Definition

Sensor webs are networks of sensors that can operate in a coordinated fashion, for example, through centralized or decentralized control centers. The controller can command the sensor nodes to modify their measurement schedule or configuration in response to environmental factors or to achieve certain measurement goals. Sensor webs are envisioned as a means of providing spatially and temporally adaptive in situ measurements for validation of remote sensing observations.

Introduction

Satellite remote sensing often results in data and retrieved geophysical products with resolutions that are significantly coarser than the scale of variations of the phenomena they represent. As an example of a geophysical variable, soil moisture fields retrieved from satellite observations using microwave instruments have resolutions on the order of kilometers if not coarser. However, the soil moisture fields themselves...
