Eyes on Earth Episode 76 – ECOSTRESS and Disease Risk

Spaceborne sensors orbit hundreds of miles over our heads. Even the most advanced among them struggle to capture high-resolution imagery of individual human beings. Mosquitos, of course, are far smaller than we are. Clearly, sensors on a satellite or space station can’t see them. Even so, these sensors can gather a host of information that helps to understand the movements and behaviors of these pesky little disease vectors, which are responsible for at least a million deaths a year. Mosquitos are more active under certain environmental conditions, for example, and those conditions can be tracked at wide scales from above. Changes to the land’s surface can also make it easier for mosquitos to proliferate. On this episode of Eyes on Earth, we learn how a sensor onboard the International Space Station was used to calculate West Nile virus risk in California’s San Joaquin River Valley.
