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. We also include the files which are in the "climdex" format to match those available at www.climdex.org.

The current version is 3.0.1 (28th September 2020). For full details see the Changelog.
