New Table B descriptors, Sea-surface height anomaly measurement #213

Open marijanacrepulja opened 5 days ago

marijanacrepulja commented 5 days ago

Initial request

In support to assimilation of sea surface height anomalies in ocean models, there is a need to represent available measurements in BUFR. Raw observations are in netCDF format.

CMEMS-SL-PUM-008-032-068.pdf

Amendment details

1. Add a new table B descriptor 0-08-xxx for Type of Sea-surface height anomaly measurement F X Y ELEMENT NAME UNIT SCALE REFERENCE VALUE DATA WITH (bits)
0-08-xxx Type of Sea-surface height anomaly measurement Code table 0 0 3
2. Add a new CODE/FLAG TABLE 0-08-xxx for Type of Sea-surface height anomaly measurement Code Type of Sea-surface height anomaly measurement
0 Unfiltered, raw measurement including noises
1 Filtered, low-pass filtered sea surface height for noise reduction
2-6 Reserved
7 Missing value
3. Add a new table B descriptor 0-21-xxx for Dynamic Atmospheric Correction F X Y ELEMENT NAME UNIT SCALE REFERENCE VALUE DATA WITH (bits)
0-21-xxx Dynamic Atmospheric Correction Numeric -65536 3 17
