Time Modeling of Daily UVB Values in Madrid, Spain
(American Meteorological Society, 2000)This paper presents the daily solar ultraviolet-B (UVB) values measured in Madrid, Spain, during the period 1994?97 with a Brewer MKIV spectrophotometer. The range of the measured values was 0.042?6.41 kJ m?2. A description ... -
Artificial Neural Networks and Long-Range Precipitation Prediction in California
(American Meteorological Society, 2000)Artificial neural networks (ANNs), which are modeled on the operating behavior of the brain, are tolerant of some imprecision and are especially useful for classification and function approximation/mapping problems, to ... -
An AVHRR Multiple Cloud-Type Classification Package
(American Meteorological Society, 2000)Using imagery from NOAA?s Advanced Very High Resolution Radiometer (AVHRR) orbiting sensor, one of the authors (RLB) earlier developed a probabilistic neural network cloud classifier valid over the world?s maritime regions. ... -
A Comparison of Exhaust Condensation Trail Forecast Algorithms at Low Relative Humidity
(American Meteorological Society, 2000)The Schrader and Schumann contrail forecast algorithms and a third algorithm are evaluated under low relative humidity conditions using a dataset of asynoptic atmospheric soundings and 318 coincident ground-based aircraft ... -
A 10-yr Climatology of Amazonian Rainfall Derived from Passive Microwave Satellite Observations
(American Meteorological Society, 2000)In this study, a satellite-derived precipitation ?climatology? (climate description) over northern South America using a passive microwave technique, the Goddard Profiling algorithm, is presented. The results are statistically ... -
A Satellite-Derived Upper-Tropospheric Water Vapor Transport Index for Climate Studies
(American Meteorological Society, 2000)A new approach is presented to quantify upper-level moisture transport from geostationary satellite data. Daily time sequences of Geostationary Operational Environmental Satellite GOES-7 water vapor imagery were used to ... -
A First-Order Closure for Covariances and Fluxes of Reactive Species in the Convective Boundary Layer
(American Meteorological Society, 1999)Covariances and fluxes of reactive species in the clear convective atmospheric boundary layer (CABL) are studied and parameterized. The covariances result from correlations between reactive species. These covariances may ... -
CORRIGENDUM

A Study on the Relation between Terminal Velocity and VHF Backscatter from Precipitation Particles Using the Chung-Li VHF Radar
(American Meteorological Society, 1999)The relationships between the mean Doppler terminal velocities VT of the hydrometeors with different phases and the range-corrected VHF backscatter P from the corresponding precipitation particles are investigated by using ... -
Coastal Winds in South Florida
(American Meteorological Society, 1999)Thirteen-month records for the period of April 1994?April 1995 from eight (out of nine) Coastal-Marine Automatic Network (C-MAN) stations in south Florida are analyzed statistically to study alongshore variability of ... -
The Role of Vertical Mixing in the Temporal Evolution of Ground-Level Ozone Concentrations
(American Meteorological Society, 1999)Aircraft measurements taken during the North American Research Strategy for Tropospheric Ozone-Northeast field study reveal the presence of ozone concentration levels in excess of 80 ppb on a regional scale in the nocturnal ... -
Estimation of Surface Solar Global Radiation from NOAA AVHRR Data in High Latitudes
(American Meteorological Society, 1999)A physical method for estimating the instantaneous global irradiance and daily cumulative insolation based on Advanced Very High Resolution Radiometer data was developed and tested at high latitudes in a boreal subarctic ... -
Data and Approaches for Determining Hail Risk in the Contiguous United States
(American Meteorological Society, 1999)Rapidly increasing hail damages to property have brought average annual losses to $1.2 billion (in 1997-adjusted dollars) during the 1990s; this rise in loss exposure has created great concern in the insurance industry and ... -
An Observations-Based Statistical System for Warm-Season Hourly Probabilistic Forecasts of Low Ceiling at the San Francisco International Airport
(American Meteorological Society, 1999)A computational system that uses statistical equations to forecast hourly probabilities of marine stratus burn-off (via ceiling) at the San Francisco International Airport for 1?6-h lead times is developed. The system is ... -
Albedo Influences on Surface UV Irradiance at the Sonnblick High-Mountain Observatory (3106-m Altitude)
(American Meteorological Society, 1999)In this work the influences of ozone, aerosols, and albedo on the clear sky UVA and UVB irradiance at a high-mountain station are investigated by using both routine spectral UV measurements from the high-mountain Sonnblick ... -
Principal Length Scales in Second-Order Closure Models for Canopy Turbulence
(American Meteorological Society, 1999)Triaxial sonic anemometer velocity measurements vertically arrayed at six levels within and above a pine forest were used to examine the performance of two second-order closure models put forth by Wilson and Shaw and by ... -
Inclusion of a Third Soil Layer in a Land Surface Scheme Using the Force–Restore Method
(American Meteorological Society, 1999)The inclusion of a third soil layer in the Interactions between Soil, Biosphere, and Atmosphere (ISBA) model is presented in this paper. The soil water content between the base of the root zone and the deep soil layer is ... -
Estimation of Regional Evapotranspiration through Remote Sensing
(American Meteorological Society, 1999)Models used for the remote estimation of evapotranspiration are evaluated using aircraft observations over two distinct vegetation regimes in southwestern Australia. Single-source models using an empirically determined ... -
