assess the WIS 1.0 catalogue for availability of NWP data about wcmp

[tomkralidis]

Update 2021-05-21: @efucile will provide list of centers providing NWP.

@josusky and @tomkralidis to develop MVP.

[efucile]

@tomkralidis and @josusky this is a list of GDPFS centres. There is a column saying which of them is supposed to provide data in WIS. This can be used to check which of the centres in the list is also providing data in the catalogue.
GDPFS Centers

Just for the record,, the whole WIS metadata catalogue can be downloaded from https://gisc.dwd.de/oaidownload/wis-catalogue.tar.gz. I guess that can be considered and authoritative source :-)

[tomkralidis]

Thanks @josusky. To clarify, is this the result of DWD GISC harvest of all GISCs? How often is the .tar.gz updated? cc @jsieland

Yes, it's everything. At https://gisc.dwd.de/wisportal/# (see "Metadata") you can choose between all or only GISC Toulouse or only GISC Offenbach. Should be updated every night.

I am pasting here part of the discussion with Tom over Slack:
When I go to https://gisc.dwd.de/wisportal/# and search for "NWP model GRIB" I get (allegedly) 110978 results. A more machine friendly approach is to use SRU:
https://sru.dwd.de/SRU2JDBC/sru?operation=searchRetrieve&version=1.1&startRecord=1&maximumRecords=5&query=title%20=%20model%20and%20abstract%20=%20NWP&stylesheet=xsl/dwd-sru.xsl&x-dwd-stylesheetDetailLevel=1
this surprisingly finds only 2985 matches (the request definitely needs tuning). Such request could be done from a script. The number of responses per requests is usually limited so we would need to repeat the request.
The other alternative is to run a script locally on top of the catalogue retrieved as the *.tar.gz. That might be faster but requires own implementation of a search algorithm.

[tomkralidis]

Aside: I've captured the WIS catalogue location information in the wiki for future use: https://github.com/wmo-im/wcmp/wiki/WISMetadataCatalogue#wis-10-metadata-catalogue

Please feel free to update.

[tomkralidis]

An initial implementation can be found in https://github.com/wmo-im/pywiscat; @josusky to review/update accordingly, at which point we'll be able to provide an analysis of NWP data.

Different search result numbers occure due to differences in search query
https://sru.dwd.de/SRU2JDBC/sru?operation=searchRetrieve&version=1.1&startRecord=1&maximumRecords=5&query=title%20=%20model%20and%20abstract%20=%20NWP&stylesheet=xsl/dwd-sru.xsl&x-dwd-stylesheetDetailLevel=1
--> title=model AND abstract=NWP

Search over
https://gisc.dwd.de/
"NWP model GRIB"
--> 111 023 matches
searches over all indexed fields for "NWP" OR "model" OR "GRIB"
Search "NWP AND model AND GRIB" (but still over all indexed fields)
--> 24 957 matches

[SolR-supported operators: AND – alternative symbol: &&, NOT – alternative symbol: !, OR – alternative symbol: || [DEFAULT]]

Of interest could possibly also be our new REST API in the WIS Portal. A first version of a doc is available at
https://gisc-test.dwd.de/restapi.html
if you have any questions, we will be happy to help you.

Hi, a first very crude test (looking only for the word "GRIB") yielded the following result (in the JSON output non-ASCII characters are encoded):

this shows several potential issues. Several centers are listed more than once, for example, "ECMWF" is obviously the same thing as "European Centre for Medium-Range Weather Forecasts". And there is granularity again. JMA published 21372 records while DWD "only" 1246, but that does not mean that JMA is doing its job by an order of magnitude better :-)

@efucile , sorry for the delay. I have run an updated version of pywiscat (that groups the output by citation authority extracted from the file identifier URI) after our last teleconference but forgot to publish the result.
