Guide to Meteorological Observing and Information Distribution Systems for Aviation Weather Services

This Guide presents some of the observing systems currently available to meet the stated operational requirements in aeronautical meteorology and provides guidance on the ones deemed most appropriate under different circumstances. Where applicable, the Guide encourages the adoption of WMO/International Civil Aviation Organization (ICAO) standards. An important issue considered is the cost of the provision of observations in relation to the expected measurable benefits to be derived from a particular application.
