RISObservation 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, ...
Development and Applications of the ARM Raman Lidar
Publisher: American Meteorological Society
Continuous Water Vapor Profiles from Operational Ground—Based Active and Passive Remote Sensors
Publisher: American Meteorological Society
Abstract: The Atmospheric Radiation Measurement program's Southern Great Plains Cloud and Radiation Testbed site central facility near Lamont, Oklahoma, offers unique operational water vapor profiling capabilities, including active ...
Applications of Kalman Filtering to Derive Water Vapor Profiles from Raman Lidar and Microwave Radiometers
Publisher: American Meteorological Society
Abstract: A two-stage retrieval technique is presented for deriving water vapor profiles from data provided by a Raman lidar, a microwave radiometer, a radio acoustic sounding system, and surface in situ instruments. In the first ...
Aircraft Evaluation of Ground-Based Raman Lidar Water Vapor Turbulence Profiles in Convective Mixed Layers
Publisher: American Meteorological Society
Abstract: igh temporal and vertical resolution water vapor measurements by Raman and differential absorption lidar systems have been used to characterize the turbulent fluctuations in the water vapor mixing ratio field in convective ...
Automated Retrievals of Water Vapor and Aerosol Profiles from an Operational Raman Lidar
Publisher: American Meteorological Society
Abstract: Automated routines have been developed to derive water vapor mixing ratio, relative humidity, aerosol extinction and backscatter coefficient, and linear depolarization profiles, as well as total precipitable water vapor ...
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 ...
Lidar Observations of Banded Convection during BLX83
Publisher: American Meteorological Society
Abstract: Lidar observations of clear-air convection during the 1983 Boundary Layer Experiment (BLX83) reveal the presence of elongated, parallel regions of updrafts marked by enhanced aerosol backscattering. These linear (banded) ...
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 ...
The MERRA-2 Aerosol Reanalysis, 1980 Onward. Part II: Evaluation and Case Studies
Publisher: American Meteorological Society
Abstract: AbstractThe Modern-Era Retrospective Analysis for Research and Applications, version 2 (MERRA-2), is NASA?s latest reanalysis for the satellite era (1980 onward) using the Goddard Earth Observing System, version 5 (GEOS-5), ...
