I´m working with CDO and I would like to get the maximum temperature from my file. The time data is different if I use the command cdo monmax infile outfile and cdo --timestat first monmax infile outfile

If i use cdo monmax infile outfile the timedata is: 2021-06-15 22:30:00 and if I use cdo --timestat first monmax infile outfile the timedata is: 2021-06-01 00:00:00

  • I am not sure what the problem is. `cdo --timestat first` will result in the first time step in the infile being used in the outfile, whereas not including `timestat` will just use the default time method. Why do you not expect them to be different? – Robert Wilson Apr 05 '23 at 07:48
  • hi, Robert is right, this is exactly the behaviour you expect, if you want to see how timestat_date works, I explain it at about minute=6 in this video : https://www.youtube.com/watch?v=pD1r12pklEo – ClimateUnboxed Apr 05 '23 at 08:03
  • Thanks to both of you, with your youtube video it´s already clearer to me. The thing is that I have three hours timesteps, so 22:30:00 seemed a strange result to me. – Alvaro Santos Apr 06 '23 at 08:14
  • If this is why it seemed strange, it would be better to say it in the question. We are not psychic ;) – Robert Wilson Apr 06 '23 at 11:11
  • that is probably precisely the mid point of the month calculated by cdo based on the 3 hourly steps. – ClimateUnboxed Apr 14 '23 at 07:03
