- Contexto
- 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.
