What's the result of add two .nc files with different time length?
Added by hongyi yan almost 4 years ago
Now I'm using HadCRUT data to calculate global warming rate...
It has two files. One is anomaly data series, with 2042 months data, and a mean referrence data with only 12 months long.
I use cdo add operator to get real temperature data, and it runs successfully.
The two data have different time length, what does the result of output .nc file mean?
A B
1+1
2+2
3+3
4+4
5+5
6+6
7+7
8+8
9+9
10+10
11+11
12+12
13+1
14+2
...
like this? or another way to add two data?

hi!
such an operation is not permitted. inputs have to have the same number of timesteps, or the seconds has to have only one.

Thanks!
now I have another question, how can I change the mean referrence data with only 12 months long to 2042 months long, a repeat series？

you might check the duplicate operator then. it will repeat the timeseries as often as you like.
