Comparison between GHCNv4 datasets (NOAA) and the ERA5 reanalysis (ECMWF).
- Automated download of GHCNv4 datasets from the GISS Surface Temperature Analysis (v4) website using the full list of stations (GHCNv4_stations.txt) or a subset of list of stations that contribute to the final GISTEMP v4 products (GHCNv4_stations_GISTEMP.txt).
- Possibility to select stations within a given footprint area defined by longitude and latitude coordinates.
- Function is run using multiprocessing to drastically decrease computation time.
- Matching between GHCNv4 datasets automatically downloaded with GHCNv4_automatic_download.py and ERA5 datasets.
- Possibility to store results in a pickle file (.pkl) and therefore keep the initial (varying) temporal coverage of GHCNv4 datasets.
- Option to plot a simple visualisation of temperature differences between GHCNv4 and ERA5 time series.
- Function is run using multiprocessing to drastically decrease computation time.
