Cloud Storage provides a variety of public datasets that can be accessed by
the community and integrated into their applications. Google pays for
the hosting of these datasets, providing public access to the data via tools
such as the Google Cloud console and Google Cloud CLI.

## Available public datasets on Cloud Storage

- [Analysis-Ready, Cloud Optimized (ARCO) ERA5](https://console.cloud.google.com/marketplace/product/bigquery-public-data/arco-era5): Datasets from the European
  Centre for Medium-Range Weather Forecasts (ECMWF) that provide hourly
  estimates of atmospheric, land, and oceanic climate variables. Data available
  from 1979 to the present.

- [Sentinel-2](https://console.cloud.google.com/marketplace/product/esa-public-data/sentinel2): A satellite image dataset from the European Space Agency
  (ESA) that includes multispectral images of the Earth's land surface, with a
  resolution of 10--60 meters per pixel, from 2015 through the present.

  collected from a network of 160 high-resolution Doppler weather radars
  operated by the NOAA National Weather Service (NWS), the Federal Aviation
  Administration (FAA), and the U.S. Air Force (USAF).

## How to use public datasets on Cloud Storage

Cloud Storage is a powerful, simple, and cost effective object storage
service. The public datasets are already hosted and available for users to
access for free. You can [access public data](https://docs.cloud.google.com/storage/docs/access-public-data.md.txt) with tools such as the
[Google Cloud console](https://docs.cloud.google.com/storage/docs/discover-object-storage-console.md.txt) and [Google Cloud CLI](https://docs.cloud.google.com/storage/docs/discover-object-storage-gcloud.md.txt), or with a Cloud Storage API
link.

The Google Cloud console and gcloud CLI require you to authenticate
to access public data. The user account that you authenticate with does not have
to be associated with the project that contains the public data, nor does it
need to be signed up for the Cloud Storage service.

By contrast, accessing public data with a Cloud Storage API link does
not require authentication. This method is suited for general-purpose links
to publicly shared data. For example, API links can be used in a web
page or downloaded with a command-line tool such as cURL.
