How do I download data from ERA5?

ERA5 data can be downloaded through the CDS either via the CDS web interface or programmatically using the CDS API service. Any data in the CDS catalogue can be accessed in these two ways. And since such data is kept online, access is usually fast. Some parts of the ERA5 dataset are not listed in the CDS catalogue.
 

What is Ecmwf ERA5?

ERA5 Daily Aggregates – Latest Climate Reanalysis Produced by ECMWF / Copernicus Climate Change Service. ERA5 is the fifth generation ECMWF atmospheric reanalysis of the global climate. Reanalysis combines model data with observations from across the world into a globally complete and consistent dataset.

What is ERA5 land?

ERA5-Land is a reanalysis dataset providing a consistent view of the evolution of land variables over several decades at an enhanced resolution compared to ERA5. ERA5-Land has been produced by replaying the land component of the ECMWF ERA5 climate reanalysis.
 

Is ERA5 data free?

About the dataset
Use: Use of ERA5 data is free of charge, worldwide, non-exclusive, royalty-free and perpetual. All users of Copernicus Products must provide clear and visible attribution to the Copernicus program.

What is ERA5 reanalysis data?

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.

How do I access my ECMWF data?

Access to archive datasets

  1. ECMWF computers.
  2. The Web API service (using supported Python client software)
  3. Web interfaces where you can explore data, configure your data request, check availability and size, generate download request scripts, and download the data in GRIB/NetCDF* ECMWF – MARS Catalogue 🔒

How is ERA5 data collected?

This principle, called data assimilation, is based on the method used by numerical weather prediction centres, where every so many hours (12 hours at ECMWF) a previous forecast is combined with newly available observations in an optimal way to produce a new best estimate of the state of the atmosphere, called analysis,
 

How do I download ECMWF data?

3. Download a data sample

  1. Go to ECMWF Web User Interface for ERA-Interim.
  2. Make sure you are logged in with your ECMWF user ID (top right of the page)
  3. In the left hand menu select if you want daily or monthly data, and surface, pressure levels or model levels.
  4. Select the time period you want to download.

How do I download data from NOAA?

Downloading weather from NOAA website
Select Weather Observation Type/Dataset and select Daily Summaries. Select Date Range using the calendar button (Be sure to get daily weather data for 365/366 days of the year). Search for and choose the appropriate search type you will be using (typically we select Stations).
