Impact of the increased resolution
• 1. We have started using higher resolution data as boundary conditions for
our model runs. We are planning to upgrade our large streams when we
reorganise all our dissemination from ECMWF (after summer).
2 and 3. We have primarily experienced problems with write bandwidth to
disc, we are in the process of upgrading our netapp filers to "all flash"
versions to cope with both the increased ecmwf resolution and the
introduction of our MEPS (Metcoop Ensamble Prediction System). The plan
is to finish the upgrade beginning of June to be ready to release both MEPS
and higher resolution ECMWF data to production.
4. We are starting to use second order packing for some high resolution
model level data. Examples during ecCodes course showed complex packing
being really slow to decompress and this might be a problem for our main
dissemination of data (tests will be perfomed).
