New method efficiently estimates surface reflectivity from incoming sunlight bounced back by clouds
Capturing sunlight reflected off the Earth's surface and bounced off a cloud back to the Earth is an effective measure of surface reflectivity—or surface albedo, the measure of how mirror-like the Earth's ...
New research explains wintertime ozone pollution in Utah oil and gas fields
Chemicals released into the air by oil and gas exploration, extraction and related activities can spark reactions that lead to high levels of ozone in wintertime, high enough to exceed federal health standards, ...
