Table D 40, BUFR template for DMSP satellites

[marijanacrepulja]

Initial request

In support for assimilation of DMSP satellites in ERA6, ECMWF is proposing new BUFR template for representation of observations from SSM/T1, SSM/T2 and SSH instruments.

@marijanacrepulja there is a comment in the PR and I changed the reference in the title from Table D 10 to 40.

@sergioh-pessoal I have uploaded sample BUFR file and output of decoding. Many thanks for supporting validation.

Hi @marijanacrepulja
I downloaded the table from the branch in git
Apparently, there is an error in the DELAYED REPLICATION OF 11 DESCRIPTORS (1-11-000). Note that in fact there are only 10 descriptor bellow that to be replicated. (The 031001 should not be counted ).

I was be able to successfully decoded the sample after replaced 1-11-000 by 1-10-000
I checked the values and it is the same of the text provided.

So I think that this template can be considered validated

But it is necessary to replace the descriptor 1-11-000 to 1-10-000 in the table.

The result is attached

@sergioh-pessoal Many thanks for supporting the validation and for spotting the typo in delayed replication. The sample was encoded using 1-10-000.
