Monthly Changes in Atmospheric Carbon Dioxide at Mauna Loa: Possible Asymmetric Effects of Warming
(American Meteorological Society, 2007)Changes in the intra-annual cycle of atmospheric CO2 at Mauna Loa, Hawaii, are investigated by comparing monthly observations to the mean value of each year?s waxing and waning phase of the cycle. Results identify a ... -
The Effects of Different Climate Input Datasets on Simulated Carbon Dynamics in the Western Arctic
(American Meteorological Society, 2007)As part of the Western Arctic Linkage Experiment (WALE), simulations of carbon dynamics in the western Arctic (WALE region) were conducted during two recent decades by driving the Terrestrial Ecosystem Model (TEM) with ... -
Terrestrial Carbon Sinks for the United States Predicted from MODIS Satellite Data and Ecosystem Modeling
(American Meteorological Society, 2007)A simulation model based on satellite observations of monthly vegetation cover from the Moderate Resolution Imaging Spectroradiometer (MODIS) was used to estimate monthly carbon fluxes in terrestrial ecosystems of the ... -
Regional Characterization of Pasture Changes through Time and Space in Rondônia, Brazil
(American Meteorological Society, 2007)Although pasture degradation has been a regional concern in Amazonian ecosystems, our ability to characterize and monitor pasture degradation under different environmental and human-related conditions is still limited. ... -
Spatiotemporal Variations in Growing Season Exchanges of CO2, H2O, and Sensible Heat in Agricultural Fields of the Southern Great Plains
(American Meteorological Society, 2007)Climate, vegetation cover, and management create finescale heterogeneity in unirrigated agricultural regions, with important but not well-quantified consequences for spatial and temporal variations in surface CO2, water, ... -
A Simple Predictive Tool for Lower Brahmaputra River Basin Monsoon Flooding
(American Meteorological Society, 2007)The Brahmaputra River of South Asia is the fourth largest river in the world in terms of annual discharge. The lower Brahmaputra River basin is susceptible to catastrophic flooding with major social, economic, and public ... -
Basin-Scale Carbon Monoxide Distributions in the Parallel Ocean Program
(American Meteorological Society, 2007)As a primary photochemical constituent in upper-ocean and tropospheric geocycling, carbon monoxide is of interest to a variety of global change research communities. Dynamic three-dimensional simulations of its marine ... -
Hydrological Impacts of Deforestation on the Southeast Tibetan Plateau
(American Meteorological Society, 2007)The hydrological impact of forest removal on the southeast Tibetan Plateau during the second half of the last century is investigated in this study using an atmospheric general circulation model. The effects of deforestation ... -
Poisonous Effects of Asteroid Impacts or Nuclear Explosions in the Western Regions of the Black Sea
(American Meteorological Society, 2007)The impact of an asteroid or a very large nuclear explosion in the Black Sea may cause a poisonous hydrogen sulfide gas release into the atmosphere. Some effects of this phenomenon on the western Black Sea coasts are ... -
Intraseasonal Interactions between Temperature and Vegetation over the Boreal Forests
(American Meteorological Society, 2007)This paper uses statistical and analytical techniques to investigate intraseasonal interactions between temperature and vegetation [surrogated by the normalized difference vegetation index (NDVI)] over the boreal forests. ... -
Spatiotemporal Climate Model Validation—Case Studies for MM5 over Northwestern Canada and Alaska
(American Meteorological Society, 2007)The Western Arctic Linkage Experiment (WALE) is aimed at understanding the role of high-latitude terrestrial ecosystems in the response of the Arctic system to global change through collection and comparison of climate ... -
Water Balance for the Ji-Paraná River Basin, Western Amazon, Using a Simple Method through Geographical Information Systems and Remote Sensing
(American Meteorological Society, 2007)The Thornthwaite?Mather climatological model integrated into a Geographic Information System (GIS) was used to simulate the monthly water balance for the Ji-Paraná river basin, in the western Amazonian state of Rondônia ... -
Comparative Analysis of the Western Arctic Surface Climate among Observations and Model Simulations
(American Meteorological Society, 2007)Accurate estimates of the spatial and temporal variation in terrestrial water and energy fluxes and mean states are important for simulating regional hydrology and biogeochemistry in high-latitude regions. Furthermore, it ... -
Dynamic Fire Danger Mapping from Satellite Imagery and Meteorological Forecast Data
(American Meteorological Society, 2007)This study aims at ascertaining if and how remote sensing data can improve fire danger estimation based on meteorological variables. With this goal in mind, a dynamic estimation of fire danger was performed using an approach ... -
Deforestation Hotspots in the Brazilian Amazon: Evidence and Causes as Assessed from Remote Sensing and Census Data
(American Meteorological Society, 2007)The main goal of this study, conducted in an area comprising 221 municipalities, in which 90% of the deforestation in the Legal Amazon takes place, was to understand the role of the agrarian structure in the conversion of ... -
Plant Species Distributions under Present Conditions and Forecasted for Warmer Climates in an Arid Mountain Range
(American Meteorological Society, 2007)Complex environmental gradients in the White and Inyo Mountains in eastern California produce striking variations in vegetation assemblages over short distances. Vegetation composition is dominated by elevational gradients ... -
An Analytical Hydrological Model for the Study of Scaling Issues in Land Surface Modeling
