Calculate the maximum value over multiple daily timesteps
Added by Theodoros Gkousarov about 11 years ago
Hi guys,
I have a file with daily mean values of solar radiation over a period of 20 years. (20y.nc) I want to create a file which will contain the maximum value of daily solar radiation per location. So that I can create a map showing the maximum daily solar radiation reached at any day during the 20 years.
Can somebody help me?
Thanks.

Hi,
use "ydaymax" operator, ie,
cdo -ydaymax 20Year_daily_mean_file ofile
Cheers,

PS: sorry I think I used the wrong operator before. It should be "ydaymax" instead of "timmax" I guess

oh alright, i thought that i went crazy when i calculated with timmax and then got back here to find it as ydaymax haha. Thanks. will try this one.

Actually I think the previous script was right.
I need only one timestep which shows the maximum value of solar radiation per location that have been obtained any day of this 20 year period. so timmax looks more reasonable than ydaymax as far as the results i get.

Ok, I need now some help with this.
I want to create a file containing 365 timesteps, with the maximum daily solar radiation per day. This will allow me to see what sort of maximum values I could have any day of the year. I have a file of 20y daily means.
