Missions: Earth System Science Pathfinder Program

Missions in the NASA Earth System Science Pathfinder (ESSP) Program are characterized by innovative design and relatively rapid implementation. These are focused missions that uniquely examine important components and physical processes within the global climate systems, including atmospheric CO2 distribution, sea surface salinity variation, mass water movement, and the vertical structure of clouds and aerosols.
