CARBO (Carbon Balance Observatory) is a wide field of view, compact, modular and high-performance remote sensing instrument designed to measure molecular abundances of CO2, CO, CH4, as well as the Solar Induced Fluorescence (SIF) from the low Earth orbit (LEO). CARBO's key technology is immersion grating which delivers spectral resolving powers ranging from 10,000 to 20,000 for detection precisions of XCO2 <1.5 ppm, XCH4 <7 ppb, XCO <5 ppb. CARBO's immersion gating technology allows for a small and light package as a cost effective solution for space-based carbon climate remote sensing. This concept opens up of the option of a constellation of small satellites carrying multiple CARBO instruments, which can significantly enhance our understanding of global carbon cycle.
