NetCDF data files

The NetCDF data files are available using the 1961-90 reference period (to match HadEX, HadEX2 and the WMO climatology period for long-term assessments) and for some indices the 1981-2010 reference period.

The current version is 3.0.3 (16th December 2020). For full details see the Changelog.

These files contain the numbers of stations within the grid box as well as the number of stations within a DLS (Decorrelation Length Scale) from the grid box centre.
