The Atmospheric Carbon and Transport - America (ACT-America) was a multi-year NASA field investigation that focused on studying atmospheric carbon dioxide and methane transport across the Midwest, Mid-Atlantic, and southern United States. ACT-America consisted of five deployments from 2016 to 2019 across the eastern United States. NASA's C-130 and B-200 aircraft were used to collect measurements of greenhouse gases and aerosols in the atmosphere. ACT-America was one of Earth Venture Suborbital 2 (EVS-2) projects.
The Cloud Physics Lidar (CPL) is an airborne lidar system designed specifically to provide multi-wavelength measurements of cirrus clouds, sub-visual cirrus clouds, and aerosols. It measures lidar backscatter across three wavelengths: 355 nm, 532 nm, and 1064 nm. These measurements can be used to derive cloud optical depth, particle size distribution, extinction profiles, aerosol layers, and other properties. CPL has a vertical resolution of 30 m and a typical horizontal resolution of 200 m.
The Programmable Flask Package (PFP) is a type of whole air sampler. This instrument consists of twelve glass flasks that can be filled with air. The samples collected by the PFP are sent to NOAA’s Global Monitoring Division and INSTAR’s Staple Isotope Lab where they are tested for trace gases. This instrument is used to monitor multiple types of trace gases.

The Picarro gas concentration analyzer is an in situ airborne or ground-based sensor manufactured by Picarro, Inc. It uses Wavelength-Scanned-Cavity Ring Spectroscopy (WS-CRDS) to measure trace gases such as carbon dioxide, carbon monoxide, methane, and water vapor. For carbon dioxide measurements, the laser within Picarro operates at 1603 nm wavelength and 1651 nm wavelength for methane and water vapor measurements. Picarro has a typical sampling time of 2.5 seconds. Depending on the model, Picarro can also provide measurements of carbon isotopes for gas concentrations.

The Continuous O3 Monitor uses ultraviolet beams to monitor the ozone in the air that is pulled into the instrument. The Continuous O3 Monitor has a high temporal resolution, and can take highly accurate measurements. The Continuous O3 Monitor is mounted to an aircraft. The instrument is manufactured by 2B Technologies.
The Multi-functional Fiber Laser Lidar (MFLL) is an airborne lidar system that measures atmospheric carbon dioxide (CO2). It consists of a multi-frequency, single-beam Laser Absorption Spectrometer (LAS) and a Pseudo-random Noise (PN) altimeter. The LAS instrument operates at 1571 nm to measure the column amount of CO2. The PN altimeter operates at the 1596 nm wavelength and measures the path length from the aircraft to the scattering surface and/or cloud top. MFLL has a typical temporal resolution of 10 Hz and a spatial resolution of 1 m at an altitude of 500 m.
The Fourier Transformation Spectrometer (FTS) is a high-resolution airborne and ground-based spectrometer. FTS measures the solar radiance reflected from the surface, which can be used to derive measurements of carbon monoxide (CO), carbon dioxide (CO2), and methane (CH4) in the atmosphere. It has a spatial resolution of around 100m x 1000m and a measurement frequency of 1 Hz for typical research flight conditions.

The Compact Atmospheric Multispecies Spectrometer (CAMS) is an in situ airborne spectrometer developed by the University of Colorado. CAMS uses mid-IR (3.53 μm) absorption spectroscopy to measure formaldehyde and ethane in the atmosphere. It utilizes difference-frequency generation (DFG) to produce the mid-IR light by mixing two near-IR (1562 and 1083 nm) laser sources. CAMS provides high-precision measurements at a sampling frequency of 1 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.
