2025年1月23日 · 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.

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.

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.

Conventional means for measuring precipitation worldwide are generally inadequate due to spatial or temporal sampling issues. Consequently, satellite-based observations of precipitation are necessary to provide a global picture. Much effort has been expended in developing and refining precipitation techniques that can be applied globally.

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 …

The suite of current Global Precipitation Climatology Project (GPCP) precipitation products based on global observational data has become a science community standard, having been cited in over 4000 journal articles.

Building on algorithm development work funded through NASA's Precipitation Measurement Program, we propose to create a new rainfall and cloud water dataset using the latest version of the Goddard Profiling algorithm and based on a multi-decadal constellation of satellite radiometer data including Special Sensor Microwave Imager , Tropical ...

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.
