FT-2021-1. The opportunity to put the notes in a column description has been discussed. The option of dividing in two sequences has been discussed. Accepted for validation.
2. new entries in BUFR flag table 0-33-066 Mr. Ator introduced the proposal and requested the have the proposal approved for validation with the aim for FT-2020-2. Approved for validation. A request to the Secretariat to provide a validation template to be used as a comment in the gitHub issue. The team discussed the fact that there are other sequences for scatterometer data and in Europe KNMI is sending most of the scatteromenter data in another sequence. Another sequence for scattermometer has been proposed in another issue for CFOSAT (https://github.com/wmo-im/BUFR4/issues/20).
3. New BUFR Table B and D descriptors for scatterometer data
4. Proposal for new BUFR table entries for Sentinel-6 Michael Freilich
5. Table D sequence for reporting scatterometer data from CFOSAT
6. New BUFR sequences for encoding IKFS2 products
7. Correct clerical error in BUFR Table B entry 0-40-063

In validation

8. Additional bio-geochemical sequences for data from Argo profiling floats
9. Table D sequence for reporting marine observations from unmanned surface vehicles

Common Code Tables

Submitted

1. Add 3 new entries to C-2 for radiosondes of China
2. Amendment to Common Code table C-3 by Japan
3. Add a new entry to Common Code Tables C-11 to identify IAP
4. new CCT C-1/11, C-5 and C-8 entries for commercial providers of radio occultation data
5. Proposal for new entries in Common Code Tables C5 and C8
6. Proposal for new entry in Common Code Tables C5
7. New sub-category for TC tracks from deterministic in C-13
8. New sub-category for Mode-S in C-13
9. add new chemical species, aerosols and pollen in Common Code Table 14
