Evaluation of Cloud Amount Trends and their Connections to Large-Scale Dynamics

Prepared by Todd D. Ellis, Graeme Stephens, G. Garrett Campbell, and David Thompson - Colorado State University Department of Atmospheric Science

This site contains all figures related to my Masters research. Please refer to the preprint manuscript for details regarding what these figures represent and how they support the research. You can download a copy of my poster presented at the July 2004 ICCP Conference in Bologna, Italy. Any questions? Please contact me, Todd Ellis, and I'll respond as soon as I can =). As I begin preparations for publications, copies of draft reports and new figures may appear over the next few weeks.
