Using Satellites to Predict Malaria Outbreaks

Using NASA Satellite Data to Predict Malaria Outbreaks
Friday, September 15, 2017
In the Peruvian Amazon, the Anopheles darlingi mosquito is most responsible for spreading malaria. With funding from NASA's Applied Sciences Program, scientists are turning to the agency’s fleet of Earth-observing satellites to develop a system that uses satellite and other data to help forecast malaria outbreaks at the household level months in advance and prevent them from happening. Credits: NASA's Goddard Space Flight Center / Joy Ng In the Amazon Rainforest, few animals are as dangerous to humans as mosquitos that transmit malaria. The tropical disease can bring on high fever, headaches...

GPM Examines Typhoon Talim's Large Eye

GPM Examines Typhoon Talim's Large Eye
The GPM cored observatory had another outstanding view of typhoon Talim in the western Pacific Ocean on September 13, 2017 at 1537 utc. A large eye was Talim's most distinctive feature. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) showed the location of intense rainfall within Talim's distinct eye wall. DPR revealed that rain was falling at a rate of over 232 mm (9.13 inches) per hour in convective storms in the western side of the typhoon's eye wall. GPM also showed that rainfall was far weaker to the the east of Talim's center. This dramatic 3-D view of Talim's

GPM Finds Sheared Hurricane Jose Has Very Tall Storms

GPM Finds Sheared Hurricane Jose Has Very Tall Storms
On Wednesday September 13, 2017 at 10:35 AM AST (1435 UTC) the GPM core observatory satellite traveled above persistent hurricane Jose as it was meandering in the Atlantic Ocean. GPM found that even though Jose was affected by strong northwesterly shear it contained very powerful convective storms. GPM's Dual-Frequency Precipitation Radar (DPR) found extremely intense downpours within these storms where rain was measured by DPR falling at a rate of over 8.9 inches (227 mm) per hour. GPM's radar (DPR Ku Band) was used to show a 3-D cross-section of the precipitation within hurricane Jose. This

GPM Examines Hurricane Irma

GPM Examines Hurricane Irma
Wednesday, September 13, 2017
The GPM core observatory satellite had an exceptional view of hurricane Irma's eye when it flew above it on September 5, 2017 at 12:52 PM AST (1652 UTC). This visualization shows a rainfall analysis that was derived from GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) data. Irma was approaching the Leeward Islands with maximum sustained winds of about 178 mph (155 kts). This made Irma a dangerous category five hurricane on the Saffir-Simpson hurricane wind scale. Intense rainfall is shown within Irma's nearly circular eye. This 3-D cross-section through Irma's eye was...

GPM Sees Typhoon Talim Threatening Islands Of Japan

GPM Sees Typhoon Talim Threatening Islands Of Japan
The Joint Typhoon Warning Center (JTWC) predicts that typhoon Kalim in the western Pacific Ocean will intensify and threaten the islands of southern Japan in the the new three days. Environmental conditions such as low vertical wind shear and warm sea surface temperatures are favorable for Talim's intensification. Talim's winds are expected to increase to a peak of 115 kts as it re-curves toward the the Japanese island of Kyushu. The GPM core observatory satellite scanned the western side of typhoon Talim on September 13, 2017 at 0216 UTC. GPM's Microwave Imager (GMI) instrument collected data

Irma’s Heavy Rainfall Measured With GPM IMERG

Irma’s Heavy Rainfall Measured With NASA’s IMERG
Hurricane Irma dropped extremely heavy rain at times during it’s trek from near the Cape Verdi Islands through the northern Leeward islands, Cuba and the southeastern United States. Over 16 inches (406 mm) of rain was reported in Guantanamo, in the easternmost province of Cuba, as the category five hurricane battered the country. Almost 16 inches (406 mm) of rain was also reported at Fort Pierce on the eastern side of Florida. Charleston, South Carolina reported 6 inches (152.4 mm) of rain in 24 hour. This heavy rainfall plus storm surge flooding caused the worst flooding in Charleston since

Intensifying Tropical Storm Jose

Intensifying Tropical Storm Jose
On September 5, 2017 tropical Storm Jose became the tenth named storm of the Atlantic hurricane season. The GPM core observatory satellite passed above the intensifying tropical cyclone on September 6, 2017 at 00:45 AM AST (0435 UTC). Data collected by GPM's Microwave Imager (GMI) at that time showed that weak bands of rain were starting to develop around Jose's center of circulation. GPM's Dual-Frequency Precipitation Radar (DPR) data swath revealed the location of heavy rain in a feeder band on Jose's western side. DPR found that rain in this area was falling at a rate of over 5.3 inches

GPM Satellite Probes Dangerous Category Five Hurricane Irma

GPM Satellite Probes Dangerous Category Five Hurricane Irma
The GPM core observatory satellite had an exceptional view of hurricane Irma's eye when it flew above on September 5, 2017 at 12:52 PM AST (1652 UTC). This image shows a rainfall analysis that was derived from GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) data. Irma was approaching the Leeward Islands with maximum sustained winds of about 178 mph (155 kts). This made Irma a dangerous category five hurricane on the Saffir-Simpson hurricane wind scale. Intense rainfall is shown within Irma's nearly circular eye. GPM's DPR (shown in lighter shades) uncloaked

Hurricane Irma's Heat Engine Exposed

Hurricane Irma's Heat Engine Exposed
Wednesday, September 6, 2017
At 1 PM EDT (1700 UTC) on September 5, 2017, the radar on the Global Precipitation Measuring Mission (GPM) satellite captured this 3D view of the heat engine inside of category-5 Hurricane Irma. Under the central ring of clouds that circles the eye, water that had evaporated from the ocean surface condenses, releases heat, and powers the circling winds of the hurricane. The radar on the GPM satellite is able to estimate how much water is falling as precipitation inside of the hurricane, which serves as a guide to how much energy is being released inside the hurricane's central "heat engine."...

GPM Sees Potential Tropical Depression Developing In The Gulf Of Mexico

GPM Sees Potential Tropical Depression Developing In The Gulf Of Mexico
The GPM Core Observatory satellite had an excellent view of a potential tropical depression developing in the Gulf Of Mexico on September 5, 2017 at 3:34 AM CDT (0834 UTC). GPM found that powerful convective storms were dropping heavy rainfall in the Gulf of Mexico east Mexico's coast. GPM's Dual-Frequency Precipitation Radar (DPR) instrument measured rain falling at a rate of over 9.2 inches (233 mm) per hour in an intense band of storms. GPM's Radar (DPR Ku Band) data was used to examine the 3-D structure of precipitation in this area of strong convective storms. GPM's DPR showed that storm
