Short summary
This study, part of my 2024 postdoctoral research, explores an all-fiber coupled laser heterodyne radiometer (LHR) for CO2 measurements using a tunable diode laser. The LHR employs balanced detection to measure tropospheric CO2 column concentrations. Simulations are validated against previously validated instruments. This work enhances greenhouse gas monitoring and supports campaigns for emissions studies and satellite validation.
