HadISDH data download - version 3.0.0.2016p


If download speeds or limits are an issue, or if you require individual stations in ASCII please contact us and we will investigate alternative solutions.


The current version of HadISDH is 3.0.0.2016p. For previous versions please contact the dataset maintainers.


NetCDF gridded files contain fields on 5° by 5° resolution from -177.5° W/87.5° N to 177.5° E/-87.5° S.


NetCDF station files contain monthly time series from January 1973 to December 2016.


Missing data are represented by -1e30.


Variables are described below.


The ASCII good station list file contains a WMO identifier (digits 0-5 (a6)), a WBAN identifier (digits 6-10 (a5)), a latitude (digits 11-19 (f9.4)), a longitude (digits 20-29 (f10.4)), an elevation in metres (digits 29-35 (f7.1)), space, a country ID (digits 37-39 (a2)), space, and a name (digits 41-72 (a32)).


The ASCII list of stations with subzero and supersaturated issues contain a WMO identifier (digits 0-5 (a6)), a WBAN identifier (digits 6-10 (a5)), the total number of affected months (digits 28-30 (i3)) and the total number of non-missing months (digits 32-34 (i3)).


The ASCII version of the gridded data lists each month in turn with 72 columns of longitude (-177.5 to 177.5 grid cell centres) and 36 rows of latitude (-87.5 to 87.5 grid cell centres). The longitudes and latitudes are listed at file end.
