XCH4 Spectrometer L3 Segments and Mosaics
Listed in National Center for Atmospheric Research
MethaneAIR is a set of two passive near-IR imaging spectrometers that report methane (CH4) column mean dry mole fraction that flew aboard the NSF G-V. The instrument was mounted on the floor, between L2 and R2, and used the fore nadir viewport.
Description
Shutters mounted on each spectrometer were used to perform on-demand dark calibrations throughout the flight.
