«We now have direct observations that seeding of certain clouds follows a pathway first theorized in the mid-20th century.» (sciencedaily.com)
Researchers improved modeling of cloud vertical structure by including certain cloud and precipitation variables to increase simulation accuracy (pnnl.gov)
In another study, PNNL researchers figured out how to calculate certain cloud properties by combining data collected from instruments on the ground rather than relying upon research aircraft that collect data as they fly. (pnnl.gov)
