    Simultaneous remote sensing of multiple atmospheric gases (CO2, CH4, and H2O) based on an all-fiber laser heterodyne spectroradiometer

    We report an all-fiber, near-infrared laser heterodyne radiometer (LHR) that uses two distributed feedback (DFB) diode lasers as local oscillators. This scheme allows the retrieval of the column abundances of ...
