Its operations are often supported by NASA and the Federal Aviation Administration (FAA).

Introduction

The NSF/NCAR Gulfstream V is a unique research platform that has been used for a variety of atmospheric science and earth science research projects, including studies of climate change, weather patterns, and air quality. The aircraft is based at the Research Aviation Facility in Broomfield, Colorado, and has been used for missions in collaboration with researchers from institutions such as the Massachusetts Institute of Technology (MIT), Stanford University, and the University of California, Berkeley. The NSF/NCAR Gulfstream V has also participated in large-scale field campaigns like the Tropical Composition, Cloud and Climate Coupling (TC4) experiment and the Studies of Emissions and Atmospheric Composition, Clouds and Climate Coupling by Regional Surveys (SEAC4RS) mission. Its research activities are often coordinated with other NSF-funded projects and international research initiatives.

Design_and_Development

The NSF/NCAR Gulfstream V was modified from a standard Gulfstream V business jet to meet the specific needs of atmospheric research. The aircraft features a range of custom-designed instruments and sensor systems, including radar, lidar, and spectrometers, which are used to collect data on atmospheric conditions, cloud properties, and aerosol distributions. The aircraft's design and development involved collaboration with Gulfstream Aerospace, NCAR, and other research institutions, including the University of Wisconsin–Madison and the Cooperative Institute for Research in Environmental Sciences (CIRES). The NSF/NCAR Gulfstream V has undergone several upgrades and modifications over the years, including the installation of new instrumentation and avionics systems, with support from Boeing, Lockheed Martin, and the FAA.

Operational_History

The NSF/NCAR Gulfstream V has been operational since 2005 and has been used for a wide range of research missions, including hurricane surveillance, wildfire monitoring, and atmospheric sampling. The aircraft has flown missions in collaboration with researchers from institutions such as the University of Oklahoma, Texas A&M University, and the National Institute of Standards and Technology (NIST). The NSF/NCAR Gulfstream V has also participated in international field campaigns like the Convective and Orographically-induced Precipitation Study (COPS) and the Dependence of Humidity on Sea-surface Temperature (DHSST) experiment, working with partners like the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA). Its operations are often supported by US Air Force and US Navy resources.
