IEM Update: From pollen to rivers to pavements to soils and a whole lot more. The Iowa Environmental Mesonet (IEM) was created back in 2001 with the vision of providing an one stop shop for environmental data for the state of Iowa. This data has been collected from partners providing access to their datasets. To date, the IEM has collected nearly 1 billion observations. The goal of assembling such a large and diverse dataset was to spur cross discipline research and collaboration. Such research projects include the modellling of maize pollen dispersion, forecasting the river stage on Squaw Creek, modelling roadway wear, and analysis of statewide soil erosion. This talk presents an update on these research projects and a whole lot more.
