Field Evaluation of Column CO2 Retrievals from Intensity-Modulated Continuous-Wave Differential Absorption Lidar Measurements during ACT-America
Joel F. Campbell, Bing Lin, Michael D. Obland +13
We present an evaluation of airborne Intensity-Modulated Continuous-Wave (IM-CW) lidar measurements of atmospheric column CO2 mole fractions during the ACT-America project. This li…
Advanced sine wave modulation of continuous wave laser system for atmospheric CO2 differential absorption measurements
Joel F. Campbell, Bing Lin, Amin R. Nehrir
In this theoretical study, modulation techniques are developed to support the Active Sensing of CO2 Emissions over Nights, Days, and Seasons (ASCENDS) mission. A CW lidar system us…
Non-linear swept frequency technique for CO2 measurements using a CW laser system
Joel F. Campbell
A system using a non-linear multi-swept sine wave system is described which employs a multi-channel, multi-swept orthogonal waves, to separate channels and make multiple, simultane…
A Low Cost Remote Sensing System Using PC and Stereo Equipment
Joel F. Campbell, Michael A. Flood, Narasimha S. Prasad +1
A system using a personal computer, speaker, and a microphone is used to detect objects, and make crude measurements using a carrier modulated by a pseudorandom noise (PN) code. Th…
