Add script to interpolate ITS_LIVE dh/dt and surface fields to MALI mesh for a user-specified time period. Based on the ITS_LIVE data set connected with https://doi.org/10.5194/essd-18-1729-2026. Note that this does not automatically update the thickness field based on the average surface field calculated from the ITS_LIVE data, but that can easily be done with an ncap2 command if desired..

Testing

Testing on a 4–40km Greenland mesh:

This runs in just a few minutes on one PM compute node.

Add command to netCDF history to document time period, source file,
and interpolate method.
Use mpas_tools.io.write_netcdf instead of xr.to_netcdf. The previous
treatment causes MALI to crash when reading the input file.
