AB: This paper provides an examination of how smart sensory arrays can be used to study complex, interwoven environmental and meteorological processes. We begin with a summary of challenges researchers confront as they attempt to combine various measurements and modeling approaches into integrated land-atmosphere views. We describe land-atmosphere process models in general. We propose an architecture of sensors arrays that will incorporate land-atmosphere processes, their interactions and scale. A set of system design requirements are developed that convert the hardware design of the sensor nodes, the design of the sensor network and the capabilities for remote data access and management into a configuration suitable for land-atmosphere research. We present a specific instance of the architecture for monitoring carbon sequestration in subalpine forests. The proposed deployed network will consist of 320 microscale nodes, 9 mesoscale nodes and 2 network nodes. The application driven design exercise serves to identify important areas of further work in data sampling, communications, network retasking and health monitoring. Key Works : Array - collection of sensors in a network; Cluster - a dynamic connection of higher-level nodes with local lower-level nodes; Event - Internally generated or externally received diagnostic (including network), sensed or derived signal requiring response evaluation; Microscale -spatial scales 10 meters or less; Mesoscale - spatial scales 10 meters to 10 kilometers; Node - physical and conceptual model of a sensor in a network; Sensor - combination of one or more transducers, a data input/output(I/O) component, a power component, and a transmitter component; Transducer - sensor component that converts state property (temperature, humidity) to electronic signal. Examples: thermister, capacitive moisture transducer, etc.
