HadISDH blend: gridded global monthly ocean surface humidity data version 1.0.0.2019f
This is the 1.0.0.2019f version of the HadISDH (Integrated Surface Database Humidity) blend data. 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.

- Statement
- HadISDH.blend is a global land (~2 m) and ocean (~10 m) surface humidity dataset and is produced by the Met Office Hadley Centre in collaboration with CRU, Maynooth University, NPL, NOAA-NCEI and NOC. 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.
