Earth observations are freely accessible to all, including NASA’s many partners in the U.S. and international organizations and governments, disaster-relief agencies worldwide, scientists from academia and the private sector, business, the military, and the general public.
These partners rely on NASA’s expertise in developing and launching missions, analyzing the data, and calibrating and validating results to ensure that the information is accurate.
Earth Observing System Data and Information System (EOSDIS) is a distributed system, with major facilities at Distributed Active Archive Centers (DAACs) throughout the United States. These institutions are custodians of Earth-observing mission data and ensure that data will be easily accessible to users.
The EOSDIS DAACs process, archive, document, and distribute data from NASA's past and current Earth-observing satellites and field measurement programs. Acting in concert, the DAACs provide reliable, robust services to users whose needs may cross the traditional boundaries of a science discipline, while continuing to support the particular needs of users within the discipline communities. User services include:
- Assistance in selecting and obtaining data.
- Access to data-handling and visualization tools.
- Notification of data-related news.
- Technical support and referrals.
EOSDIS is responsible for almost 22 petabytes (PB) of archived data and more than 10,000 unique research products, which are managed by NASA’s Earth Science Data and Information System (ESDIS) Project.
The volume of data in this vast archive is expected to grow significantly over the next several years, and may be almost 247 PB in size by 2025.
Worldview from NASA's EOSDIS provides the capability to interactively browse global, full-resolution satellite imagery and download the underlying data. Most of the 400+ available products are updated within three hours of observation, essentially showing the entire Earth as it looks "right now." This supports time-critical application areas such as wildfire management, air quality measurements and flood monitoring. Arctic and Antarctic views of several products are also available for a "full globe" perspective. Browsing on tablet and smartphone devices is generally supported for mobile access to the imagery.
NASA Earth Observatory shares images, stories and discoveries about the environment, Earth systems and climate that emerge from NASA research, including satellite missions, in-the-field research, and models. In addition to the Image of the Day and access to global maps, the Earth Observatory produces EO Kids, an online, hands-on science publication for kids age 9-14.
