Systems and methods for measuring gas flux are disclosed. One method for calculating gas flux includes: receiving a master clock signal from a global positioning system (GPS) module; transmitting a clock synchronization signal that is based on the master clock signal to a measurement subsystem configured to measure environmental data, wherein the measurement subsystem comprises at least two clocks; receiving the environmental data from the measurement subsystem, wherein the environmental data is associated with the at least two clocks; and calculating gas flux based on the environmental data received from the measurement subsystem.

A method of detecting the condition of a turf grass is described. According to one aspect of the invention, the method comprises steps of attaching an active sensor to a mower; traversing a section of turf grass; and processing the output of the sensor. A device for detecting the condition of turf grass is also disclosed. The device comprises an array of illuminating devices generating a pattern of illuminating light; a detecting device receiving a pattern of reflected light which is coincident with the pattern of illuminating light; a detecting device adapted to detect stray light from the array of illuminating devices; and a feedback loop controlling the array of illuminating devices. A system employing the device is also disclosed.
