This February, a NASA-led research campaign called SnowEx kicked off in Colorado. The 5-year study will advance global measurements of how much snow is on the ground at any given time and how much liquid water is contained in that snow. The amount of water in snow plays a huge role in water availability for drinking water, agriculture, and hydropower.Teams of 50 researchers are stationed at Grand Mesa and Senator Beck Basin over a three-week period to measure snow using a variety of snow-sensing instruments and techniques. Ground measurements will allow the team to validate the remotely sensed measurements acquired by multiple sensors on the various aircraft.Data acquired from the SnowEx campaign will be stored at the National Snow and Ice Data Center in Boulder, Colorado, and will be available to anyone to order at no cost, as is the case with all NASA data.

NASA’s SnowEx ground and airborne campaign is a multiyear effort using a variety of techniques to study snow characteristics, and the team concluded their second year in March 2020. Not only is SnowEx learning valuable information about how snow properties change by terrain and season, but they are also testing the tools NASA will need to sample snow from space.

SnowEx is a NASA led multi-year research campaign to improve measurements of how much snow is on the ground at any given time and how much liquid water is contained in that snow.Five aircraft with a total of ten different sensors will participate in the SnowEx campaign. From a base of operations at Peterson Air Force Base, Colorado Springs, SnowEx will deploy a P-3 Orion aircraft operated by the Scientific Development Squadron ONE (VXS-1), based at Naval Air Station Patuxent River, Maryland. A King Air plane will fly out of Grand Junction, Colorado, while high-altitude NASA jets will fly from Johnson Space Center in Houston.The planes will carry passive and active microwave sensors that are good at measuring snow-water equivalent in dry snow, but are less optimal for measuring snow forests or light snow cover. The campaign will also deploy an airborne laser instrument to measure snow depth, and airborne sensors to measure surface temperature and reflected light from snow.Data acquired from the SnowEx campaign will be stored at the National Snow and Ice Data Center in Boulder, Colorado, and will be available to anyone to order at no cost, as is the case with all NASA data.For more information: https://www.nasa.gov/earthexpeditions ||

A group of scientists and pilots conducted a series of science flights over Western Colorado for a new five-year NASA-led airborne mission called SnowEx.SnowEx is exploring better ways to measuring how much water is stored in snow-covered regions with the goal of eventually creating a future snow satellite mission. More accurate snow measurements will help scientists and decisions-makers better understand our world’s water supply and better predict floods and droughts. Data acquired from the SnowEx campaign will be stored at the National Snow and Ice Data Center in Boulder, Colorado, and will be available to anyone to order at no cost, as is the case with all NASA data.For more information:NASA's SnowEx Challenges the Sensing Techniques...'Until They Break'NASA: Snow Science in Support of Our Nation's Water Supply ||

The Arctic Boreal Vulnerability Experiment, or ABoVE, is a NASA-led, 10-year field experiment designed to better understand the ecological and social consequences of environmental change in one of the most rapidly changing regions on Earth. Satellite, airborne, and ground observations across Alaska and Canada will help us better understand the local and regional effects of changing forests, permafrost, and ecosystems – and how these changes could ultimately affect people and places beyond the Arctic.

From November 10 through December 21, NASA and university scientists are taking to the field to study wet winter weather near Seattle, Washington. With weather radars, weather balloons, specialized ground instruments, and NASA's DC-8 flying laboratory, the science team will be verifying rain and snowfall observations made by the Global Precipitation Measurement (GPM) satellite mission on a NASA-led field campaign, The Olympic Mountain Experiment, or OLYMPEX.For more information: http://www.nasa.gov/feature/goddard/nasa-heads-to-pacific-northwest-for-field-campaign-to-measure-rain-and-snowfall ||

For six weeks in Ontario, Canada, scientists and engineers lead a field campaign to study the science and mechanics of falling snow. The datasets retrieved will be used to generate algorithms which translate what the GPM Core satellite "sees" into precipitation rates, including that of falling snow. Ground validation science manager Walt Petersen gives a summary of the GCPEx field campaign. Field campaigns are critical in improving satellite observations and precipitation measurements. ||

NASA is flying an airborne science laboratory through Canadian snowstorms for six weeks in support of a difficult task of the upcoming Global Precipitation Measurement (GPM) mission: measuring snowfall from space. GPM is an international satellite mission scheduled for launch in 2014 that will provide next-generation observations of worldwide rain and snow every three hours. It is the first precipitation mission designed to detect falling snow from space. NASA's DC-8 flying laboratory flew this flight path on Jan 19, 2012 in support of NASA's Global Precipitation Measurement Cold-season Precipitation Experiment (GCPEx) snow study. The GCPEx field campaign will help scientists match measurements of snow in the air and on the ground. ||
