What is ERA Interim data?

ERA-Interim is a global reanalysis of recorded climate observations over the past 3.5 decades. It is presented as a gridded data set at approximately 0.7 degrees spatial resolution, and 37 atmospheric levels. ERA-Interim is produced by the European Centre for Medium-Range Weather Forecasts (ECMWF).

How do I download era interim daily data?

What does ERA stand for ECMWF?

Abstract. ERA-Interim is the latest European Centre for Medium-Range Weather Forecasts (ECMWF) global atmospheric reanalysis of the period 1989 to August 2019. This follows on from the ERA-15 and ERA-40 re-analysis projects. The dataset includes data on surface, PV, potential temperature and pressure surfaces.

What are the changes from era interim to ERA5?

ERA-Interim contains about 100 parameters on surface and single level alone, plus parameters on other level types. ERA5 contains over 240 parameters on surface and single level alone, plus parameters on other level types.

What is a climate reanalysis?

What is climate reanalysis? A climate reanalysis gives a numerical description of the recent climate, produced by combining models with observations. Climate reanalyses generate large datasets that can take up several petabytes of space, and are best processed with cloud-based tools, to avoid large download volumes.

How do I get Ecmwf data?

Commercial organisations can obtain a licence for commercial use of ECMWF forecast products and services. You can explore the datasets that are made available under licence, including those in the operational archive, and buy an archive data licence to download data using the Web API services.

What is the resolution of ERA5?

ERA5 data will be at a much higher resolution than ERA-Interim: hourly analysis fields will be available at a horizontal resolution of 31 km on 137 levels, from the surface up to 0.01 hPa (around 80 km).

What does ERA stand for in ERA5?

How accurate is ECMWF?

Checking up on global weather model skill w/ECMWF, NOAA GFS, and Canadian GEM. The verification numbers show the European is still the best model at five days out. Over the past 90 days, the European Model has averaged an accuracy correlation of 0.929. That’s pretty good at five days in the future.
