U.K. Met Office Hadley Centre Global Sub-Daily Station Observations (HadISD)

The Hadley Centre at the U.K. Met Office has created a global sub-daily dataset of several station-observed climatological variables which is derived from and is a subset of the NCDC's Integrated Surface Database. Stations were selected for inclusion into the dataset based on length of the data reporting period and the frequency with which observations were reported. The data were then passed through a suite of automated quality-control tests to remove bad data. The current version presented here is HadISD.1.0.0.2011f, with data through the year 2011. A preliminary version which includes 2012 data (HadISD.1.0.0.2012p), is available from the HadISD web site. Once that version is made final, we will archive it here in the RDA.
