A ship-borne meteorological station for ground truth measurements
Abstract
Oceanographic upwelling studies required ground truth measurements of meteorological parameters and sea surface temperature to be made from a research vessel which did not have the necessary facilities. A ship-borne station was therefore designed to sense and store standard meteorological parameters wich special reference to wind data. The system was based on a 16 bit microprocessor. Commercial sensors with half bridge outputs were used. All sensor outputs were converted to engineering units using best fit third order polynomials prior to storage. The system was calibrated in the laboratory and also after installation. Results obtained from the system met the required specifications. The exercise of constructing a weather station has demonstrated that with the high performance components available, and modular software construction in a Higher Level Language, it is possible to design equipment specially tailored to ones needs, rapidly and cost effectively
