METEOROLOGICAL TECHNIQUES - AIR FORCE HANDBOOK 15-101 November 2019 This handbook marks the first formal publication of a long-lived and highly-esteemed reference in the Air Force Weather community; it is a new publication, derived from the legacy Field Operating Agency Technical Note 98/002, Meteorological Techniques, and supersedes all existing iterations of the legacy document. The transition from informal tech note to formal Air Force Handbook will enable the Air Force to host it in the same location as other 15-series publications, allow for more frequent updates, and will ensure appropriate review and approval of the processes and procedures contained in the document. The handbook, when used with relevant data and additional Air Force guidance, provides general guidance for effective meteorological techniques for a variety of parameters. It is not a substitute for sound judgement and situationally relevant meteorological reasoning. Why buy a book you can download? We print the book so you don’t have to.
