Since its launch in 1997, TRMM has provided critical precipitation measurements in the tropical and subtropical regions of our planet. The Precipitation Radar (PR) looked through the precipitation column, and provided new insights into tropical storm structure and intensification.

1997年11月27日 · The satellite uses several instruments to detect rainfall including radar, microwave imaging, and lightning sensors. Flying at a low orbital altitude of 240 miles (400 kilometers) TRMM's data collection of tropical precipitation helps improve our understanding about climate and weather.

A new data product merges data from the Tropical Rainfall Measuring Mission (TRMM) and the Global Precipitation Measurement (GPM) mission, giving meteorologists and researchers access to a 20-year precipitation record. How much rain and snow fall on Earth in any given year?

Using a network of satellites united by the GPM Core Observatory, GPM expands on the legacy of the Tropical Rainfall Measuring Mission (TRMM) by providing high quality estimates of Earth’s rain and snowfall every 30 minutes.

2015年4月10日 · Now, 17 years later, the TRMM mission has come to an end. NASA and the Japan Aerospace Exploration Agency (JAXA) stopped TRMM’s science operations and data collection on April 8 after the spacecraft depleted its fuel reserves.

Use of TRMM Precipitation Radar to address the problem of rain detection over the oceans in passive microwave measurements

NASA’s TRMM and GPM missions have collected rain and snowfall from space for more than 22 years (as of 2020), and for the first time in 2019 scientists can access PMM’s entire record as one unified data set.

This page provides a directory of download links, documentation, and other details about data products produced by NASA's Global Precipitation Measurement Mission (GPM) and Tropical Rainfall Measuring Mission (TRMM).

The Tropical Rainfall Measuring Mission’s (TRMM) Microwave Imager (TMI) is a passive microwave sensor designed to provide quantitative rainfall information over a wide swath under the TRMM satellite.

The Tropical Rainfall Measuring Mission (TRMM), launched in late 1997, is a joint mission between NASA and JAXA, the Japanese space agency. The first-time use of both active and passive microwave instruments and
