Top 5 GPM Research Highlights

Top 5 GPM Research Highlights

GPM celebrates its fifth anniversary since launching from Tanegashima Island, Japan on February 27, 2014. This milestone not only marks the launch but also the many scientific research accomplishments that GPM has made in advancing our understanding of precipitation, from light rain to intense thunderstorms, to further our understanding of the water cycle. 

Here are five of GPM’s most significant research accomplishments and their contributions to weather and climate science in its first five years in space:

 

PPS Announcing Data Product Version Change for GPM Level 2 and Level 3 GPROF Data -Available Starting Mon Feb. 04, 2019

Beginning on Monday February 04, 2019, the Level 2 and Level 3 GPM GPROF products will be produced with an updated monthly emissivity class file (see developers comments below).  PPS will increment the product version for all Level 2 and Level 3 GPROF products starting with the first full orbit on data date February 1, 2019.  The current version of these products will cease with data date Jan 31, 2019 and will remain unchanged. 
The new production version numbers/ designations will be incremented as shown in the table below.

Change in letter on GMI NRT GPROF data products

Effective on the date and time above, all the NRY GPROF data product verson  numbers were changed by increasing the letter of the data product version. This letter change means that data products were changed but no backward processing is undertaken. Only the products forward of the date/time have been altered.  So, for GMI GPROF the vesion changed from V05A to V05B. Other instrument GPROF retrievals had a similar change but appropriate to their starting data product version.

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 IMERG Used To Analyze Tropical Storm Usagi's Rainfall

Usagi strengthened to hurricane intensity as it approached Vietnam from the South China Sea but weakened to tropical storm intensity when coming ashore. Very heavy rainfall and damaging winds accompanied tropical storm Usagi when it hit Vietnam's southern coast. More than 350 mm (14 inches) of rainfall was reported causing widespread flooding around Ho Chi Minh City.

Tropical Cyclone Gaja's Rainfall Measured With IMERG

Tropical Cyclone Gaja's Rainfall Measured With IMERG

Tropical cyclone Gaja recently caused the deaths of at least 33 people in the southern India state of Tamil Nadu. Gaja's high wind and heavy rains caused landslides and building collapses. Gaja's maximum sustained winds had reached about 75kts (86 mph) when it hit southern India on Friday November 16, 2018. This meant that Gaja was the equivalent of a category one on the Saffir-Simpson hurricane wind scale. Today another tropical low is also moving over southern India and is expected to produce more heavy rainfall in the same area.

Italy's Extreme Rainfall Examined With IMERG

Italy's Extreme Rainfall Examined With IMERG

During the past week a strong low-pressure system moving through southern Europe battered, drenched and flooded Italy. It caused flooding, landslides and other damage to large areas of the country. The deaths of at least 11 people have been attributed to this stormy weather. High winds knocked down many trees and heavy rainfall from these storms contributed to flooding in large areas of Italy. Venice was inundated when heavy rain fell and a surge of water from the Adriatic Sea was pushed into the city by the storm's very high winds.
