The ERA-20C analysed surface parameters that are only available 6-hourly are those that are produced by the land-surface analysis scheme. Separate from the 4D-Var assimilation, the land-surface analysis scheme runs every 6 hours and only produces one temporal estimate at the centre of each 6-hour window. These 6-hourly parameters are:
