UKCP09: 25 km gridded data

The data files are obtained by clicking on the links in the table below. The first link is to a zip file containing 17 text files (one for each month, season and the year as a whole). The individual grids are named according to the following convention:

vvvvvv_1961-1990_LTA_25km_ppp.txt

where 'vvvvvv' is the variable name and 'ppp' is the averaging period, i.e. jan, feb, mar, etc. (for individual months), djf (winter), mam (spring), jja (summer), son (autumn) or ann (for the annual average).

The second link is to a single netCDF file that contains the data for all months, seasons and the year as a whole.
