Advancement of the O2 Subsystem to Demonstrate Retrieval of XCO2 Using Simultaneous Laser Absorption Spectrometer Integrated Column Measurements of CO2 and O2
Achieve scalability of a 1.26 µm fiber Raman amplifier (FRA) to 5W with an optical-to-optical efficiency of >50%, that is compatible with ITT's modulated CW Laser Absorption Spectrometer (LAS) in support of the ASCENDS mission. Advance the retrieval/software tools to demonstrate the retrieval of dry air mixing ratio of CO2 using simultaneous active O2 and CO2 integrated column measurements.
