Hello,
I am using inverse distance weighting with gstat for temperature just to
compare it with other kriging methods. For a temperature field, I have removed
the elevation effect at the stations by normalizing all stations to the lowest
with a lapse rate of -6.5 deg C /1000 m.
Now, I want to krig the normalized data and then add back the lapse rate
multiplied by the difference in elevation to get the real temperatures at all
real elevations. However, how can I do this before cross validation?
I only know cross validation with the following command where it does not allow
manipulation of the kriged field before cross validation:
crossval_idw <- krige.cv(Temp93hr~1, DataCoordhr)
Thank you in advance for your help.
Cheers,
Cara
