Long Island Sound Tropospheric Ozone Study

GEOstationary Coastal and Air Pollution Events (GEO-CAPE) Airborne Simulator (GCAS) is an airborne push-broom instrument consisting of two spectrometers. It was developed by the Radiometric Calibration and Flight Development Laboratory at Goddard Space Flight Center (GSFC) as a simulator for the GEO-CAPE mission. The first spectrometer in GCAS operates in the ultraviolet to visible (300-490 nm) range for air quality observations of nitrogen dioxide (NO2), ozone (O3), formaldehyde (HCHO), and other trace gases. The second spectrometer operates in the visible to near-infrared (480-900 nm) to provide measurements of ocean color. GCAS has a typical spatial resolution of 250m across track and 500m along track at an altitude of 9 km and has a frame rate of 12 Hz.

The High Altitude Lidar Observatory (HALO) is an active remote, airborne lidar developed by NASA Langley Research Center. HALO operates across 4 wavelengths (1645, 1064, 935, 532 nm) and uses a combination of Differential Absorption Lidar (DIAL) and High Spectral Resolution Lidar (HSRL) methods to measure lidar backscatter and depolarization ratio. It provides vertical profiles of aerosol and cloud optical properties, atmospheric water vapor, and methane at a data rate of 2 Hz. HALO has a nominal spatial resolution of 12 km horizontally and 315 m vertically at an altitude of 10 km.

The Geostationary Trace gas and Aerosol Sensor Optimization (GeoTASO) is an airborne pushbroom spectrometer developed by Ball Aerospace through support by NASA’s Earth Science Technology Office. GeoTASO measures nadir backscattered solar radiation in the ultraviolet (290-400 nm) and visible (415-695 nm) wavelengths. These measurements can be used to determine aerosols and trace gases in the atmosphere such as ozone, formaldehyde, and nitrogen dioxide. GeoTASO has a spatial resolution of about 250 m x 250 m and has an integration time of 0.25 s.
