The items within this code table are the weather types that may be reported within a meteorological aerodrome observation report that have occurred during the period since the last issued routine report or last hour, whichever is shorter, but are not observed at the time of the observation. Requirements for reporting recent weather at an aerodrome are specified in Technical Regulations, Volume II (WMO-No. 49), Part II, Appendix 3, [C.3.1.] 4.8.1.1. This code table contains the set of weather types that are permitted for reporting recent weather.
