| 内容記述 | Atmospheric carbon dioxide (CO2) is an important greenhouse gas that significantly contributes to the carbon cycle and
global radiation budget on Earth. Active remote sensing of CO2 is important to address several limitations that contend
with passive sensors. A 2-micron double-pulsed, Integrated Path Differential Absorption (IPDA) lidar instrument for
ground and airborne atmospheric CO2 concentration measurements via direct detection method is being developed at
NASA Langley Research Center. This active remote sensing instrument will provide an alternate approach of measuring
atmospheric CO2 concentrations with significant advantages. A high energy pulsed approach provides high-precision
measurement capability by having high signal-to-noise ratio level and unambiguously eliminates the contamination from
aerosols and clouds that can bias the IPDA measurement. Commercial, on the shelf, components are implemented for the
detection system. Instrument integration will be presented in this paper as well as a background for CO2 measurement at
