A NASA study has found a link between climate change effects on the productivity of grasslands and the growing number of bison in Yellowstone National Park. The data, which came from two NASA Earth science satellites, shows daily vegetation growth for the past 20 years and can be used to help forecast the movements of bison, aiding conservation eff

Australia has already been in a fiery situation for months so another fire starting in the Canberra region and spreading so quickly is nothing short of a tragedy for this country.

CERES

Clouds and the Earth’s Radiant Energy System

CERES measures reflected and emitted from the top of Earth's atmosphere.

There are two identical CERES instruments aboard Terra that measure the Earth’s total radiation budget and provide cloud property estimates that enable scientists to assess clouds’ roles in radiative fluxes from the surface to the top of the atmosphere. One CERES instrument operates in a cross-track scan mode and the other in a biaxial scan mode. The cross-track mode essentially continues the measurements of the Earth Radiation Budget Experiment (ERBE) and the Tropical Rainfall Measuring Mission (TRMM), while the biaxial scan mode provides new angular flux information that has improved the accuracy of angular models used to derive the Earth’s radiation balance.

Two CERES sensors also fly aboard Terra’s sister ship—Aqua.
