Have a nice day everyone,
II need to downscale my simulated GCM and RCM datasets. Is it possible for me to carry out the downscaling operation by increasing the resolution of my nc file with the help of the script written below? The script denotes the "Bilinear Interpolation" method on CDO. Plus, if this method below is counted as a separate downscaling method, what is the name for this kind of downscaling/bias-correction method?
cdo remapbil,r720x360 inputfile.nc outputfile.nc
Thanks in advance
Best of luck
For sure, this cdo command can only interpolate, but cannot be considered as "downscaling". To my opinion, it shouldn't be applied to increase the target resolution, at least I do not see any real added value.
1: The possibly (best) way for downscaling is dynamic downscaling, which can create added values.
2: The parsimony way is interpolation (as you mentioned) coupled with the bias correction, but keep in mind that the spatial gap should be small.
3: Bias correction sometimes is used directly.
