CMORPH precipitation
warning: irregular time axis CMORPH Version 1.0, RAW daily precip from 00Z-24Z averaged over 2x 2 grid boxes
X axis: whole world in 720 0.50° steps, first point at 0.25° E, last point at 359.75° E
Y axis: regular grid with 240 0.50° steps, first point at 59.75° S, last point at 59.75° N

1-daily data available from 01Jan1998 to 13Apr2024 ( 9620 times)
Variable prcp (daily precipitation) in mm/dy
Full metadata. The associated land/sea mask is available for some operations

Get grid points, average area or generate subset

Mask:	no mask   add a mask to the list
Latitude:	°N - °N
Longitude:	°E - °E
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
Considering:	everything land points sea points show/hide more only land points only sea points not land points not sea points
Units:	convert to mm/day leave in mm/dy

Create a field with lower time resolution

First fill missing data:	ignore, climatology, trend, persistence.
Then apply:	-day running mean with direction backward centred forward
Then apply new time scale:	keep same time scale annual (Jul-Jun) annual (Jan-Dec) biannual seasonal monthly 10-daily 5-daily
New variable:	mean sd sum sum above sum below number min time of min max time of max first time last time of precipitation
Minimum:	% valid data
Threshold:	no cut less than greater than mm/dy percentile normal 1971-2000

Create a field with lower spatial resolution

Average over blocks of longitude and latitude grid cells
