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, ... -
The Santa Ana Winds of California
(American Meteorological Society, 2003)A 33-yr, numerical dataset of the occurrence of Santa Ana winds for the period 1968?2000 has been created and validated. Daily Weather Maps were examined to identify the days when a surface high pressure system existed ... -
The Principal Physical Modes of Variability over the Tropical Pacific
(American Meteorological Society, 2003)The structures of the two principal modes of sea surface temperature (SST) variability were extracted by conducting cyclostationary EOF (CSEOF) analysis and regression analysis on several key variables. The CSEOF analysis ... -
Regional Modeling of Ammonia Emissions from Native Soil Sources in California
(American Meteorological Society, 2003)The development of a new emissions inventory of ammonia volatilization from native soil sources (excluding direct emissions from fertilizer application sources) for the state of California is discussed. Because a comprehensive ... -
Positive Feedback and System Resilience from Graphical and Finite-Difference Models: The Amazon Ecosystem—An Example
(American Meteorological Society, 2003)Positive feedback has the potential to create multiple steady states that divide system space into regions of distinct behavioral modes. Graphical analysis can be used to recognize systems likely to behave in this way. For ... -
Modeling Terrestrial Biogenic Sources of Oxygenated Organic Emissions
(American Meteorological Society, 2003)In recent years, oxygenated volatile organic chemicals (OVOCs) like acetone have been recognized as important atmospheric constituents due to their ability to sequester reactive nitrogen in the form peroxyacetyl nitrate ... -
Monitoring North Pacific Heat Content Variability: An Indicator of Fish Quantity?
(American Meteorological Society, 2003)Fields of modeled sea surface heights and temperatures are used to develop an algorithm to monitor the low-frequency heat content variability of the North Pacific's midlatitudes associated with regime shifts in the circulation ... -
Inferring Climate Change from Underground Temperatures: Apparent Climatic Stability and Apparent Climatic Warming
(American Meteorological Society, 2003)Data are used to demonstrate two effects apparent in ground surface temperature histories coming from inversions of borehole temperatures: apparent climatic warming and apparent climatic stability. Unrecognized local terrain ... -
Global Percent Tree Cover at a Spatial Resolution of 500 Meters: First Results of the MODIS Vegetation Continuous Fields Algorithm
(American Meteorological Society, 2003)The first results of the Moderate Resolution Imaging Spectroradiometer (MODIS) vegetation continuous field algorithm's global percent tree cover are presented. Percent tree cover per 500-m MODIS pixel is estimated using a ... -
Evaluation of a Process-Based Agro-Ecosystem Model (Agro-IBIS) across the U.S. Corn Belt: Simulations of the Interannual Variability in Maize Yield
(American Meteorological Society, 2003)A process-based terrestrial ecosystem model, Agro-IBIS, was used to simulate maize yield in a 13-state region of the U.S. Corn Belt from 1958 to 1994 across a 0.5° terrestrial grid. For validation, county-level census [U.S. ... -
Detection of Urban-Induced Rainfall Anomalies in a Major Coastal City
(American Meteorological Society, 2003)There is increasing evidence that large coastal cities, like Houston, Texas, can influence weather through complex urban land use?weather?climate feedbacks. Recent work in the literature establishes the existence of enhanced ... -
Calculation of the Energy Budget for Heterogeneous Land Surfaces
(American Meteorological Society, 2003)In this paper a scheme is presented for calculating the land surface energy budget based on the first law of thermodynamics. It takes into account the effects of water multiphase changes and hydrologic process. The enthalpy ... -
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, ... -
A Representation of Variable Root Distribution in Dynamic Vegetation Models
(American Meteorological Society, 2003)Root distribution is treated as a static component in most current dynamic vegetation models (DVMs). While changes in leaf and stem biomass are reflected in leaf area index (LAI) and vegetation height via specific leaf ... -
Analysis of Geostationary Satellite Imagery Using a Temporal-Differencing Technique
(American Meteorological Society, 2003)A new and innovative cloud analysis technique has been developed that exploits the temporal information content of geostationary satellite imagery. The algorithm is designed to identify new cloud development and moving ... -
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
(American Meteorological Society, 2002)A method is detailed that filters mesoscale gravity wave signals from synoptic-level observation data using empirical orthogonal functions (EOFs). Similar EOF analyses have been used to study many oceanographic and ... -
Refinements to SSiB with an Emphasis on Snow Physics: Evaluation and Validation Using GSWP and Valdai Data
