CDO

Added by Marco Alves 1 minute ago

Hi,

I have several datsets from ERA5-Land reanalysis on a grid with one variable only, which is accumulated from the beginning of the forecast time to the end of the forecast step. How can I extract the single values associated to each timestep?

I am currently trying the following sequence as a test:

#!/bin/bash
for m in `seq 1 4`
do
file=evaporation_from_the_top_of_canopy_198${m}.nc

nstep=`cdo ntime $file`

cdo sub -seltimestep,2/$nstep $file -seltimestep,1/`expr $nstep - 1` $file diff_198${m}.nc

cdo mergetime -seltimestep,1 $file diff_198${m}.nc evatc_198${m}.nc

done

However, the output files I am getting have only values from 1 Jan to 17 May. Does anyone knows a better way of extracting this values?
I really appreciate the help!

Cheers,
Marco
