Routine production of meteograms with WRF at 1km grid size

In order to correct the Sentinel-1 interferograms produced routinely, we have set-up a routine production of « meteograms » made using the WRF code at 1km grid size in the CRL area.

A WRF model is produced for all epochs (every 30mn) and we extract those acquired at the time of the ascending and descending sentinel passes (4:30am and 4:30pm).

The difference of two WRF grids is what we call a meteogram.
