I have got a GRIB file from ECMWF for a small area in the Antarctic. It contains hourly data for one month of multiple variables (eg. wind, seaicecover, sst etc.). I want to extract this data to .txt files (every file for a different variable) at several specific locations...meaning that i have around 1000 sampling locations (stored in a text file with rows for Longitude, Latitude and ID) , for which i want to get the environmental data of the GRIB. Is there a way to get this done without doing manually? In the end a file (eg. windspeed) should have all the windspeed-values for given locations at the different times. I have already tried to use cdo and wgrib2 for example but neither of them provided me with a fitting solution or i didn't found the right tools. I am using Windows 10 (64 bit) and i've got Python 3.8 and Ubuntu 20.04 LTS installed. If you would need more specific information please let me know. I cannot include any code here because i have absolutely no idea how to approach this problem. But nevertheless here is an example of the Format of the sampling locations:
Longitude Latitude fid 1 -50.87164 -61.57444 R1 2 -60.65056 -61.30030 R2 3 -50.46169 -61.01206 R3
Do you have any idea which tool i could use for this?
