Hurricane and Severe Storm Sentinel (HS3)

HS3 Banner

Hurricane and Severe Storm Sentinel (HS3) is a NASA airborne field campaign aimed at better understanding the physical processes that control hurricane intensity change. HS3 will help answer questions related to the roles of environmental conditions and internal storm structures to storm intensification. Due to the nature of the questions that HS3 mission is addressing, it involves a variety of in-situ, satellite observations, airborne data, meteorological analyses, and simulation data. HS3 is a 5-year mission with three observation years (2012, 2013, 2014).

Image of the flight tracks that the NASA (AV-6) Global Hawk (GH) unmanned aircraft has flown for the NASA Hurricane and Severe Storm Sentinel (HS3) campaign (2012,2013,2014) to date. It shows incredible coverage that could not have been done with conventional aircraft.

Instrument data will be available at GHRC in early 2015.

A specialized data system is currently in the works.The Global Hydrology Resource Center (GHRC) is considering all these needs in designing a data system for HS3 based on experience with past airborne field campaigns. To address the science questions, the data system will include a visual data exploration tool that is fully integrated into the data catalog. The tool will allow visually augmenting airborne data with analyses and simulations. All HS3 tools will be supported by an enterprise service architecture that will allow scaling, easy integration of new tools and existing services, and integration of new ESDIS metadata and security guidelines.
