Grib Reader

A few scripts to read, reproject and rasterize GRIB, GRIB2 or NetCDF data, from Copernicus ERA5 model, to a data serie in csv.

Usage/Examples

Examples how to use

Reproject and save as Geotiff

This script takes a directory full of grib files, reprojects them to WGS84 and save it as a raster in GeoTiff format.

    python gen_geotiff.py --path /path/to/grib/files 

Extract data

This scripts use the points declared in a shapefile, get the data from de rasters and generate a serie in a csv file.

    python rasterize.py --path /path/to/geotiff --shapefile /path/to/shapefile 

Calculate wind direction and speed

Because the model has U and V components of wind, and wind speed (wspd) and wind direction (wdir) are desired.

    python products.py --path /path/to/U_V_csv/file
