NCEI environmental data spans a broad spectrum of scientific disciplines, archive methods, naming conventions, file formats, and governance strategies. NCEI develops software, APIs, visualization methods, and other services to enhance 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.

Specs and Features

  • 104,000 collections
  • Over 3 million metadata granules
  • Search API can help narrow results, including filtering out records without data access
  • Robust, keyword enabled search interface
  • File filters to further narrow the granule download process

Data Access

The NCEI Data Access application offers a wide variety of download and subsetting options for a growing collection of environmental data. While current offerings are limited primarily to weather and climate information, the application has a data-agnostic infrastructure designed to accommodate a broad spectrum of observation formats from across science disciplines.

Specs and Features

  • Cloud ready APIs
  • Access to physical server and cloud based products
  • Direct download (csv, pdf, certified pdf, arcGIS/shapefile, bulk download, zip file)
  • Subsetting
  • Order fulfillment (through the online store)
  • Identifies certified data

Tools for Developers


Data Access APIs


Access and subset data based on a set of parameters to the v1 URL.



Discover datasets and data based on a set of parameters to the v1/datasets or v1/data URLs, respectively.



Discover metadata and attributes about datasets based on parameters of the /v3/datasets URL.



Retrieve information about previous orders based on a set of parameters to the /v1 or /v1/airs URLs, respectively.


Map Service Directories

The REST Services directory provide access to the GIS servers for NCEI map products. These 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.
