HadCRUT4.6 SST/T2m anom
HadCRUT4 near-surface temperature ensemble data - ensemble median
X axis: whole world in 72 5.00° steps, first point at 177.50° W, last point at 177.50° E
Y axis: regular grid with 36 5.00° steps, first point at 87.50° S, last point at 87.50° N

Monthly data available from Jan1850 to Dec2021 (2064 months)
Variable temperature_anomaly (near_surface_temperature_anomaly) in K
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
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
Considering:	everything land points sea points show/hide more only land points only sea points not land points not sea points
Units:	convert to Celsius leave in K

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 SST/T2m anom
Minimum:	% valid data
Threshold:	no cut less than greater than K percentile normal 1971-2000

Create a field with lower spatial resolution
