RBI - Radiation Budget Instrument

The Radiation Budget Instrument (RBI) is a scanning radiometer capable of measuring Earth’s reflected sunlight and emitted thermal radiation.


RBI will fly on the Joint Polar Satellite System 2 (JPSS-2) mission planned for launch in November 2021, and will extend the unique global climate measurements of the Earth’s radiation budget provided by the Clouds and the Earth’s Radiant Energy Systems (CERES) instruments since 1998.


Observations from RBI will help measure the effect of clouds on the Earth’s energy balance, which strongly influences both weather and climate.  Long-term satellite data from RBI will help scientists and researchers understand the links between the Earth’s incoming and outgoing energy, and properties of the atmosphere that affect it.  The data from RBI will provide fundamental inputs to extended range --10-day or longer -- weather forecasting, and also be used to develop a quantitative understanding of the links between Earth’s radiation budget and the properties of the atmosphere and surface that define that budget.


NASA's Langley Research Center in Hampton, Virginia, will administer the contract for the agency.
