Welcome to NASA's EOSDIS

NASA's Earth Observing System Data and Information System (EOSDIS) is a key core
capability in NASA’s Earth Science Data Systems Program for archiving and
distributing Earth science data from multiple missions to users.

This bar indicates that you are within the EOSDIS enterprise which includes 12
science discipline-oriented Distributed Active Archive Centers (DAACs)
supporting diverse user communities in science research, applied science
research, applications, as well as the general interested public.

Find a DAAC / Other DAACs - Use these links to navigate to any of the 12 EOSDIS
DAACs.

ABOUT ASDC

THE MISSION OF THE ATMOSPHERIC SCIENCE DATA CENTER (ASDC) IS TO BE A LEADING
PROVIDER OF ATMOSPHERIC SCIENCE DATA PRODUCTS AND SERVICES TO THE SCIENCE
COMMUNITY THROUGH AGILITY, INNOVATION, AND TECHNICAL EXCELLENCE.
THE ASDC IS IN THE SCIENCE DIRECTORATE LOCATED AT THE NASA LANGLEY RESEARCH
CENTER (LARC), IN HAMPTON, VIRGINIA. THE SCIENCE DIRECTORATE'S CLIMATE SCIENCE
BRANCH, ATMOSPHERIC COMPOSITION BRANCH, AND CHEMISTRY AND DYNAMICS BRANCH WORK
WITH ASDC TO STUDY CHANGES IN THE EARTH AND ITS ATMOSPHERE. DATA PRODUCTS
TRANSLATE THOSE FINDINGS INTO MEANINGFUL KNOWLEDGE THAT INSPIRES ACTION BY
SCIENTISTS, EDUCATORS, DECISION MAKERS, AND THE PUBLIC. THE ASDC SUPPORTS OVER
60 PROJECTS AND PROVIDES ACCESS TO MORE THAN 1000 ARCHIVED COLLECTIONS. THESE
DATA SETS WERE CREATED FROM SATELLITE MEASUREMENTS, FIELD EXPERIMENTS, AND
MODELED DATA PRODUCTS. THE ASDC PROJECTS FOCUS ON THE EARTH SCIENCE DISCIPLINES
RADIATION BUDGET, CLOUDS, AEROSOLS, AND TROPOSPHERIC COMPOSITION.
