| Abstract | This is the 2.1.0.2015p version of the HadISDH land data. The data are provided by the Met Office Hadley Centre. This version spans 1/1/1973 to 31/12/2015.
This version extends the 2.0.1.2014p version to the end of 2015. It includes a minor code change to the homogenisation software and some historical changes to the data due to source archive changes and minor changes to applied homogeneity adjustments due to sensitivity to both the historical changes. More information can be found in the HadISDH.v2.1.0.2015p_Update_Document (see Docs) and at http://hadisdh.blogspot.co.uk/2016/06/2015-update-for-hadisdh2102015p.html.
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.
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.

| Dataquality information | HadISDH, a global land surface humidity dataset is produced by the Met Office Hadley Centre in collaboration with Maynooth University, NOAA NCEI, NPL and CRU. 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. |
