Anomalies in TMPA-RT Dec. 18 - 19, 2016

Anomalies in the DMSP F-16 input data for the TMPA-RT created streaks of precipitation over open-ocean regions. We have now deleted faulty data and rerun the TMPA-RT for the period: 18 December 2016 at 09 UTC to 19 December 2016 at 18 UTC. Please re-pull the affected data files. There appears to be no corresponding issue with the IMERG data files due to different quality control routines.

TRMM Wins the 2016 Group Pecora Award

TRMM wins the 2016 Group Pecora Award
Friday, August 26, 2016
The William T. Pecora Award is presented annually to individuals or groups that make outstanding contributions toward understanding the Earth by means of remote sensing. The award is sponsored jointly by the Department of the Interior (DOI) and the National Aeronautics and Space Administration (NASA). The award was established in 1974 to honor the memory of Dr. William T. Pecora, former Director of the U.S. Geological Survey and Under Secretary, Department of the Interior. Dr. Pecora was a motivating force behind the establishment of a program for civil remote sensing of the Earth from space...

TRMM Spacecraft Re-enters Over Tropics

The Tropical Rainfall Measuring Mission (TRMM) spacecraft re-entered the Earth’s atmosphere on June 15, 2015, at 11:55 p.m. EDT, over the South Indian Ocean, according to the U.S. Strategic Command’s Joint Functional Component Command for Space through the Joint Space Operations Center (JSpOC). The U.S. Space Surveillance Network, operated by the Defense Department's JSpOC, had been closely monitoring TRMM’s descent since the mission was ended in April. Most of the spacecraft was expected to burn up in the atmosphere during its uncontrolled re-entry. This U.S. Air Force map shows the

GPM Views Typhoon Dolphin Headed For Guam

GPM Views Typhoon Dolphin Headed For Guam
Typhoon Dolphin formed south of Pohnpei in the western Pacific Ocean on May 7, 2015. Dolphin's power has oscillated from a weak tropical depression to typhoon intensity over the past five days. Dolphin is now an intensifying typhoon headed westward. The GPM core observatory satellite flew over Dolphin on May 12, 2015 at 2301 UTC. At that time Dolphin's wind speeds were estimated at about 65 kts (75 mph). Rainfall collected by GPM's Microwave Imager (GMI) showed that rain was falling at a rate of over 47 mm (1.9 inches) per hour in a feeder band to the southeast of Dolphin's eye. Ku Band data

Ana Becomes First 2015 Atlantic Tropical Storm & Weakens Ashore

Ana Becomes First 2015 Atlantic Tropical Storm & Weakens Ashore
On May 9, 2015 at 1626 UTC ( 12:26 PM EDT) the GPM satellite flew over when Ana was making the change from subtropical storm to tropical storm. Convective storms near the inner-core region were warming the center of the storm with heat generated by condensation. GPM's Microwave Imager (GMI) measured rain falling at at rate of over 58.7 (2.31 inches) per hour in these convective storms near ANA's center. The lighter swath to the west of Ana's center shows the area viewed by GPM's Ku/Ka-band Dual-frequency Precipitation Radar (DPR). On Sunday morning (May 10, 2015) Tropical storm ANA dropped

GPM Flys Above Subtropical Storm Ana

GPM Flys Above Subtropical Storm ANA
During the past few days subtropical storm Ana was developing off the southeastern coast of the United States. Yesterday and today the GPM core observatory satellite had two good views of subtropical storm Ana. The image above shows the developing subtropical storm on May 7, 2015 at 1636 UTC (12:36 PM EDT). This GPM pass occurred a little over 10 hours before the National Hurricane Center (NHC) issued their first advisory at 0300 UTC ( 11:00 PM EDT). This image shows rainfall derived from GPM's Ku/Ka-band Dual-frequency Precipitation Radar (DPR) and a multi-channel GPM Microwave Imager (GMI)
