Abstract

We propose an imaging grating spectrometer suite with an agile pointing system and two-dimensional detectors to monitor global and regional greenhouse gas fluxes and target local emission. Three imaging spectrometers cover the nitrogen dioxide (NO2) band between 460 and 480 nm, the oxygen (O2) A band and solar-induced chlorophyll fluorescence (SIF) between 747 and 783 nm, and the weak carbon dioxide (CO2) and methane (CH4) absorption band at 1.6 μm with a spectral resolution of 0.1, 0.1, and 0.2 nm, respectively. We observe solar reflected spectra to retrieve column-averaged dry air mole fractions and cover entire emission areas such as mega cities, coal mines, and landfills with spatial resolution of 1 km.
