Automated Surface Observing System. Site Technical Manual S100


Book Description

The Automated Surface Observing System (ASOS) automatically collects weather data and provides accurate, 24-hour accumulated weather reports to local weather observers; weather forecasters; airport personnel, including pilots and air traffic controllers (ATC's); and Federal Aviation Administration (FAA) and National Weather Service (NWS) personnel. ASOS functions include: measurement of weather elements, data processing and display, communication, and data storage (archiving). The ASOS is a flexible system with a modular construction that allows deployment in a variety of configurations for operation with or without the attendance of an observer. Unattended, the ASOS automatically collects, process, and error checks data and formats, displays, archives, and reports the weather elements included in a surface weather observation. The ASOS also accepts imputs from observers (when present), who may also override or add information to the automatically generated observation. Because of the flexibility of the ASOS, it can provide useful weather information in text, video, and audio format to a variety of users. Table 1.1.1 lists the users with which the ASOS can interface.




The National Weather Service Modernization and Associated Restructuring


Book Description

The Modernization and Associated Restructuring (MAR) of the National Weather Service (NWS) was a large and complex re-engineering of a federal agency. The process lasted a decade and cost an estimated $4.5 billion. The result was greater integration of science into weather service activities and improved outreach and coordination with users of weather information. The MAR created a new, modernized NWS, and, significantly, it created a framework that will allow the NWS to keep up with technological changes in a more evolutionary manner. The MAR was both necessary and generally well executed. However, it required revolutionary, often difficult, changes. The procurement of large, complex technical systems presented challenges in and of itself. The MAR also affected the career paths and personal lives of a large portion of the field office workforce. The MAR created a new, modernized NWS, and, significantly, it created a framework that will allow the NWS to keep up with technological changes in a more evolutionary manner. The National Weather Service Modernization and Associated Restructuring presents the first comprehensive assessment of the execution of the MAR and its impact on the provision of weather services in the United States. This report provides an assessment that addresses the past modernization as well as lessons learned to support future improvements to NWS capabilities.




A Short-term Evaluation of the Automated Surface Observing System at Cleveland, Ohio


Book Description

"The National Weather Service Forecast Office (NWSFO) in Cleveland (CLE), Ohio has been performing a study of the NWSFO CLE Automated Surface Observing System (ASOS). This study was performed in conjunction with precommissioning activities for the NWSFO CLE ASOS. After the performance of the NWSFO CLE ASOS is judged consistent with the standards set by the ASOS Transition and Implementation Branch (ATIB) of the National Weather Service (NWS), as found in the ASOS Site Component Commissioning Plan (National Weather Service 1993), it will be commissioned and become the primary reported of surface weather observations at NWSFO CLE"--Introduction.
