We are pleased to announce that the new MARS client with MIR, the new interpolation library replacing EMOSLIB, is now considered ready for production and suitable for operational use. It is available on all ECMWF platforms and can be accessed with:
mars -m
Using MARS/MIR through the ECMWF WebAPI can also be done by adding an extra keyword:
ppengine=mir
Although it is still not the default, we would like to encourage you to start using this new MARS/MIR client with your usual workload and report any problems or feedback to servicedesk@ecmwf.int.
MARS/MIR will become the default version at ECMWF at the end of January 2019, with the exact date to be confirmed at a later stage. The old MARS/EMOSLIB would still be accessible with:
mars -e
or, if using the WebAPI, with the keyword:
ppengine=emos
You can find some more information about this in our MARS interpolation with MIR page in this User Documentation wiki space, including the main differences and known issues. This page will be updated to reflect any changes or new features, including the exact implementation dates. You may want to "watch" this page to be notified about those updates.
Do not hesitate to contact servicedesk@ecmwf.int for more information.
