- 2nd generation reanalysis. Assimilates surface temperature from stations separately from the atmospheric analysis component using a univariate 2-dimensional optimal interpolation (2D-OI). Temperature from islands are not used because they are not representative at the grid scale of JRA-55. Determining whether an observation is from an island is based on the 0.25-degree resolution land cover data; consequently, observations from the coast are also excluded.
