Get grid points, average area or generate subset

Mask:	no mask   add a mask to the list
Latitude:	°N - °N
Longitude:	°E - °E
Year range:	-
Boundaries:	halfway grid points interpolated
Make:	average max min set of grid points subset of the field
Demand at least:	% valid points in this region

Create a field with lower time resolution

First fill missing data:	ignore, climatology, trend, persistence.
Then apply:	-month running mean with direction backward centred forward
Then apply new time scale:	keep same time scale annual (Jul-Jun) annual (Jan-Dec) biannual seasonal
New variable:	mean sd sum sum above sum below number min time of min max time of max first time last time of 20C isotherm
Minimum:	% valid data
Threshold:	no cut less than greater than m percentile normal 1971-2000

Create a field with lower spatial resolution

Average over blocks of longitude and latitude grid cells
