What it shows. Maps of what the atmosphere did over any period you choose: heights, winds, pressure, temperature, precipitation, moisture, OLR, SST and soil moisture as departures from a 1991–2020 daily climatology, or as period means.

Source. ERA5 daily means (00/06/12/18 UTC) on a 1.5° grid, 1959 → about five days ago. Days ERA5 has not reached are filled from ECMWF HRES open-data analyses, de-biased against ERA5 over recent overlap days, and are replaced by ERA5 automatically when it arrives.

σ and percentile modes compare this window with the same calendar window in every year of the base period.
