The data are provided by the Met Office Hadley Centre. This version spans 1/1/1973 to 31/12/2016. The data are monthly gridded (5 degree by 5 degree) and station products are available for temperature and six humidity variables: specific humidity (q), relative humidity (RH), dew point temperature (Td), wet bulb temperature (Tw), vapour pressure (e), dew point depression (DPD). Data are provided in either NetCDF or ASCII format. This version extends the 2.1.0.2015p version to the end of 2016 and constitutes a major update to HadISDH due to a major update of the source data HadISD. Improvements in this version include increased numbers of stations (~8000) and updated methodologies. Users are advised to read the update document in the docs section for full details. Uncertainty estimates are provided at the station and gridbox level covering station uncertainty (climatological, homogenisation and measurement uncertainty), gridbox spatial and temporal sampling uncertainty and combined station and sampling uncertainty. To keep up to date with updates, news and announcements follow the HadOBS team on twitter @metofficeHadOBS.

It is based on the quality controlled sub-daily HadISD from the Met Office Hadley Centre which is in turn based on the ISD dataset from NOAA's NCEI. It is passed to the BADC for archiving and distribution.
