Snow tracker
- https://git.ecmwf.int/users/dako/repos/tools/browse/snow_tracker
- get_lsm.sh: retrieve land-sea mask
- get_era5.sh: retrieve snow water equivalent in ERA5 and apply mask for sea and glacier
- make_eachyear.sh: merge GRIB files to make time series of each year
- make_norm.sh: make normal values for each date (from 2005 and 2020, post IMS period)
