The 10-member ensemble 4D-Var system used in ERA5 provides estimates of uncertainties in the data. where Tf is 273.16âK. This is better reflected in ERA5 than in ERA-Interim, as confirmed by a comparison with radiosonde observations (not shown). Tao, J., Koster, R. D., Reichle, R. H., Forman, B. Many studies have been based on low resolution reanalysis data that cannot allow a detailed description of the variability induced by local conditions. Figure 7 shows the point-wise linear trend in surface temperature between 1979 and 2018 from ERA5 in the Arctic region. stand-alone experiments, Clim. Alternatively, users can perform simple operations on the data (calculations, plotting, etc.) temperatures, J. Atmos.
This is illustrated in Figure 3, which shows the evolution of sub-daily ensemble spread for upper-air temperature averaged over the months March to May for particular years.

The Python script for downloading ERA5-Land is developed and provided through an application programming interface (API) request by ECMWF Climate Data Store (CDS) service and is available from the Supplement. of wind climate projection spread that derives from the specific AOGCM and RCM used in the downscaling. This multiplies the data volume, but it means you can use the spread between the ensemble members to get an estimate. Each monthly anomaly was computed by removing the 1981–2010 mean for the corresponding month. There has also been a marked increase in the number of other satellite observations assimilated, notably GNSS-Radio Occultation bending angles in large quantities from 2006, scatterometer ocean vector wind and altimeter wave height data (both from 1991), and Level-2 ozone products.
