What does ERA5 mean?
ECMWF Reanalysis 5th Generation
Acronym ERA5 Name ECMWF Reanalysis 5th Generation Description. ERA5 is the fifth generation of ECMWF atmospheric reanalyses of the global climate (http://climate.copernicus.eu/products/climate-reanalysis ).
What is ERA5 reanalysis?
ERA5 is the fifth generation ECMWF atmospheric reanalysis of the global climate covering the period from January 1950 to present. ERA5 is produced by the Copernicus Climate Change Service (C3S) at ECMWF. ERA5 provides hourly estimates of a large number of atmospheric, land and oceanic climate variables.

What is the JRA 55 project?
JRA-55 – the Japanese 55-year Reanalysis The second Japanese reanalysis project conducted by the Japan Meteorological Agency (JMA), which cover the period from 1958 onward.
Is GFS or euro more accurate?
The upgrades come as the European Centre for Medium-Range Weather Forecasts’ model, or colloquially known in the weather community as “the Euro,” has fame for being more accurate than the American GFS (a little more detail can be found here).
How do you install and use CDS API on Windows?
Step-by-step guide
- Login to CDS (or Login to ADS)
- Copy a 2 line code, which shows a url and your own uid:API key details as followed:
- Paste the 2 line code into a %USERPROFILE%\.
- Install the CDS API client by running the following command in a Command Prompt window:
How do I download Ecmwf data in Python?
3. Download a data sample
- Go to ECMWF Web User Interface for ERA-Interim.
- Make sure you are logged in with your ECMWF user ID (top right of the page)
- In the left hand menu select if you want daily or monthly data, and surface, pressure levels or model levels.
- Select the time period you want to download.
What is a reanalysis dataset?
Reanalysis data provide the most complete picture currently possible of past weather and climate. They are a blend of observations with past short-range weather forecasts rerun with modern weather forecasting models. They are globally complete and consistent in time and are sometimes referred to as ‘maps without gaps’.
What does time and date mean in ERA5?
In the ERA5 data archive, for forecasts, ‘time’ (and date) refers to the initialization time. Each forecast computes the future atmospheric conditions, and at certain “points”, or “steps”, during this computation the data is post-processed, and stored in the ERA5 data archive.
When is the initialization time for ERA5 forecasts?
In ERA5 a new forecast is computed twice a day, with initialization times of 06:00 and 18:00 UTC. In the ERA5 data archive, for forecasts, ‘time’ (and date) refers to the initialization time. I didn’t anything that explicitly says they used UTC throughout, but the documentation is hundreds of pages long and I didn’t read it word-for-word.
How often does ERA5 land data come out?
The data are available at a sub-daily and monthly frequencies. For convention and consistency with the previous ERA-Interim/Land dataset, the data parameters are labelled as analyses and short (24 hour) forecasts initialised once daily from analyses at 00 UTC.
Which is the first segment of the ERA5 dataset?
A first segment of the ERA5 dataset is now available for public use (1979 to within 3 months of real time). ERA5 provides hourly estimates of a large number of atmospheric, land and oceanic climate variables. The data cover the Earth on a 30km grid and resolve the atmosphere using 137 levels from the surface up to a height of 80km.
