The Kenaston Evaporation and Evapotranspiration Flux Experiment (KEEFEX), located approximately 90km south of Saskatoon, Saskatchewan, Canada, was initiated in 2009 to examine the relative local moisture contribution from crops and natural (short grass) pasture. The study was prompted by the requirement to examine localized differences in evaporation and evapotranspiration from various land surface types that could be linked to the development, timing (diurnal and seasonal), and severity of convective storms. Results will also be beneficial for refining surface parameterization schemes in land surface models. The KEEFEX instrumentation includes concurrent eddy covariance surface flux measurements as well as temperature and humidity profiles in a grassed pasture and agricultural crops located less than 2km apart. This presentation will provide an overview of the research project and summarize some of the results obtained from the 2009, 2010, and 2011 field seasons.
