Stratospheric Aerosol and Gas Experiment II CD-ROM Atlas of Global Monthly Aerosols, Ozone, NO2, Water, Vapor, and Relative Humitidy (1985–1993)
(American Meteorological Society, 1997)Individual profile measurements from the Stratospheric Aerosol and Gas Experiment II (SAGE II) instrument aboard the Earth Radiation Budget Satellite have been used to create latitude-longitude maps of monthly mean aerosols, ... -
Simulation Errors Associated with the Neglect of Oceanic Salinity in an Atmospheric GCM
(American Meteorological Society, 1997)In all the atmospheric general circulation models (GCMs) at the Goddard Laboratory for Atmospheres (GLA), the influence of oceanic salinity on the saturation vapor pressure of seawater is ignored. Since the relative humidity ... -
Dynamic interaction between tectonic plates, subducting slabs, and the mantle
(American Meteorological Society, 1997)Mantle convection models have been formulated to investigate the relation between plate kinematics and mantle dynamics. The cylindrical geometry models incorporate mobile, faulted plate margins, a phase change at 670 km ... -
Multiparameter AVHRR-Derived Products for Arctic Climate Studies
(American Meteorological Society, 1997)Generation and sample applications of an integrated set of remotely sensed products for investigations of Arctic climate are described. Cloud fraction, ice surface temperature, surface albedo, downwelling radiative fluxes, ... -
Design of Total Runoff Integrating Pathways (TRIP)—A Global River Channel Network
(American Meteorological Society, 1998)As a first step toward designing a comprehensive model for validating land surface hydrology and river flow in Earth system models, a global river channel network has been prepared at 1° latitude ? 1° longitude resolution. ... -
Comparison of a Land Surface Model (SSiB) to Three Parameterizations of Evapotranspiration—A Study Based on ISLSCP Initiative I Data
(American Meteorological Society, 1998)Four different methods of estimating land surface evapotranspiration are compared by forcing each scheme with near-surface atmospheric and soil- and vegetation-type forcing data available through International Satellite ... -
The Opening of the Tasman Sea: A Gravity Anomaly Animation
(American Meteorological Society, 1998)The first plate tectonic gravity anomaly grid animation using data from the Tasman Sea is presented. In this animation the tectonic elements are represented by their respective gravity fields, based on recent marine-sate ... -
A Conterminous United States Multilayer Soil Characteristics Dataset for Regional Climate and Hydrology Modeling
(American Meteorological Society, 1998)Soil information is now widely required by many climate and hydrology models and soil?vegetation?atmosphere transfer schemes. This paper describes the development of a multilayer soil characteristics dataset for the ... -
Three-Dimensional Mantle Convection With Continental Crust: First-Generation Numerical Simulations
(American Meteorological Society, 1999)The potential effects of continental crust on mantle convection are explored using three-dimensional numerical simulations. The simulations model the coupling between a thin, deformable layer of chemically buoyant crust ... -
ENSO Effects on Gulf of Alaska Eddies
(American Meteorological Society, 1999)Generation and propagation of eddies in the coastal regions of the eastern Gulf of Alaska are examined based on ouput from a numerical ocean model. Results from a 1/8° six-layer isopycnal, wind-forced Pacific basin model ... -
Interannual Temperature Events and Shifts in Global Temperature: A “Multiwavelet” Correlation Approach
(American Meteorological Society, 2000)For the purpose of climate signal detection, we introduce a method for identifying significant episodes of large-scale oscillatory variability. The method is based on a multivariate wavelet algorithm that identifies coherent ... -
Near-Surface Site Effects in Crystalline Bedrock: A Comprehensive Analysis of Spectral Amplitudes Determined from a Dense, Three-Component Seismic Array
(American Meteorological Society, 2000)We find that site effects on weathered granodiorite bedrock at Piñon Flat in southern California are highly variable at distance scales of the order of tens of meters. We base this conclusion on 111,632 power spectral ... -
Parameterization and Sensitivity Analysis of the BIOME–BGC Terrestrial Ecosystem Model: Net Primary Production Controls
(American Meteorological Society, 2000)Ecosystem simulation models use descriptive input parameters to establish the physiology, biochemistry, structure, and allocation patterns of vegetation functional types, or biomes. For single-stand simulations it is ... -
Global Temperature Patterns in Past Centuries: An Interactive Presentation
(American Meteorological Society, 2000)The recent availability of global networks of annual or seasonal resolution proxy data, combined with the few long instrumental and historical climate records available during the past few centuries, make it possible now ... -
Refinements to SSiB with an Emphasis on Snow Physics: Evaluation and Validation Using GSWP and Valdai Data
(American Meteorological Society, 2001)Refinements to the snow-physics scheme of the Simplified Simple Biosphere Model (SSiB) are described and evaluated. The upgrades include a partial redesign of the conceptual architecture of snowpack to better simulate the ... -
Interpretation of TRMM TMI Images of Tropical Cyclones
(American Meteorological Society, 2002)Images of the 85-GHz frequency from the Special Sensor Microwave Imager (SSM/I) aboard the Defense Meteorological Satellite Program (DMSP) spacecraft are routinely viewed by forecasters for tropical cyclone analyses. These ... -
Analysis of a Mesoscale Gravity Wave Event Using Empirical Orthogonal Functions
