convertSPEI

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. </br> Although parallelized, for large datasets the conversion might take a while. The column headers are Time, Latitude, Longitude and SPEI value in that order.
