Description: 

BIOMASS is a polarimetric P-band (435 MHz) synthetic aperture radar (SAR) in a dawn-dusk low Earth orbit. Its principal objective is to measure biomass content and biomass change in all the Earth’s forests. The mission launch is envisaged around 2020, for five-year duration. The ionosphere introduces Faraday rotation and scintillations on every pulse emitted by low- frequency SAR, impacting the quality of the imaging. Some of these effects are due to Total Electron Content (TEC) and its gradients along the propagation path. To support the Biomass operations, an accurate assessment of the ionosphere morphology and dynamics is necessary, especially in the equatorial and tropical regions.
