RISObservation of Lower-Atmospheric Moisture Structure and its Evolution Using a Raman Lidar
Publisher: American Meteorological Society
Abstract: Observations of the water-vapor mixing ratio in the lower atmosphere and its temporal evolution have been made with a Raman lidar. Comparison with an independent radiosonde measurement indicated excellent agreement. The ...
Estimating the Orientation and Spacing of Midlatitude Linear Convective Boundary Layer Features: Cloud Streets
Publisher: American Meteorological Society
Abstract: inear features in a clear convective boundary layer (CBL) over the North Atlantic Ocean were studied during a weak cold air outbreak using a down-looking airborne lidar. Sequential lidar profiles were placed together and ...
Observation of Atmospheric Fronts Using Raman Lidar Moisture Measurements
Publisher: American Meteorological Society
Abstract: This paper presents the results of a field program using a ground-based Raman lidar system to observe changes in moisture profiles as a cold and a warm front passed over the NASA/Goddard Space Flight Center in Greenbelt, ...
Cold-Air Outbreak during GALE: Lidar Observations and Modeling of Boundary Layer Dynamics
Publisher: American Meteorological Society
Abstract: Two cold-air outbreaks were studied during the Genesis of Atlantic Lows Experiment. A lidar system was operated to observe the boundary layer evolution and the development of clouds. On the first day (30 January 1986) ...
Inference of Marine Atmospheric Boundary Layer Moisture and Temperature Structure Using Airborne Lidar and Infrared Radiometer Data
Publisher: American Meteorological Society
Abstract: A new technique for retrieving near-surface moisture and profiles of mixing ratio and potential temperature through the depth of the marine atmospheric boundary layer (MABL) using airborne lidar and multichannel infrared ...
Lidar Observations of Vertically Organized Convection in the Planetary Boundary Layer over the Ocean
Publisher: American Meteorological Society
Abstract: Observations of a convective planetary boundary layer (PBL) were made with an airborne, downward-looking lidar system over the Atlantic Ocean during a cold air outbreak. The lidar data revealed well-organized, regularly ...
Structure of an Internal Bore and Dissipating Gravity Current as Revealed by Raman Lidar
Publisher: American Meteorological Society
Abstract: Detailed moisture observations from a ground-based Raman lidar and special radiosonde data of two disturbances associated with a dissipating gust front are presented. A synthesis of the lidar data with conventional ...
Raman Lidar Profiling of Atmospheric Water Vapor: Simultaneous Measurements with Two Collocated Systems
Publisher: American Meteorological Society
Abstract: Raman lidar is a loading candidate for providing the detailed space-and time-resolved measurements of water vapor needed by a variety of atmospheric studies. Simultaneous measurements of atmospheric watervapor are described ...
A Comparison of Water Vapor Measurements Made by Raman Lidar and Radiosondes
Publisher: American Meteorological Society
Abstract: This paper examines the calibration characteristics of the NASA/GSFC Raman water vapor lidar during three field experiments that occurred between 1991 and 1993. The lidar water vapor profiles are calibrated using relative ...
Scientific Investigations Planned for the Lidar In-Space Technology Experiment (LITE)
Publisher: American Meteorological Society
Abstract: The Lidar In-Space Technology Experiment (LITE) is being developed by NASA/Langley Research Center for a series of flights on the space shuttle beginning in 1994. Employing a three-wave-length Nd:YAG laser and a 1-m-diameter ...
