How to add custom scale to SPI/SPEI computation for NetCDF data? #120

Open devisdevis opened 1 month ago

devisdevis commented 1 month ago

Hello,

Please I would like to compute custom scale SPI/SPEI indices for NetCDF data in ClimPact2? Is there any detail in the documentation about the use of user-defined values for NetCDF data?

Thanks

This isn't supported for netcdf, but the code change should be trivial. You could try changing both instances of "scale <- c(3,6,12)" in climpact.etsci-functions.r. This hasn't been tested but give it a go.

Thanks, it works but the attribute (names) remain identical, which is confusing. What file could be tweaked to get the attributes right? Also, when I try to increase the number of SPI/SPEI scales (more than 3 scale levels like c(3,6,9,12,24)) and modify the ncdf.R in 'climdex.pcic.ncdf', it doesn't work. Any clue to solve that please?
