Measures Raindrop Sizes From Space
Not all raindrops are created equal. The size of falling raindrops depends on several factors, including where the cloud producing the drops is located on the globe and where the drops originate in the cloud. For the first time, scientists have three-dimensional snapshots of raindrops and snowflakes around the world from space, thanks to the joint NASA and Japan Aerospace Exploration Agency Global Precipitation Measurement (GPM) mission. With the new global data on raindrop and snowflake sizes this mission provides, scientists can improve rainfall estimates from satellite data and in numerical...

OLYMPEX Successfully Grabs the Rains
NASA has finished its campaign to study extreme rain, snow and winds of the Olympic National Forest. Scientists Walt Petersen of NASA Marshall and Robert Houze of the University of Washington narrate this inside look at the Olympic Mountain Experiment (OLYMPEX) field campaign. During the campaign, NASA and its partners gathered precipitation data through both ground and airborne instruments around the Olympic Peninsula in Washington State. They measured the abundance and variety of precipitation including light rain, heavy thunderstorms, and snowfall in the coastal forest. The data collected...
