Airborne lidar observations of water vapor transport [PDF]

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
Water vapor, a minor constituent of the earth's atmosphere, plays a major role in the radiation budget and the water cycle with important implications for weather and climate. Due to the heterogeneous distribution of its sources, evaporation, and sinks, condensation and precipitation, and due to the complexity of atmospheric motion and mixing, its ...
