Gridded climatology data
References & Guides
Overview
The tables below detail the types of gridded data available for purchase. Metadata for each grid type is linked from the name of the element. For further information about the grids, including grid coverage, output formats and co-ordinate system, see Gridded climate data.
Average and climatological data
These grids contain data which have been averaged or analysed. For example, mean annual rainfall or heating degree days. These grids are available as annual averages or as monthly averages (with the exception of tropical cyclones, thunder days and lightning these elements are only available as annual grids).
