This program converts time series Standardised Precipitation-Evapotranspiration Index (SPEI) data from the netcdf format to a csv format which could be read by a program such as Excel. The SPEI data is available at https://spei.csic.es/index.html.
Although parallelized, for large datasets the conversion might take a while.
The column headers are Time, Latitude, Longitude and SPEI value in that order.
pip install convertSPEI

convertSPEI.py -h
convertSPEI.py -np 20 -inp spei01.nc -out spei01_converted.csv
where,
- np : the number of processors
- inp : input file name
- out : output file name
Note:
If Memory Error occurs, reduce the number of processors to provide more memory per core for the conversion.
