Libera
Libera
Extending the decades-long record of Earth's energy budget
The Libera mission will record how much energy leaves our planet’s atmosphere on a day-by-day basis providing crucial information about how Earth’s climate is evolving over time. The mission will maintain decades long data record of observation from NASA’s suite of Clouds and the Earth’s Radiant Energy System (CERES) instruments.

Libera will measure solar radiation with wavelengths between 0.3 and 5 microns reflected by the Earth system and infrared radiation with wavelengths between 5 and 50 microns emitted from the Earth system as it exits the top of the atmosphere. The sensor will also measure the total radiation leaving the Earth system at all wavelengths from 0.3 to 100 microns. An innovative additional “split shortwave” channel measuring radiation between 0.7 and 5 microns has been added to enable new Earth radiation budget science.
