Summary: If you want to know how much rain fell yesterday, you can catch it and measure it. Water vapor? That's not so easy. Which is a problem if you want to know how quickly that rate is returning to the atmosphere. Water vapor is the single largest part of the water budget, but without space-based observations, it would be all but impossible to measure at wide scale. On this episode of Eyes on Earth, we learn how a sensor called ECOSTRESS helps improve the space-based measurement of evapotranspiration, or ET, which is the combined rate of evaporation from the Earth's surface and transpiration from plants.
