Unexpected COSMO-1E data

[brmanuel]

This may be due to my misunderstanding but some of the COSMO-1E data seems to be linked at an incorrect URI:

In the Stac-browser, accessing the https://radiantearth.github.io/stac-browser/#/external/poc.meteoschweiz-poc.swisstopo.cloud/root/collections/cosmo-1e_grib2

I'm selecting the URI

COSMO-1E - GRIB2 - 03 - 002 - T_2M

I'm assuming the components of the URI mean:

• 03 : Time of calculation of the forecast is 03:00 AM
• 002 : Leadtime is 2 hours, i.e. looking 2 hours into the future
• T_2M : Temperature 2 meters above the ground is forecast

There are 11 datasets under this URI. I'm assuming this is the ensemble of 11 forecasts. However, all 11 datasets are labeled with: Acquired = 10/1/2022, 12:00:00 PM UTC

That is, the acquired time is midnight and not 3 AM as assumed given the URI.

Moreover, the acquired time seems to be the same for all of:

• COSMO-1E - GRIB2 - 00 - 002 - T_2M
• COSMO-1E - GRIB2 - 03 - 002 - T_2M
• COSMO-1E - GRIB2 - 06 - 002 - T_2M
• COSMO-1E - GRIB2 - 09 - 002 - T_2M
• COSMO-1E - GRIB2 - 12 - 002 - T_2M
• COSMO-1E - GRIB2 - 15 - 002 - T_2M
• COSMO-1E - GRIB2 - 18 - 002 - T_2M
• COSMO-1E - GRIB2 - 21 - 002 - T_2M

Moreover, the data also seems to be exactly the same between those datasets (I checked this only for 00 and 12).

Is my understanding of the URI wrong or is there really something wrong with the linking of the data?

@p1d1d1 afaik the data is sent all three hours... so there seems an issue in the delivery into the endpoint

We have an issue here and need to investigate the cause
