Direct measurements of episodic snow accumulation on the Antarctic polar plateau
(Wiley, 2000-04-27)During a 1-year field experiment at a remote location on the Antarctic polar plateau (85.67°S, 46.38°W) influenced by moderate magnitude katabatic winds, snow accumulation was characterized at three different spatial and ... -
Coherent radar ice thickness measurements over the Greenland ice sheet
(Wiley, 2001-12-27)We developed two 150-MHz coherent radar depth sounders for ice thickness measurements over the Greenland ice sheet. We developed one of these using connectorized components and the other using radio frequency integrated ... -
A detailed assessment of snow accumulation in katabatic wind areas on the Ross Ice Shelf, Antarctica
(Wiley, 1997-12-27)An investigation of time dependent snow accumulation and erosion dynamics in a wind-swept environment was undertaken at two automatic weather stations sites on the Ross Ice Shelf between January 1994 and November 1995 using ... -
Rapid ice discharge from southeast Greenland glaciers
(Wiley, 2004-03-25)[1] Interferometric synthetic-aperture radar (InSAR) observations of southeast Greenland glaciers acquired by the Earth Remote Sensing Satellites (ERS-1/2) in 1996 were combined with ice sounding radar data collected in ... -
Improvement of radar ice-thickness measurements of Greenland outlet glaciers using SAR processing
(International Glaciological Society, 2002-01-01)Extensive aircraft-based radar ice-thickness measurements over the interior and outlet-glacier regions of the Greenland ice sheet have been obtained by the University of Kansas since 1993, with the latest airborne surveys ... -
Airborne Observations of a Catalina Eddy
(American Meteorological Society, 2013-10)Summertime low-level winds over the ocean adjacent to the California coast are typically from the north, roughly parallel to the coastline. Past Point Conception the flow often turns eastward, thereby generating cyclonic ... -
Airborne Measurements of Coastal Jet Transition around Point Conception, California
(American Meteorological Society, 2013-11)Low-level winds along the Californian coast during spring and early summer are typically strong and contained within the cool, well-mixed marine boundary layer (MBL). A temperature inversion separates the MBL from the ... -
A synoptic climatology of the near-surface wind along the west coast of South America
(Royal Meteorological Society, 2013-05-20)Prevailing wind along the west coast of South America is equatorward, driven by the southeast Pacific anticyclone. The wind induces strong coastal upwelling that supports one of the most important fisheries in the world. ... -
Coastal Jet Adjustment near Point Conception, California, with Opposing Wind in the Bight
(American Meteorological Society, 2014-03)Typical spring and summer conditions offshore of California consist of strong northerly low-level wind contained within the cool, well-mixed marine boundary layer (MBL) that is separated from the warm and dry free troposphere ... -
Aircraft Observations of the Marine Boundary Layer Adjustment near Point Arguello, California
(American Meteorological Society, 2014-04)Northerly winds set up by synoptic conditions are persistent in the marine boundary layer (MBL) off the California coast from late spring through summer. Wind, pressure, and MBL height are modulated as the low-level flow ... -
Encroachment by Word, Axis, and Tree: Mapping Techniques from the Colonization of New England
(2004)It is well established that mapping has been an important tool for the colonization of North America. Techniques such as removal of toponymy, alteration of a boundary line location, and use of a map grid, were all successfully ... -
Numerical simulation of tropical cumulus congestus during TOGA COARE
(American Geophysical Union, 2013-09-17)Recent observational studies of tropical deep convection typically include some mention of cumulus congestus, a third mode of tropical convection, in addition to shallow trade cumulus and deep convection. This study analyzes ... -
Comparing Surface and Mid-Tropospheric CO2 Concentrations from Central U.S. Grasslands
(MDPI AG, 2013-02-06)Comparisons of eddy covariance (EC) tower measurements of CO2 concentration with mid-tropospheric observations from the Atmospheric Infrared Sounder (AIRS) allow for evaluation of the rising global signal of this greenhouse ... -
An inventory of glacier changes between 1973 and 2011 for the Geladandong Mountain area, China.
(European Geosciences Union, 2013-02-12)The snow and ice of the Geladangong Mountain area supply the headwaters of the Yangtze River, and long-term changes to glaciers and ice masses in this region due to a warming climate are of great concern. An inventory of ... -
Weaving Indigenous and Sustainability Sciences: Diversifying our Methods (WIS2DOM) Workshop
(2014-05-27)This report summarizes the findings of the February 13-16, 2013 workshop, entitled Weaving Indigenous and Sustainability Sciences to Diversify our Methods (WIS2DOM), held in Olympia, Washington at The Evergreen State ... -
Estimating Continental and Terrestrial Precipitation Averages from Raingauge Networks
(Royal Meteorological Society, 1994)Influences of varying rain-gauge networks on continental and terrestrial precipitation averages (derived from data observed on those networks) are evaluated. Unsystematically and systematically designed station networks ... -
An Urban Parameterization for a Global Climate Model. Part II: Sensitivity to Input Parameters and the Simulated Urban Heat Island in Offline Simulations
(American Meteorological Society, 2008)In a companion paper, the authors presented a formulation and evaluation of an urban parameterization designed to represent the urban energy balance in the Community Land Model. Here the robustness of the model is tested ... -
An Urban Parameterization for a Global Climate Model. Part I: Formulation and Evaluation for Two Cities
(American Meteorological Society, 2008)Urbanization, the expansion of built-up areas, is an important yet less-studied aspect of land use/land cover change in climate science. To date, most global climate models used to evaluate effects of land use/land cover ... -
Influence of Spatially Variable Instrument Networks on Climatic Averages
(American Geophysical Union, 1991)Instrument networks for measuring surface air temperature (T) and precipitation (P) have varied considerably over the last century. Inadequate observing‐station locations have produced incomplete, uneven, and biased samples ... -
