It combines HadISDH.land.4.2.0.2019f and HadISDH.marine.1.0.0.2019f. These data are provided by the Met Office Hadley Centre. This version spans 1/1/1973 to 31/12/2019. The data are monthly gridded (5 degree by 5 degree) fields. 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 NetCDF format. This version is the first available. To keep informed about updates, news and announcements follow the HadOBS team on twitter @metofficeHadOBS.

It is based on the sub-daily station observations from HadISD (originally from ISD) and ship observations from ICOADS. It is passed to the BADC for archiving and distribution. Gridboxes containing both land and marine data are combined using a weighted average with a minimum and maximum weighting of 25% and 75% respectively.
