Climate Change: Vital Signs of the Planet: NASA's ECOSTRESS will monitor plant health
A new space-based instrument to study how effectively plants use water is being developed at NASA's Jet Propulsion Laboratory, Pasadena, California. The instrument, called the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS), will monitor one of the most basic processes in living plants: the loss of water through the tiny pores in leaves.
