STRIVE Science Focus (IMAGE) University of Washington Caption The STRIVE project proposes a new, high-tech satellite to observe the lower two layers of the atmosphere, between 3 and 40 miles (5 and 70 kilometers) elevation. Human and natural emissions first enter the troposphere (white) layer enveloping the Earth. The stratosphere (blue) above contains the UV-blocking ozone layer. STRIVE would track both atmospheric layers, as well as the atmospheric chemistry, circulation and climate processes happening at the interface.
