As a precursor to a revised extended reanalysis product to replace ERA-40, ECMWF released ERA-Interim, which covers the period from 1979 to 2019. A new reanalysis product ERA5 has more recently been released by ECMWF as part of Copernicus Climate Change Services. This product has higher spatial resolution (31 km) and covers the period from 1979 ...

ECMWF aims to provide accurate medium-range global weather forecasts out to 15 days and seasonal forecasts out to 12 months. [11] Its products are provided to the national weather services of its member states and co-operating states as a complement to their national short-range and climatological activities, and those national states use ECMWF's products for their own national duties, in ...
As detailed in Table 4 of Shen et al., these AI-driven models were trained with ERA5 reanalysis data and CMIP6 datasets and evaluated using a variety of metrics such as root mean square errors (RMSE), anomaly correlation coefficients (ACC), Continuous Ranked Probability Score (CRPS), Temporal Anomaly Correlation Coefficient (TCC), Ranked ...
Instead, they learn purely from data such as the ECMWF re-analysis ERA5. [82] These models typically require far less compute than physics-based models. [81] Microsoft's Aurora system offers global 10-day weather and 5-day air pollution (CO 2, NO, NO 2, SO 2, O
Re changes to vertical axis: version 16's source states: "Annual global mean temperatures expressed as a difference from pre-industrial conditions. Four different data sets are shown - HadCRUT, NOAAGlobalTemp, GISTEMP, and Berkeley Earth - as well as two reanalyses - ERA5 and JRA-55.
Analysis by the European Centre for Medium-Range Weather Forecasts (ECMWF) using ERA5 reanalysis data estimated the pressure of the cyclone as 900.7 mbar (26.60 inHg) early on 17 October while a paper published in Geophysical Research Letters in July 2023 got a minimum pressure of 899.91 mbar (26.574 inHg) the same day.

The Copernicus Climate Change Service [1] (abbreviated as C3S) is one of the six thematic services provided by the European Union's Copernicus Programme.The Copernicus Programme is managed by the European Commission and the C3S is implemented by the European Centre for Medium-Range Weather Forecasts (ECMWF).
