The 27–28 October 1986 FIRE IFO Cirrus Case Study: Cloud Optical Properties Determined by High Spectral Resolution Lidar
Publisher: American Meteorological Society
Abstract: During the FIRE cirrus IFO, the High Spectral Resolution Lidar (HSRL) was operated from a roof top site on the University of Wisconsin?Madison campus. Because the HSRL technique separately measures the molecular and cloud ...
Lidar Observations of Mixed Layer Dynamics: Tests of Parameterized Entrainment Models of Mixed Layer Growth Rate
Publisher: American Meteorological Society
Abstract: Ground based lidar measurements of the atmospheric mixed layer depth, the entrainment zone depth and the wind speed and wind direction were used to test various parameterized entrainment models of mixed layer growth rate. ...
Remote Determination of Winds, Turbulence Spectra and Energy Dissipation Rates in the Boundary Layer from Lidar Measurements
Publisher: American Meteorological Society
Abstract: Procedures are described for the analysis of lidar data to remotely measure 1) spectra of aerosol density fluctuations, 2) radial and transverse components of the mean wind and turbulent fluctuations of the transverse ...
Field Experiment for Measurement of the Radiative Characteristics of a Hazy Atmosphere
Publisher: American Meteorological Society
Abstract: Theoretical two-and three-dimensional solutions to the radiative transfer equation have been applied to the earth-atmosphere system. A field experiment was conducted to test this theory. in the experiment the upward radiance ...
Measurement of Rainfall Rates by Lidar
Publisher: American Meteorological Society
Abstract: Monostatic lidar is explored as a means for determining the rainfall rate over an extended atmospheric path with a spatial resolution comparable to that of rain gages. An empirical relationship is established between the ...
Lidar Observations of the Convective Boundary Layer
Publisher: American Meteorological Society
Abstract: A scanning lidar system has been used to observe convection in the atmospheric boundary layer. In particular, cell sizes and geometry have been determined and circulation patterns in and around the cells have been measured. ...
The Determination of Wind Speeds in the Boundary Layer by Monostatic Lidar
Publisher: American Meteorological Society
Abstract: Vertical profiles of the horizontal radial wind component in the lowest kilometer of the atmosphere have been measured remotely with lidar. Wind speed determinations were made by observing the motion of naturally occurring ...
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) ...
Cloud Detection with MODIS. Part II: Validation
Publisher: American Meteorological Society
Abstract: An assessment of the performance of the Moderate Resolution Imaging Spectroradiometer (MODIS) cloud mask algorithm for Terra and Aqua satellites is presented. The MODIS cloud mask algorithm output is compared with lidar ...
Cirrus Cloud Radiative and Microphysical Properties from Ground Observations and In Situ Measurements during FIRE 1991 and Their Application to Exhibit Problems in Cirrus Solar Radiative Transfer Modeling
Publisher: American Meteorological Society
Abstract: Measurements from the FIRE 1991 cirrus cloud field experiment in the central United States are presented and analyzed. The first part focuses on cirrus microphysical properties. Aircraft 2D-probe in situ data at different ...
