It is capable of measurements to altitudes approaching 30,000 feet over ranges of 1500 nautical miles, and can be operated at speeds that enable both relatively slow sampling and rapid deployment to field sites throughout the world. The aircraft is configured for versatile research applications. It accommodates a variety of external probes for aerosol and turbulence measurements and internal sampling devices for measuring atmospheric composition and state variables. The G-1 has sufficient cabin volume, electrical power and payload capabilities, and flight characteristics to accommodate a large variety of instrument systems and experimental equipment configurations.
Internal instrumentation is mounted in removable racks that enables rapid reconfiguration.
Data acquisition is performed by an onboard computer system that can accommodate a wide range of analog and digital inputs. Output can be provided on PC-compatible disks or magnetic tape in a format acceptable to the user. Additional information on the performance characteristics, instrument systems, and data acquisition for the G-1 can be found on the Internet. Priority for G-1 use is given to users from the DOE Atmospheric Chemistry Program. Proposals stating research objectives and requesting aircraft time must be submitted to the DOE for review by a DOE-empowered Research Aviation Facility Advisory Panel as far in advance as practical.
