This project will perform a preliminary assessment of climate effects on human health in Iowa. A database will be compiled which consists of a historical fifty year record of daily meteorological factors (temperature, relative humidity, etc.) consisting of one site per county, along with meteorological quantities predicted for future climates based on Global Climate Model (GCM) results. Basic health-related weather quantities will be derived (heat stress index), and will be made available for studies relating weather attributes to morbidity and mortality. The data set will then be used in a preliminary assessment of the future risks associated with climate change. This will be accomplished by combining this data set with population and health-related statistics (hospital admissions, deaths by disease/cause, etc.)
