Three components of the Earth system

The three selected Earth Explorer candidate missions missions that go foward to Feasibility Study are BIOMASS, CoReH₂O and PREMIER. Each proposes to look at a component of the Earth system.

BIOMASS aims to determine the distribution and temporal changes of forest biomass at a global scale. CoReH₂O aims to measure fresh water stored in snow on land surfaces and in snow accumulation on glaciers and ice sheets. PREMIER aims to quantify processes controlling global atmospheric composition in the mid- to upper-troposphere and lower stratosphere.
