Effects of Aerosols on the Radiative Properties of Clouds

Creator:: Taylor, Jonathan P., Glew, Martin D., Coakley, James A., Jr., Tahnk, William R., Platnick, Steven, Hobbs, Peter V., and Ferek, Ronald J.
Abstract:: The influence of anthropogenic aerosols, in the form of ship exhaust effluent, on the microphysics and radiative properties of marine stratocumulus is studied using data gathered from the U.K. Met. Office C-130 and the University of Washington C-131A aircraft during the Monterey Area Ship Track (MAST) experiment in 1994. During...

The Appearance and Disappearance of Ship Tracks on Large Spatial Scales

Creator:: Coakley, J. A., Jr., Durkee, P. A., Nielsen, K., Taylor, J. P., Platnick, S., Albrecht, B. A., Babb, D., Chang, F. L., Tahnk, W. R., Bretherton, C. S., and Hobbs, P. V.
Abstract:: The 1-km advanced very high resolution radiometer observations from the morning, NOAA-12, and afternoon, NOAA-11, satellite passes over the coast of California during June 1994 are used to determine the altitudes, visible optical depths, and cloud droplet effective radii for low-level clouds. Comparisons are made between the properties of clouds...

Observations of Stratocumulus Clouds and Their Effect on the Eastern Pacific Surface Heat Budget along 20 degrees S

Creator:: de Szoeke, Simon P., Yuter, Sandra, Mechem, David, Fairall, Chris W., Burleyson, Casey D., and Zuidema, Paquita
Abstract:: Widespread stratocumulus clouds were observed on nine transects from seven research cruises to the southeastern tropical Pacific Ocean along 20°S, 75°–85°W in October–November of 2001–08. The nine transects sample a unique combination of synoptic and interannual variability affecting the clouds; their ensemble diagnoses longitude–vertical sections of the atmosphere, diurnal cycles...

Internal transcribed spacer region evolution in Larix and Pseudotsuga (Pinaceae)

Creator:: Gernandt, David S. and Liston, Aaron
Abstract:: The nuclear ribosomal DNA (nrDNA) internal transcribed spacer (ITS) region has been characterized in the sister genera Larix and Pseudotsuga (Pinaceae). Complete sequences were obtained for seven species of Larix from North America and Eurasia and five species of Pseudotsuga from western North America and eastern Asia. ITS region lengths...

Enhancement of cloud cover and suppression of nocturnal drizzle in stratocumulus polluted by haze

Creator:: Ackerman, A. S., Toon, O. B., Stevens, D. E., and Coakley, James A., Jr.
Abstract:: Recent satellite observations indicate a significant decrease of cloud water in ship tracks, in contrast to an ensemble of in situ ship-track measurements showing no average change in cloud water relative to the surrounding clouds, and contrary to the expectation of cloud water increasing in polluted clouds. We find through...

Evaluating WRF-Chem aerosol indirect effects in Southeast Pacific marine stratocumulus during VOCALS-REx

Creator:: Saide, P. E., Spak, S. N., Carmichael, G. R., Mena-Carrasco, M. A., Yang, Q., Howell, S., Leon, D. C., Snider, J. R., Bandy, A. R., Collett, J. L., Benedict, K. B., de Szoeke, Simon P., Hawkins, L. N., Allen, G., Crawford, I., Crosier, J., and Springston, S. R.
Abstract:: We evaluate a regional-scale simulation with the WRF-Chem model for the VAMOS (Variability of the American Monsoon Systems) Ocean-Cloud-Atmosphere-Land Study Regional Experiment (VOCALS-REx), which sampled the Southeast Pacific's persistent stratocumulus deck. Evaluation of VOCALS-REx ship-based and three aircraft observations focuses on analyzing how aerosol loading affects marine boundary layer (MBL)...

Repeat intercontinental dispersal and Pleistocene speciation in disjunct Mediterranean and desert Senecio (Asteraceae)

Creator:: Coleman, Max, Liston, Aaron, Kadereit, Joachim W., and Abbott, Richard J.
Abstract:: To explore the biogeographic history of Mediterranean/arid plant disjunctions, Old and New World Senecio sect. Senecio were analyzed phylogenetically using nuclear ribosomal DNA sequences (ITS). A clade corresponding to sect. Senecio was strongly supported. Area optimization indicated this clade to be of southern African origin. The Mediterranean and southern African...

The CALIPSO Mission: A Global 3D View of Aerosols and Clouds

Creator:: Winker, D. M., Pelon, J., Coakley, J. A. Jr., Ackerman, S. A., Charlson, R. J., Colarco, P. R., Flamant, P., Fu, Q., Hoff, R. M., Kittaka, C., Kubar, T. L., Le Treut, H., McCormick, M. P., Megie, G., Poole, L., Powell, K., Trepte, C., Vaughan, M. A., and Wielicki, B. A.
Abstract:: Aerosols and clouds have important effects on Earth's climate through their effects on the radiation budget and the cycling of water between the atmosphere and Earth's surface. Limitations in our understanding of the global distribution and properties of aerosols and clouds are partly responsible for the current uncertainties in modeling...
