To meet today's need for more surface measurements wireless communication technology must be incorporated. Hardwired communication prohibits the ability to deploy large arrays of multiple sensors in a timely fashion and inhibits opportunities to deploy instruments in optimum locations per the needs of sensing. WISARD was a development which incorporated wireless technology with two sets of measurements: (1) solar radiation, and (2) soil parameters. A second goal in the development was to demonstrate the concept of distributed processing by dedicating a microprocessor to each sensor. This paper presents some of the technical challenges encountered, the technology used, and the results of a successful deployment during a winter field deployment.
