6 天之前 · The rates at which rain, snow, or other forms of precipitation fall are of great interest to researchers, decision-makers, and planners alike as they seek to understand the impact of their accumulation. To aid them, NASA collects enormous amounts of data from ground and satellite instruments suitable for analyzing precipitation rates.

2020年11月4日 · Together, these instruments make up the joint NASA/Japan Aerospace Exploration Agency (JAXA) Global Precipitation Measurement mission. "Most of the satellites contributing to GPM aren’t precipitation satellites, per se," said George Huffman, who is deputy project scientist for GPM.

2021年4月19日 · The Core satellite was designed to sense a wide range of precipitation—such as drizzle, rain, snow and sleet—including rain and snow influenced by terrain. The meteorological phenomenon, called orographic precipitation, is McMurdie’s bailiwick.

The suite of current Global Precipitation Climatology Project (GPCP) precipitation products (Version 2) based on global observational data has become a science community standard, having been used in over 2500 journal articles.

2025年1月17日 · GPM GV provides ground and airborne precipitation datasets supporting physical validation of satellite-based precipitation retrieval algorithms. NASA's Global Hydrometeorology Resource Center DAAC ( GHRC DAAC ) works with the GPM GV Science Manager to support the following GPM GV physical process studies, which rely on targeted …

NASA's Goddard Earth Sciences Data and Information Services Center provides access to a wide range of global climate data, concentrated primarily in the areas of atmospheric composition, atmospheric dynamics, global precipitation, and solar irradiance.

2025年1月17日 · NASA’s Earth observation data useful for the study of precipitation include precipitation rates, rainfall estimates, and total precipitation. Both historical and near real-time data are available. These data products help scientists understand important topics such as natural disasters, weather, disease spread, agriculture, and air quality.

By providing next-generation global observations of rain and snow, NASA's Global Precipitation Measurement (GPM) platform helps researchers better understand Earth's water and energy cycles and forecast extreme events that cause natural hazards and disasters.

2014年4月30日 · This dataset contains the values for the time period of the IPHEx campaign from April 30, 2015 to June 17, 2015. The IPHEx campaign was designed to characterize warm season orographic precipitation regimes and determine the relationship between precipitation regimes and hydrologic processes in regions of complex terrain.

6 天之前 · Ground-based weather radars help determine where snow/precipitation is occurring and how intense it is falling over different areas. Several other instruments are used to study the size, shape and structure of snow particles (disdrometers, Precipitation Video Imagers and particle probes), snow depth (snow tubes), and the water content ...
