Rainfall Accumulation Across the United States (1/1/2015 - 7/16/2015)

This visualization shows heavy rainfall throughout Northern Texas and across Oklahoma from January 1, 2015 through July 16, 2015 as well as the drought in Southern California during that same time period.

NASA's Global Precipitation Measurement (GPM) mission launched on Feb. 27, 2014. It is a collaboration between NASA and the Japan Aerospace Exploration Agency and acts as the standard to unify precipitation measurements from a network of 12 satellites. The result is IMERG, which combines data from all 12 satellites into a single, seamless map. The map covers more of the globe than any...

GPM Dissects Typhoon Hagupit

On December 5, 2014 (1032 UTC) the Global Precipitation Measurement (GPM) mission's Core Observatory flew over Typhoon Hagupit as it headed towards the Philippines. A few hours later at 1500 UTC (10 a.m. EST), Super Typhoon Hagupit's maximum sustained winds were near 130 knots (149.6 mph/241 kph), down from 150 knots (172 mph/277.8 kph). Typhoon-force winds extend out 40 nautical miles (46 miles/74 km) from the center, while tropical-storm-force winds extend out to 120 miles (138 miles/222 km).

The GPM Core Observatory carries two instruments that show the location and intensity of rain and...

Accumulated Precipitation from the IMERG Global Precipitation Data

The global IMERG precipitation dataset provides rainfall rates for the entire world every thirty minutes.  Using this dataset, it is possible to calculate the amount of accumulated rainfall for any region over a period of time.  This visualization shows the accumulation of rainfall across the globe August 4, 2014 through August 10, 2014.  In addition to the dramatic accumulation near Japan due to Typhoon Halong and the track of Hurricane Bertha off the eastern coast of the United States, it is also possible to see a rare August storm over the North Sea near Europe, the origins of Hurricane...

GPM Explores Typhoon Vongfong

On October 9, 2014 (0248 UTC) the Global Precipitation Measurement (GPM) mission's Core Observatory flew over Typhoon Vongfong as it headed towards Japan. At this point, the storm had weakened to a category 4 typhoon with maximum sustained winds at 150 miles per hour (mph), down form a category 5 typhoon on October 8th. This visualization first reveals a swath of GPM/GMI precipitation rates over Typhoon Vongfong.  As the camera moves in on the storm, DPR's volumetric view of the storm is revealed.  A slicing plane moves across the volume to display precipitation rates throughout the storm...

IMERG Accumulated Precipitation of Three Hurricanes Threatening Hawaii

Visualization showing accumulated precipitation from three hurricanes (Genevieve, Iselle, and Julio) around the Hawaiian Islands, with Hurricane Iselle making landfall.

NASA's Global Precipitation Measurement mission has produced its first global map of rainfall and snowfall. The GPM Core Observatory launched on Feb. 27, 2014 as a collaboration between NASA and the Japan Aerospace Exploration Agency and acts as the standard to unify precipitation measurements from a network of 12 satellites. The result is NASA's Integrated Multi-satellitE Retrievals for GPM data product, called IMERG, which...

GPM Observes Snow Storm over Kentucky, West Virginia, and North Carolina (February 17, 2015)

The Global Precipitation Measurement (GPM) Core Satellite captured a 3-D image of a winter storm on February 17, 2015, that left six to 12 inches of snow over much of Kentucky, southwestern West Virginia, and northwestern North Carolina. The shades of blue in the 3-D image indicate rates of snowfall with more intense snowfall shown in darker blue. Underneath where it melts into rain, the most intense rainfall is shown in red. You can see a lot of variation in precipitation types over the southeastern portion of the United States.

The GPM Core Observatory carries two instruments that show the...

GPM Sees Hurricane Matthew's Life Cycle

Hurricane Matthew dropped a lot of rain, caused flooding and deaths in the state of North Carolina. Flooding is still widespread in North Carolina. Some rivers in North Carolina such as the Tar and the Neuse Rivers were still rising on Oct. 12, 2016.

At NASA's Goddard Space Flight Center in Greenbelt, Maryland, a rainfall analysis was accomplished using data from NASA's Integrated Multi-satellite Retrievals for GPM (IMERG). The GPM, or Global Precipitation Measurement, mission is a joint mission between NASA and the Japan Aerospace Exploration Agency (JAXA).

This rainfall analysis was...

NASA Satellite Captures 3-D View of Hurricane Matthew

NASA’s Precipitation Measurement Missions' GPM core satellite captured Hurricane Matthew in 3-D as it made landfall on Haiti and as it traveled up to the Florida coast.

The Global Precipitation Measurement Mission or GPM flew directly over the storm several times between October 2 - October 6, 2016. The view on October 6 reveals massive amounts of rainfall being produced by the storm as it approaches Florida.

The GPM core satellite carries two instruments that show the location and intensity of rain and snow, which defines a crucial part of the storm structure – and how it will behave. The...

GPM Captures Hurricane Matthew Before Haiti Landfall

This animation starts with an overview of North America, Central America, and the Caribbean. As the camera slowly pushes in, Hurricane Matthew begins to form. By the morning of Oct. 2, 2016, Matthew is a category 4 hurricane immediately south of Haiti and the Dominican Republic. Time then slows down to see GPM's GPROF swath reveal ground precipitation from the hurricane. Now, with the camera closer in the view rotates to reveal a curtain of three-dimensional radar data from GPM's DPR instrument. DPR shows us the 3-D structure of the hurricane's precipitation rates. Areas in blue and purple are...

GPM Provides a Closer Look at the Louisiana Floods

Twice on Aug. 12, 2016, GPM flew over a massive rainstorm that flooded large portions of Louisiana. The flooding was some of the worst ever in the state, resulting in a state of emergency. Tens of thousands of people were evacuated from their homes in the wake of this unprecedented event.

Throughout the course of Aug. 12 (UTC) GPM captured the internal structure of the storm twice and GPM IMERG measured the rainfall accumulation on the ground.

NASA's GPM satellite is designed to measure rainfall using both passive microwave (GMI) and radar (DPR) instruments. DPR can observe 3-D structures of...
