The ERA5 global reanalysis

Abstract Within the Copernicus Climate Change Service (C3S), ECMWF is producing the ERA5 reanalysis which, once completed, will embody a detailed record of the global atmosphere...

The ERA‐Interim reanalysis: configuration and performance of the data assimilation system

Abstract ERA‐Interim is the latest global atmospheric reanalysis produced by the European Centre for Medium‐Range Weather Forecasts (ECMWF). The ERA‐Interim project was conducte...

ERA5-Land: a state-of-the-art global reanalysis dataset for land applications

Abstract. Framed within the Copernicus Climate Change Service (C3S) of the European Commission, the European Centre for Medium-Range Weather Forecasts (ECMWF) is producing an en...

Evolution of anthropogenic and biomass burning emissions of air pollutants at global and regional scales during the 1980–2010 period

Variational bias correction of satellite radiance data in the ERA‐Interim reanalysis

Abstract This article describes the performance of the variational bias correction system for satellite radiance data in ERA‐Interim, and considers implications for the represen...

The parametrization of surface fluxes in large‐scale models under free convection

Abstract This paper investigates the idea of formulating free convection in large‐scale models as a special case of forced convection. In free convection, the wind speed in the ...

Atmospheric conservation properties in ERA‐Interim

Abstract We study the global atmospheric budgets of mass, moisture, energy and angular momentum in the latest reanalysis from the European Centre for Medium‐Range Weather Foreca...

Data assimilation in atmospheric chemistry models: current status and future prospects for coupled chemistry meteorology models

Abstract. Data assimilation is used in atmospheric chemistry models to improve air quality forecasts, construct re-analyses of three-dimensional chemical (including aerosol) con...

Direct 4D-Var assimilation of all-sky radiances. Part I: Implementation

This article describes a new radiance-assimilation scheme for microwave-imager observations, which unifies the treatment of clear-sky, cloudy and precipitation-affected situatio...

Estimates of aerosol radiative forcing from the MACC re-analysis

Abstract. The European Centre for Medium-range Weather Forecast (ECMWF) provides an aerosol re-analysis starting from year 2003 for the Monitoring Atmospheric Composition and Cl...
