Data Collections

NOAA satellites observe the Earth from space, constantly scanning the planet to collect the most up-to-date data about the atmosphere, land, and oceans. This information is vital to our daily lives—and is in fact the basis for every weather forecast. From official comprehensive assessments of the environment to mapping the ocean floor from space, NESDIS science helps us better understand our complex planet.

Numerous offices within NESDIS help get this information from the satellites to all who need it every day.

NOAA Data Products

NOAA currently provides two approaches to enable searching vast data holdings: the traditional NOAA Data Catalog for all data, and the new NOAA OneStop catalog which initially includes only the archived datasets but will eventually replace the traditional catalog. Visit NOAA's Data Discovery Portal to learn more about these products.

How does data received from space turn into vital products and services used everyday across the country?

The NESDIS science enterprise transforms the “bits and bytes” received from satellites and other sources around the globe into environmental intelligence. From official comprehensive assessments of the environment to mapping the ocean floor from space, NESDIS science helps us better understand our complex planet.

National Centers for Environmental Information

All that data also needs to be stored somewhere. That’s where the National Centers for Environmental Information comes in. NCEI hosts and provides public access to one of the most significant archives for environmental data on Earth, consisting of more than 37 petabytes of comprehensive atmospheric, coastal, oceanic, and geophysical data. 

NCEI also provides authoritative assessments and research on the entire Earth system, from the bottom of the ocean to the surface of the sun. It also produces an increasing suite of products that integrate multiple sources of data both in space and on the ground to provide comprehensive atmospheric, oceanic, and geophysical environmental information.

Collecting an entire planet’s worth of information every day is a huge undertaking, and produces a massive amount of data. The satellites transmit all of these raw “bits and bytes” to NESDIS, where a team of scientists and supercomputers within its Center for Satellite Applications and Research (STAR) process it via complex algorithms so that it is easier for us to understand. Researchers at STAR then use the processed data to create state-of-the-art products and services that help decision-makers better inform the public and safeguard our environment. 

STAR scientists also lead efforts to develop, test, validate, and refine the science algorithms needed to enhance these data products as well as investigate how to improve sensor technology for future NOAA satellite missions.




NOAA DataFest is a month-long effort that aims to educate the public and inspire our colleagues at NOAA to learn more about NOAA data while celebrating its value, reliability, and accessibility. NOAA data covers a robust collection of scientific earth and environmental observations that is freely available to the scientific community and the public. Some of the DataFest activities include our NEDTalks series and an online Twitter chat known as Datapalooza.
