I would like to know how to download ERA5 data via R currently ---

this forum post describes how R can be used to access ERA5 data from the current CDS. Please note the recommended way to access ERA5 data is via the CDS API > [@Download CDS ERA5 data using R](https://prod.ecmwf-forum-prod.compute.cci2.ecmwf.int/t/download-cds-era5-data-using-r/1365): > > Users can download CDS data using the [ecmwfr](https://cran.r-project.org/web/packages/ecmwfr/index.html) package in R with “cds” as the "service" although it is not supported by C3S. In the examples below, "KEY" and "UID" are your CDS API key and UID respectively. Please have a look at the following example to download ERA5 2m temperature for a selected area in netCDF format:  library(ecmwfr)   cds.key \<- "Insert\_your\_CDS\_API\_KEY\_here" wf\_set\_key(user = "Insert\_your\_CDS\_UID\_here", key = cds.key, service = "cds") … ---

Hi @hejie_wang, I’m the developer of the R package and you can find extensive documentation on the github pages website. > **[Interface to ECMWF and CDS Data Web Services](https://bluegreen-labs.github.io/ecmwfr/)** > > Programmatic interface to the European Centre for Medium-Range Weather Forecasts dataset web services (ECMWF; ) and Copernicus's Climate Data Store (CDS; ). Allows for easy downloads of weather forecasts and climate reanalysis data in R. A note of caution, as it stands due to the lack of transparency in the API structure of the new C/ADS-beta I’m unsure I can keep support going. This is a shame as this will pull with it other downstream dependent innovative R packages (including peer reviewed scientific work [Radware Bot Manager Captcha](https://iopscience.iop.org/article/10.1088/1748-9326/ac48b3)). @Kevin_Marsh I hope I (and others) can get more information to keep the R ecosystem alive without resorting to clunky solutions such as reticulate, i.e. running a python VM in R. The NASA Appeears project has done this nicely, providing true open source API support, to their API. ---

@hejie_wang Update on the status of things. The package has been updated to work with the current API. > **[Interface to ECMWF and CDS Data Web Services](https://bluegreen-labs.github.io/ecmwfr/)** > > Programmatic interface to the European Centre for Medium-Range Weather Forecasts dataset web services (ECMWF; ) and Copernicus's Data Stores. Allows for easy downloads of weather forecasts and climate reanalysis data in R. Data stores covered include... You can now use R again to download data from CDS, ADS and emergency services.
