5 Year Anniversary of Hurricane Arthur

5 Year Anniversary of Hurricane Arthur
Friday, June 21, 2019
TRMM overpass of Hurricane Arthur from July 3, 2014. View fullscreen in STORM Event Viewer June marks the official start of the Atlantic hurricane season. And although strong tropical cyclones are rare in June in the Atlantic, it will soon be the 5-year anniversary of Hurricane Arthur, which became a tropical depression in very late June 2014 before hitting the Outer Banks of North Carolina as a Category 2 hurricane in early July. As with most storms early in the season, Arthur formed not from a tropical wave moving off the coast of Africa but from an old frontal boundary that stalls off the...

2019 Hurricane Season Resources

2019 Hurricane Season Banner
Monday, June 3, 2019
NASA has a unique and important view of hurricanes around the planet. Satellites and aircraft watch as storms form, travel across the ocean and sometimes, make landfall. After the hurricanes have passed, the satellites and aircraft see the aftermath of hurricanes, from downed forests to mass power loss.

Using GPM Data to Understand Hurricanes

Using GPM Data to Understand Hurricanes
Thursday, May 30, 2019
The 2019 Atlantic "hurricane season" is officially upon us and runs through November 30th. Did you know that GPM data play a fundamental role in the ability to monitor existing storm activity such as capturing the location and intensity of rainfall inside a storm, as well as improving weather and precipitation forecasts through assimilation of instantaneous precipitation information? Here are a few applications of GPM data used to study hurricanes and how the data was then used for decision-making. Monitoring Irma with GPM This image shows rainfall analysis that was derived from GPM's GMI data...

GPM Flies Over Developing Tropical Storm Idai Twice

GPM Flies Over Developing Tropical Storm Idai Twice
Intense Tropical Cyclone Idai started as a tropical depression on the 4th of March, 2019, off the coast of Mozambique. After making landfall over Mozambique it turned back over the Mozambique Channel and strengthened to become a tropical cyclone on the 10th of March. The GPM satellite captured the cyclone with both the GPM Microwave Imager (GMI) and the Dual-frequency Precipitation Radar (DPR) on the 11th of March at 04:36 UTC when the storm was in the middle on the Mozambique Channel. The DPR captured a well-developed eye, seen at the center of the image. It flew over the storm once again at

Using GPM Data for Weather, Climate, and Land Surface Modeling

GPM Applications: Weather
Friday, February 8, 2019
Using GPM Data for Weather, Climate, and Land Surface Modeling Variations in rain, snow, and other forms of precipitation are an integral part in everyday weather and long term climate trends. Initialization of short-term weather and long-term climate models with accurate precipitation information enhances their prediction skills and extends their skillful lead times. To get the resolution and temporal coverage to measure precipitation across the globe, we often rely on satellite information. Satellite data can play a fundamental role in our ability to monitor and predict weather systems as

Using GPM Data for Water Resources, Agricultural Forecasting & Food Security

GPM Applications: Water & Agriculture
Thursday, February 7, 2019
Growing human population, increased demand for water and energy, and a changing climate have contributed to concerns of how freshwater resources and food supply and production may be stressed. Both water resource managers and the agricultural community need to know the amount, distribution, timing and onset of seasonal rain and snow to prepare for freshwater shortages and forecast crop yields. Remotely sensed precipitation estimates play a key role in predicting changes in freshwater supply and agricultural forecasting. Specifically, GPM provides advance precipitation measurements on regional

Using GPM Data for Energy Infrastructure and Management

GPM Applications: Energy
Thursday, February 7, 2019
In many areas, energy infrastructure assets, such as power plants and electric grids, can suffer damage or disruption in service due to a variety of climate-related impacts like extreme precipitation, high temperatures, drought, and rising sea levels. For example, warmer temperatures and little rainfall can cause changes in peak streamflow conditions that affect hydropower generation. Heavy precipitation events and flooding can impact a region’s energy infrastructure, including electric grid equipment, which has cascading effects on freshwater supplies and emergency services. The Energy

Using GPM Data for Ecological Management

GPM Applications: Ecology
Wednesday, February 6, 2019
The impacts of climate change are already having a profound effect on ecosystems. Changes in temperature and precipitation patterns affect species and communities in diverse ways, such as declines in species and species diversity, changing interactions between species, and modification of ecosystems. Effective ecosystem management is critical to maintaining and repairing the natural environments in order to reliably support human needs while conserving and sustaining ecological services and diversity. Satellite observations can provide critical information relevant to the distribution of

GPM IMERG Measures Hurricane Michaels Rainfall Accumulation

GPM IMERG Measures Hurricane Michaels Rainfall Accumulation
At least eleven deaths have now been attributed to deadly hurricane Micheal. Some casualties resulted not only from Micheal's destructive winds and storm surges but also from the blinding rain that Micheal produced as it battered states from Florida northeastward through Virginia. Today tropical storm Micheal is moving out over the Atlantic Ocean and has transitioned into a powerful extratropical storm. This animation using the GPM IMERG multi-satellite dataset shows the estimated total rainfall accumulation for #HurricaneMichael from 10/8/18 - 10/12/18. Learn more: https://t.co/aJuEp6o855 pic

IMERG Measures Flooding Rainfall In Deadly California Wildfire Areas

IMERG Measures Flooding Rainfall In Deadly California Wildfire Areas
Heavy precipitation has been falling in areas of California that were recently devastated by deadly wildfires. This flooding rainfall has resulted in evacuations in burn scarred areas such as Butte County where the deadly Camp Fire hit this month. Flash floods, debris flows and mudslides are now predicted in areas where deadly wildfires stripped away vegetation. On a positive note these Pacific storms are expected to dampen wildfires and replenish the Sierra Nevada snowpack. This snowpack is an important source of water for California's streams and rivers. NASA's Integrated Multi-satellitE
