The global land surface temperature databank contains monthly timescale mean, max, and min temperature for approximately 40,000 stations globally. It was developed as part of the International Surface Temperature Initiative. This is the global repository for all monthly timescale land surface observations from the 1800s to present and uses data deriving from sub-daily, daily, and monthly observations. It brings together data from more than 45 sources and is used in the creation of various integrated global temperature resources, most notably Global Historical Climatology Network Monthly (GHCN-M) v4. Daily Data is purposefully provided as raw, non-homogenized observations with no integrated quality control performed. Data are submitted as-is from the data provider to ensure absolute data integrity and visibility of the data.
