Abstract

CO2 monitoring over an atmospheric column provides crucial information for climate change monitoring. A possible implementation for this measurement is IPDA (Integrated-Path-Differential-Absorption) lidar on a satellite that measures the absorption difference between two close wavelengths (λON, absorbed by CO2 and λOFF, not absorbed). Distance to ground must be simultaneously measured. Pulses must be short enough for telemetry (<100ns), narrow-linewidth for spectrally resolved absorption measurement (<100MHz) and high-energy for signal-to-noise ratio (mJ-level).
