- Nota adicional1
- AWOS stations provide a minute-by-minute update of weather parameters such as wind speed and direction, temperature and dew point, visibility, cloud heights and types, precipitation, and barometric pressure. A variety of AWOS system types are available (from AWOS 1 to AWOS 3), each of which includes a different sensor array.
- Contexto
- Goal: To identify the types and contents of surface observations, as well as the units, terms, and equipment used, including the requirements for routine and special aviation observations; regional and global observation networks; the elements of surface observations (wind direction, wind speed, visibility, runway visual range (RVR), present weather, cloud, air temperature, dew-point temperature, pressure, and supplementary information); differences filed by States; Automated Weather Observing Systems (AWOS), including their current limitations and related issues; synoptic stations, including land and maritime stations; and ground-based radar observations.
- Automatic weather stations may be designed as an integrated concept of various measuring devices in combination with the data acquisition and processing unit. Such a combined system of instruments, interfaces and processing and transmission unit is usually called an automated weather observing system (AWOS) or automated surface observing system (ASOS). It has become common practice to refer to such a system as AWS, although it is not a ‘station’ fully in line with the stated definition. Nevertheless, throughout this chapter, an AWS may refer to just such a system.
