The new ECMWF interpolation package MIR (see ECMWF Newsletter No. 152) is now ready for testing by users of the MARS archive.
A version of the MARS client using MIR (MARS/MIR) is available on all ECMWF platforms and can be accessed using the command ‘mars -m’. It can also be tested using the ECMWF Web API adding the key word ‘ppengine=mir’. MARS/MIR is not considered ready for production at this point and should only be used for testing purposes.
MARS users are encouraged to test this new MARS/MIR client with their usual workload and report any problems or feedback to ECMWF.
The expected timeline for the operational implementation of MARS/MIR is as follows:
- June 2018: Release of a MARS/MIR client considered ready for production. The old MARS/EMOSLIB client will still be the default.
- Autumn 2018: MARS/MIR becomes the default version at ECMWF. The old MARS/EMOSLIB will still be accessible, but there will be no further updates to it.
Users can find more information about MARS/MIR in the ECMWF User Documentation wiki space, including the main differences and known issues:
