Aura (Latin for breeze) was launched July 15, 2004. Aura is part of the Earth Science Projects Division, a program dedicated to monitoring the complex interactions that affect the globe using NASA satellites and data systems. Aura's four instruments study the atmosphere's chemistry and dynamics. The satellite's measurements will enable scientists to investigate questions about ozone trends, air quality changes, and their linkage to climate change.
NOAA’s Geostationary Extended Observations (GeoXO) satellite system will expand observations of Earth that the GOES-R Series currently provides from geostationary orbit. The information that GeoXO supplies will address emerging environmental issues and challenges regarding weather, the ocean, and the climate that threaten the security and well-being of everyone in the Western Hemisphere. NOAA expects that GeoXO will begin operating in the early 2030s as the GOES-R Series nears the end of its operational lifetime.
The restructured Joint Polar Satellite System (formerly -- National Polar-orbiting Environmental Satellite System (NPOESS)), will address NOAA’s requirements to provide global environmental data necessary for NOAA’s missions to monitor the earth, manage resources, support the Nation’s economy, and protect lives and property. source: NOAA
The National Polar-orbiting Partnership (NPP) is a joint mission to extend key measurements in support of long-term monitoring of climate trends and of global biological productivity.
The instruments aboard NOAA’s Suomi NPP bridge some of the observational capabilities from NASA Aura, launched in 2004, to the other satellite instruments in NOAA’s Joint Polar Satellite System (JPSS), which includes two satellites yet to be launched.
