FTS
Fourier Transform Spectrometer

The Fourier Transform Spectrometer (FTS) is a high-resolution spectrometer used in both airborne and ground-based applications. FTS measures the solar radiance reflected from surfaces, which can be used to estimate atmospheric concentrations of carbon monoxide (CO), carbon dioxide (CO2), and methane (CH4). It provides a spatial resolution of approximately 100m by 1000m and operates at a measurement frequency of 1 Hz during typical research flights.
