Filters
Here are some filters that are useful for manipulating data. There are actually many more available, but they have to be entered manually. See Ingrid Function Documentation for more information.- Monthly Climatology calculates a monthly climatology by averaging over all years.
- anomalies calculates the difference between the (above) monthly climatology and the original data.
- Integrate along X P T
- Differentiate along X P T
- Take differences along X P T
RMS (root mean square with mean *not* removed) over X P T | X P X T P T | X P T |
RMSA (root mean square with mean removed) over X P T | X P X T P T | X P T |
