Hurricane Science

The GHRC has participated in a number of NASA field campaigns related to the Hurricane Science Research Program including the Convection and Moisture Experiments (CAMEX) series and the recent NASA Genesis and Rapid Intensification Processes (GRIP) mission conducted in August and September 2010. We are incorporating data from the Hurricane and Severe Storm Sentinel (HS3), a five-year Earth Venture 1 mission specifically targeted to investigate the processes that underlie hurricane intensity change in the Atlantic Ocean basin.

Two unmanned Global Hawk aircraft carry instruments to monitor tropical storms and the surrounding environment to investigate the processes that underlie hurricane formation and intensity change in the Atlantic Ocean basin. Field measurements occurred for one month each during the hurricane seasons of 2012-2014.

NASA's DC-8 aircraft, the WB-57 aircraft, and the Global Hawk Unmanned Airborne System (UAS) were configured with a suite of in situ and remote sensing instruments to observe and characterize the lifecycle of hurricanes. The GRIP deployment was 15 August – 30 September 2010 with bases in Ft. Lauderdale, FL for the DC-8, at Houston, TX for the WB-57, and at NASA Dryden Flight Research Facility, CA for the Global Hawk.

Investigated atmospheric structure, properties and processes in the tropical Eastern Pacific, using aircraft observations to validate observations from NASA's satellite "A-Train". Costa Rica, July 2007.

Characterized the evolution and structure of African Easterly Waves (AEWs) and Mesoscale Convective Systems over continental western Africa, and their associated impacts on regional water and energy budgets.  Cape Verde Islands, August 2006.

12 NASA ER-2 science flights included missions to Hurricanes Dennis and Emily, Tropical Storm Gert, and an eastern Pacific mesoscale complex that may possibly have further developed into Tropical Storm Eugene. Costa Rica, July 1-27, 2005.

Used the remotely-piloted Altus II aircraft to gather electrical, magnetic and optical measurements of thunderstorms.  This marked the first time a UAV was used to conduct lightning research. Naval Air Station Key West in Florida, August 2002.

The fourth in the CAMEX series, flew instrumented DC-8 and ER-2 research airborne platforms over, through, and around selected hurricanes as they approached landfall in the Caribbean, Gulf of Mexico, and along the east coast of the United States. Jacksonville Naval Air Station, Florida, 16 August - 24 September, 2001.

The third in the CAMEX series, collected data for research in tropical cyclone development, tracking, intensification, and landfalling impacts using NASA-funded aircraft and surface remote sensing instrumentation. Patrick Air Force Base, Florida from 6 August - 23 September, 1998.

GPM-GV

The NASA Global Precipitation Measurement Mission (GPM) Ground Validation (GV) program, as a member of the broader NASA Precipitation Measurement Mission, is providing ground and airborne precipitation datasets supporting physical validation of satellite-based precipitation retrieval algorithms. The GHRC is working with the GPM-GV Science Manager to support these GPM GV physical process studies, which rely on targeted field observations lasting roughly six weeks for intensive observation periods.

Hydrologic validation in extreme coastal and topographic gradients. Washington's Olympic Peninsula, Nov 2015-Feb 2016.

Collaborative effort between the U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Climate Research Facility and NASA's GPM-GV program, to provide complete characterization of convective cloud systems, precipitation, and the environment. Ponca City, OK, April-May, 2011, partnered with DOE-ARM.

Addressed shortcomings in GPM snowfall retrieval algorithm by collecting microphysical properties, associated remote sensing observations, and coordinated model simulations of precipitating snowOntario, Canada, Jan-Feb. 2012, partnered with Environment Canada.

Collected microphysical properties, associated remote sensing observations, and coordinated model simulations of high latitude precipitation systems. Helsinki, Finland, fall-winter 2010, partnered with CloudSat.
