Access

NCEI manages an enormous collection of environmental data spanning a broad spectrum of scientific disciplines stored using a wide variety of archiving methods, naming conventions, file formats, governance strategies, organization methods, and storage infrastructure. NCEI develops software, APIs, visualization methods, and other services to enhance data data access, discovery, and interoperability.

Discovery Tools

NOAA OneStop

NOAA OneStop can be used to search for any NOAA data with a metadata record. It is an interoperable tool designed to explore data from across scientific disciplines, formats, time periods, and locations. OneStop’s wide range of filtering options can pinpoint specific collections or granules that may not be discoverable in other mediums.

Map Service Directories  

The REST services directory provide access to the GIS servers for NCEI map products. These servers contain service-level metadata, a variety of data visualization previews and download formats, and information for programmers and developers. 

Climate Data Online Web Services

Climate Data Online (CDO) offers web services that provide access to current data. This API is for developers looking to create their own scripts or programs that use the CDO database of weather and climate data. An access token is required to use the API, and each token will be limited to five requests per second and 10,000 requests per day.
