Hydrometeor Retrieval Accuracy Using Microwave Window and Sounding Channel Observations
(American Meteorological Society, 2005)The retrieval errors of cloud and precipitation hydrometeor contents from spaceborne observations are estimated at microwave frequencies in atmospheric windows between 18 and 150 GHz and in oxygen absorption complexes near ... -
Comparison of Soil Hydraulic Parameterizations for Mesoscale Meteorological Models
(American Meteorological Society, 2005)Soil water contents, calculated with seven soil hydraulic parameterizations, that is, soil hydraulic functions together with the corresponding parameter sets, are compared with observational data. The parameterizations ... -
On the Shape–Slope Relation of Drop Size Distributions in Convective Rain
(American Meteorological Society, 2005)The relation between the slope and shape parameters of the raindrop size distribution parameterized by a gamma distribution is examined. The comparison of results of a simple rain shaft model with an empirical relation ... -
Aluminum Oxide Hygrometer: Laboratory Performance and Flight Results

Ice Cloud Retrievals and Analysis with the Compact Scanning Submillimeter Imaging Radiometer and the Cloud Radar System during CRYSTAL FACE
(American Meteorological Society, 2005)Submillimeter-wave radiometry is a new technique for determining ice water path (IWP) and particle size in upper-tropospheric ice clouds. The first brightness temperatures images of ice clouds above 340 GHz were measured ... -
Assimilation of Doppler Radar Observations with a Regional 3DVAR System: Impact of Doppler Velocities on Forecasts of a Heavy Rainfall Case
(American Meteorological Society, 2005)In this paper, the impact of Doppler radar radial velocity on the prediction of a heavy rainfall event is examined. The three-dimensional variational data assimilation (3DVAR) system for use with the fifth-generation ... -
A Survey of Temperature Measurements in Convective Clouds
(American Meteorological Society, 2005)A brief review of errors associated with aircraft measurements of temperature in cumulus clouds is presented. This analysis forms the basis for the introduction of a compilation of in-cloud temperature measurements that ... -
Dispersion of Particles Released into a Neutral Planetary Boundary Layer Using a Markov Chain–Monte Carlo Model
(American Meteorological Society, 2005)The dispersion and concentration of particles (fluid elements) that are continuously released into a neutral planetary boundary layer is presented. The velocity fluctuations of the particles are generated using a Markov ... -
Temporal and Spatial Changes of the Agroclimate in Alberta, Canada, from 1901 to 2002
(American Meteorological Society, 2005)This paper analyzes the long-term (1901?2002) temporal trends in the agroclimate of Alberta, Canada, and explores the spatial variations of the agroclimatic resources and the potential crop-growing area in Alberta. Nine ... -
Satellite-Based Imagery Techniques for Daytime Cloud/Snow Delineation from MODIS
(American Meteorological Society, 2005)This paper presents two multispectral enhancement techniques for distinguishing between regions of cloud and snow cover using optical spectrum passive radiometer satellite observations from the Moderate Resolution Imaging ... -
Error Statistics of VPR Corrections in Stratiform Precipitation
(American Meteorological Society, 2005)Errors in surface rainfall estimates that are caused by ignoring the vertical profile of reflectivity (VPR) and range effects have been assessed by simulating how fine-resolution 3D reflectivity measurements at close ranges ... -
Impact of Island-Induced Clouds on Surface Measurements: Analysis of the ARM Nauru Island Effect Study Data
(American Meteorological Society, 2005)An Atmospheric Radiation and Cloud Station (ARCS) was established on the island of Nauru by the Atmospheric Radiation Measurement (ARM) Program. Analysis of the Nauru99 field experiment data indicated that measurements at ... -
Storm Precipitation in the United States. Part II: Soil Erosion Characteristics
(American Meteorological Society, 2005)Soil erosion is a major global challenge. An increased understanding of the mechanisms driving soil erosion, especially the storms that produce it, is vital to reducing the impact on agriculture and the environment. The ... -
