Earth Science and Applications from Space 22 SCLP Snow and Cold Land Processes Launch: 2016–2020 Mission size: Medium Orbit: LEO, SSO Agency: NASA Estimated cost: $500 million Areas of interest: Water Instruments: Ku- and X-band radars,  K- and Ka-band radiometers Benefits: Improved management of water resources in snowmelt-dominated river basins Assessment of the risk of snowmelt-induced floods and flows of debris Predictions of the impact of climate change on seasonal snowpacks Seasonal snowpacks and glaciers provide water for one-sixth of the world’s population and affect weather and climate on local, regional, and global scales. Climate change seriously threatens the global abundance and timing of snow. Runoff from western U.S. snowfall now peaks several weeks earlier in the spring than it did in the 1950s. Despite the importance of snow to society, there are major gaps in snow-cover observations globally. Scientists and water resource managers need to know where and how much snow has fallen, how much water it holds, and how fast it is melting. Through a combination of active and passive microwave sensors, SCLP will provide a detailed and frequently updated record of snow cover. A pair of synthetic aperture radars will be able to characterize both deep and shallow snowpacks. A dual- frequency passive radiometer will provide additional detail and allow for comparison with snow data from similar sensors on other platforms. The mission will provide observations on two needed timescales: 15-day observation intervals will capture sea- sonal change, and more frequent (3- to 6-day) observations will track the effects of individual weather events. The passive microwave component of SCLP could provide a source of interim data to users affected by the removal of the passive microwave instrument from the first National Polar-orbiting Operational Environmental Satellite System (NPOESS) platform.

Satellite Observations to Benefit Science and Society: Recommended Missions for the Next Decade brings the next ten years into focus for the Earth and environmental science community with a prioritized agenda of space programs, missions, and supporting activities that will best serve scientists in the next decade. These missions will address a broad range of societal needs, such as more reliable weather forecasts, early earthquake warnings, and improved pollution management, benefiting both scientific discovery and the health and well-being of society.

Based on the 2007 book, Earth Science and Applications from Space: National Imperatives for the Next Decade and Beyond, this book explores each of the seventeen recommended missions in detail, identifying launch dates, responsible agencies, estimated cost, scientific and public benefits, and more. Printed entirely in color, the book features rich photographs and illustrations, tables, and graphs that will keep the attention of scientists and non-scientists alike.
