Meteorological hazard identification apparatus, moving craft and methods

A meteorological hazard identification apparatus performs a method comprising receiving a plurality of measurement sample tracks generated by a moving craft using a measurement device mounted on the craft and each of the measurement sample tracks comprising a plurality of captured samples of one or more meteorological parameters measured with respect to geographical co-ordinates providing a location of the captured sample. The craft may be an airborne craft such as an aircraft. The method includes storing the plurality of sample tracks into a data store, retrieving each of the measurement tracks from the data store, combining the plurality of measurement tracks, to form, with respect to mapping information, a representation at geographical locations within a region, of a variation in the one of more meteorological parameters with respect to displacement within the region, for access by one or more devices for display to users. The samples may represent cloud particle characteristics, atmospheric composition, airframe or aero-engine icing, or hazardous gases, for example.
