Spectral Retrieval of Latent Heating Profiles from TRMM PR Data. Part II: Algorithm Improvement and Heating Estimates over Tropical Ocean Regions
(American Meteorological Society, 2007)The spectral latent heating (SLH) algorithm was developed for the Tropical Rainfall Measuring Mission (TRMM) precipitation radar (PR) in Part I of this study. The method uses PR information [precipitation-top height (PTH), ... -
A Polarimetric Radar Approach to Identify Rain, Melting-Layer, and Snow Regions for Applying Corrections to Vertical Profiles of Reflectivity
(American Meteorological Society, 2007)This article describes polarimetric X-band radar-based quantitative precipitation estimations (QPE) under conditions of low freezing levels when, even at the lowest possible elevation angles, radar resolution volumes at ... -
Sea Surface Winds over the Mediterranean Basin from Satellite Data (2000–04): Meso- and Local-Scale Features on Annual and Seasonal Time Scales
(American Meteorological Society, 2007)This paper investigates the mean spatial features of the winds in the Mediterranean and Black Seas using the wind fields observed by the SeaWinds scatterometer. Five years (2000?04) of data have been analyzed on annual and ... -
Temperate Mountain Glacier-Melting Rates for the Period 2001–30: Estimates from Three Coupled GCM Simulations for the Greater Himalayas
(American Meteorological Society, 2007)The temperate glaciers in the greater Himalayas (GH) and the neighboring region contribute to the freshwater supply for almost one-half of the people on earth. Under global warming conditions, the GH glaciers may melt more ... -
Single-Scattering Properties of Aggregates of Bullet Rosettes in Cirrus
(American Meteorological Society, 2007)During the March 2000 Cloud Intensive Operational Period, the University of North Dakota Citation executed spiral descents through midlatitude cirrus of a nonconvective origin over the Atmospheric Radiation Measurement ... -
Real-Time Comparisons of VPR-Corrected Daily Rainfall Estimates with a Gauge Mesonet
(American Meteorological Society, 2007)The relative skill of two vertical-profile-of-reflectivity (VPR) correction techniques for daily accumulations on a selected dataset and a real-time dataset has been verified. The first technique (C1) adjusts the 1-h ... -
Estimation of Daylight Downward Longwave Atmospheric Irradiance under Clear-Sky and All-Sky Conditions
(American Meteorological Society, 2007)Daylight downward longwave irradiance data recorded over a flat place for the period between April 2001 and December 2004 in Valladolid, Spain, have been compared with estimates generated using four different schemes. The ... -
Statistical Error Decomposition of Regional-Scale Climatological Precipitation Estimates from the Tropical Rainfall Measuring Mission (TRMM)
(American Meteorological Society, 2007)Monthly rainfall estimates inferred from the NASA Tropical Rainfall Measuring Mission (TRMM) satellite contain errors due to discrete temporal sampling and remote spaceborne rain retrievals. This paper develops a regional-scale ... -
Roughness Lengths for Momentum and Heat Derived from Outdoor Urban Scale Models
(American Meteorological Society, 2007)Urban climate experimental results from the Comprehensive Outdoor Scale Model (COSMO) were used to estimate roughness lengths for momentum and heat. Two different physical scale models were used to investigate the scale ... -
Urban Aerosol Impacts on Downwind Convective Storms
(American Meteorological Society, 2007)The impacts of urban-enhanced aerosol concentrations on convective storm development and precipitation over and downwind of St. Louis, Missouri, are investigated. This is achieved through the use of a cloud-resolving ... -
A Review and Comparison of Changepoint Detection Techniques for Climate Data
(American Meteorological Society, 2007)This review article enumerates, categorizes, and compares many of the methods that have been proposed to detect undocumented changepoints in climate data series. The methods examined include the standard normal homogeneity ... -
Flow Variability in a North American Downtown Street Canyon
(American Meteorological Society, 2007)Previous field and laboratory studies have indicated that flow and turbulence inside urban areas and, in particular, in street canyons, is very complex and is associated with wakes and vortices developing near buildings. ... -
Downscaling of Seasonal Precipitation for Crop Simulation
(American Meteorological Society, 2007)A nonhomogeneous hidden Markov model (NHMM) is used to make stochastic simulations of March?August daily rainfall at 10 stations over the southeastern United States, 1923?98. Station-averaged observed daily rainfall amount ... -
Interchannel Error Correlation Associated with AIRS Radiance Observations: Inference and Impact in Data Assimilation
(American Meteorological Society, 2007)The interchannel observation error correlation (IOEC) associated with radiance observations is currently assumed to be zero in meteorological data assimilation systems. This assumption may lead to suboptimal analyses. Here, ... -
