Creator:: Shell, Karen M. and Somerville, Richard C. J.
Abstract:: An idealized global climate model is used to explore the response of the climate to a wide range of dust radiative properties and dust layer heights. The top-of-the-atmosphere (TOA) shortwave forcing becomes more negative as the broadband shortwave single scattering albedo increases and the broadband shortwave asymmetry parameter decreases, but...

Creator:: Shell, Karen M. and Somerville, Richard C. J.
Abstract:: Airborne mineral dust can influence the climate by altering the radiative properties of the atmosphere, but the magnitude of the effect is uncertain. An idealized global model is developed to study the dust-climate system. The model determines the dust longwave and shortwave direct radiative forcing, as well as the resulting...

Abstract:: This paper shows a small sampling of the atmospheric fields provided by the Moderate Resolution Imaging Spectroradiometer (MODIS), which is installed on both the Terra and Aqua satellites of the Earth Observing System. These fields include macroscale fields like cloud fraction, cloud top pressure, cloud optical depth, and column water...

Creator:: Fetter, Antonio F. and Mantano, Richard P.
Abstract:: This article investigates the origins of the variability of the Malvinas Current (MC) transport using the results of an eddy-permitting ocean general circulation model. First, the dynamical links between the variabilities of the MC and the Antarctic Circumpolar Current (ACC) transports at the Drake Passage are established. Time series analyses...

Abstract:: In tidally dominated deltas, sediment discharged from the river sources must transit through an estuarine region located within the distributary channels, where particle pathways can undergo significant transformations. Water column profiles and time series data were collected in the distributaries and shallow nearshore region offshore of the Fly River, Papua...

Creator:: Ahn, Jinho, Wahlen, Martin, Deck, Bruce L., Brook, Edward J., Mayewski, Paul A., Taylor, Kendrick C., and White, James W. C.
Abstract:: We have measured the CO₂ concentration of air occluded during the last 40,000 years in the deep Siple Dome A (hereafter Siple Dome) ice core, Antarctica. The general trend of CO₂ concentration from Siple Dome ice follows the temperature inferred from the isotopic composition of the ice and is mostly...

Abstract:: Nitrate concentrations, chlorophyll a (Chl a) fluorescence, radiance, salinity, and temperature were measured on the Hawaii Air-Sea Logging Experiment, A Long-Term Oligotrophic Habitat Assessment (HALE ALOHA) mooring located near the Hawaii Ocean Time-Series (HOT) Program’s Station ALOHA (22°45’N; 158°W). Nitrate concentrations were determined with OsmoAnalyzers deployed at depths of 120...

Abstract:: We analyzed 7 years (2002–2008) of micrometeorological and concurrent biological observations of carbon and water fluxes at a mature ponderosa pine forest in central Oregon in a semiarid climate. We sought to evaluate the extent that gross primary productivity, net ecosystem exchange, ecosystem respiration, net primary productivity, net ecosystem productivity,...
