GraphEM-infilled HadCRUT4.6.0.0 January 1850 - December 2020

Here are the GraphEM-infilled HadCRUT4.6 surface temperature anomaly data. This interpolated dataset presents a spatially-complete, global surface temperature product dating back to 1850 AD. The procedure used to generate these data is described in Climate field completion via Markov random fields - Application to the HadCRUT4.6 temperature dataset (Vaccaro et al., 2021). Included are the GraphEM-infilled HadCRUT4.6 median on a 5° x 5° grid as well as monthly and annual global and hemispheric means. The raw HadCRUT4.6.0.0 median data has been updated to span through December 2020.
