Brief description of information provided

100 member realisations sampling the observational uncertainty model of HadCRUT4, an observational dataset of blended land air temperatures and sea surface temperatures. Data are in netcdf format for 1850-2014 period, given as anomalies with respect to 1961-1990 period. Measurement and sampling uncertainty ensemble created following technique described in Jones and Kennedy (2017). N.B. this is not a formal addition to the HadCRUT4 dataset product. Annual means created from monthly fields, requiring at least 8 months of non-missing data to be present to create annual mean at gridpoint.
