Sensitivity of climate forcing and response to dust optical properties in an idealized model

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...

Direct radiative effect of mineral dust and volcanic aerosols in a simple aerosol climate model

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...

Constraining recent lead pollution sources in the North Pacific using ice core stable lead isotopes

Creator:: Gross, B. H., Kreutz, K. J., Osterberg, E. C., McConnell, J. R., Handley, M., Wake, C. P., and Yalcin, K.
Abstract:: Trends and sources of lead (Pb) aerosol pollution in the North Pacific rim of North America from 1850 to 2001 are investigated using a high-resolution (subannual to annual) ice core record recovered from Eclipse Icefield (3017 masl; St. Elias Mountains, Canada). Beginning in the early 1940s, increasing Pb concentration at...

Observation of playa salts as nuclei in orographic wave clouds

Creator:: Pratt, Kerri A., Twohy, Cynthia, Murphy, Shane M., Moffet, Ryan C., Heymsfield, Andrew J., Gaston, Cassandra J., DeMott, Paul J., Field, Paul R., Henn, Tobias R., Rogers, David C., Gilles, Mary K., Seinfeld, John H., and Prather, Kimberly A.
Abstract:: During the Ice in Clouds Experiment‐Layer Clouds (ICE‐L), dry lakebed, or playa, salts from the Great Basin region of the United States were observed as cloud nuclei in orographic wave clouds over Wyoming. Using a counterflow virtual impactor in series with a single‐particle mass spectrometer, sodium‐potassium‐magnesium‐calcium‐chloride salts were identified as...

Injection of carbon from the shelf to offshore beneath the euphoic zone in the California Current

Creator:: Barth, John A., Cowles, Timothy J., Kosro, P. Michael, 1951-, Shearman, R. Kipp, Huyer, Adriana, 1945-, and Smith, Robert L. (Robert Lloyd), 1935-
Abstract:: High concentrations of chlorophyll are found in the California Current System over 300 km offshore, far from the productive coastal upwelling region, and between 150 and 250 m, well below the depth to which photosynthetically active solar radiation penetrates. This exceptionally deep chlorophyll feature is formed near the coast and...

Currents and water masses of the coastal transition zone off Northern California, June to August 1988

Creator:: Huyer, Adriana, 1945-, Kosro, P. Michael, 1951-, Fleischbein, Jane, Ramp, Steven R., Stanton, Tim, Washburn, Libe, Chavez, Francisco P., Cowles, Timothy J., Pierce, Stephen D., and Smith, Robert L. (Robert Lloyd), 1935-
Abstract:: In summer 1988, we made repeated mesoscale surveys of a grid extending 200 km offshore between 37°N and 39°N in the coastal transition zone off northern California, obtaining continuous acoustic Doppler current profiler data and conductivity-temperature-depth data at standard stations 25 km apart on alongshore sections 40 km apart. All...

Coastal ocean response to summer upwelling favorable winds in a region of alongshore bottom topography variations off Oregon

Creator:: Castelao, Renato M. and Barth, John A.
Abstract:: Repeated mesoscale surveys of waters over the shelf and slope off Oregon were conducted during spring and summer of 2001 to study the spatial structure of the velocity and hydrographic fields. The ocean response to wind forcing is compared between a region of relatively simple topography with alongshore uniformity and...

Mesoscale surveys over the shelf and slope in the upwelling region near Point Arena, California

Creator:: Huyer, Adriana, 1945- and Kosro, P. Michael, 1951-
Abstract:: Repeated mesoscale surveys of a 40-km-wide, 100-km-long, coastal region near Point Arena, California, were conducted during the upwelling season (April-August) in 1981 and 1982. Each survey included conventional conductivity-temperature-depth casts at standard locations over the continental shelf and slope between 38°N and 39°10'N, and continuous operation of a Doppler acoustic...

Sea surface temperature fronts in the California Current System from geostationary satellite observations

Creator:: Castelao, Renato M., Mavor, Timothy P., Barth, John A., and Breaker, Laurence C.
Abstract:: Sea surface temperature (SST) fronts are determined for the 2001–2004 time period from Geostationary Operational Environmental Satellites (GOES) data in the California Current System (CCS). The probability of detecting a SST front at an individual pixel location in the CCS is presented as a bi-monthly climatology. Fronts clearly indicate the...

Assessment of new production at the upwelling center at Point Conception, California, using nitrate estimated from remotely sensed sea surface temperature

Creator:: Dugdale, Richard C., Davis, Curtiss O., and Wilkerson, Frances P.
Abstract:: Remotely sensed sea surface temperature (SST) and a model originally developed for Cap Blanc, northwest Africa [Dugdale et al., 1989], are used to estimate new production (i.e., nitrate uptake, in the sense of Dugdale and Goering [1967]) for the persistent coastal upwelling feature at Point Conception, California. Parameters required to...
