Citation: Machperson, I., Mengistu, W., Kustas, W., Prueger, J. 2003. Aircraft and tower-based measured fluxes over rapidly growing corn and soybean crops in central Iowa during Smacex. In: Proceedings of the Hydrology Conference, Preprint CD-ROM American Meteorological Society Annual Meeting, February 9-13, 2003.

Interpretive Summary: The Soil Moisture-Atmosphere Coupling Experiment (SMACEX) was a four-week field campaign that significantly expanded the objectives of the Soil Moisture Experiment 2002 (SMEX02). The main objective of SMEX02 was to provide data sets for the development and verification of alternate passive microwave soil moisture retrieval algorithms in a region with significant agricultural crops. SMACEX was a boundary layer experiment within SMEX02 that used the NRC Twin Otter atmospheric research aircraft, LIDARS, and an array of 14 flux towers to examine water and energy cycling across the land-atmosphere interface. In particular, the aircraft and tower data will form a multi-scale dataset with which to evaluate Land-Atmosphere-Transfer-Schemes (LATS) that have been developed to directly integrate the spatial information provided by remotely sensed data.
