Measurements for the SMEX02 campaign were collected throughout the state of Iowa, USA. The main objectives of the experiment were to: study land/atmosphere interactions and extend remote sensing observations and algorithms to more challenging vegetation conditions than previously studied; validate AMSR-E satellite brightness temperature and soil moisture measurement; and evaluate new instrument technologies for soil moisture remote sensing.

The photograph to the right shows the team that worked on the SMEX02 regional watershed project. The SMEX02 Field Experiment Sites Map shown below is an interactive map displaying the regional distribution of all experiment sites throughout the state of Iowa, USA.
