In 1996, Nav Canada specified the requirements for automated aviation observations from approximately 50 sites, not including the DND AWOS network. Also, several software components of the AWOS are being upgraded in an effort to improve the product to the end-user. This guide discusses the state of the AWOS assuming these upgrades are in place. This manual is intended to provide guidance information to all users of AWOS data. This manual is divided into Chapters, Sections and Sub-Sections.
Chapters are groupings of information pertaining to the same subject areas.
Sections provide a smaller grouping, and Subsections and headings in the text help the user find more specific information. A number of tables and figures incorporated within a Chapter are concise presentations of information needed within the Chapter. Those presented in Appendices provide additional detailed information. Interpretation of Terms - 'Output', 'Code', 'Message' and 'Report' 'Output' refers to the product generated by an automated system or sensor.
