Info

Note that as a consequence, MIR does not apply land-sea mask processing when using the nearest neighbour method, which was the case in EMOSLIB. Actually, the EMOSLIB interpolation "nearest neighbour" and "nearest lsm" produce the same results.

Grid to grid interpolations

EMOSLIB cannot handle interpolations from a regular latitude-longitude grid to a reduced gaussian, but MIR does not have that limitation. Interpolations from any global regular or reduced gaussian or latitude-longitude grids to regular or reduced gaussian or regular latitude longitude grids are now supported in MIR.

RESOL=AV uses wrong intermediate Gaussian grid

When using RESOL=AV and transforming from spectral to grid, the corresponding intermediate Gaussian grid to be used should be the cubic reduced Gaussian grid by default (i.e., O = T+1), as described above. However, at this point MIR uses a full (regular) gaussian grid with linear truncation (i.e., F = (T+1)/2).

This issue has been resolved in a version of the MARS client using MIR (version 0.8.5) released on 14 November 2017.

Winds on rotated grids

There are known issues with wind fields when working with rotated grids. In particular, wind speeds are correct but the direction is wrong due to a problem in computing the angles.
