Integration of Aviation AWOS with RWIS

The Integration of Aviation AWOS with RWIS application is an easy-to-use web-based tool for users from California’s airports and heliports, particularly those used for EMS. It provides them with localized and timely weather condition and forecast information. As a prototype, the application provides stakeholders with an initial design of a web platform that can be reviewed and critiqued. Based on this review and critique, changes, enhancements and so forth will be incorporated during future project phases.

UPDATE: Monday, February 8th, 2016

Phase II of the Integration of Aviation AWOS with RWIS project was recently completed. The project focused on the development of a prototype system that integrates weather data from aviation Automated Weather Observing Systems (AWOS) and Automated Surface Observing Systems (ASOS) and surface transportation Roadside Weather Information System (RWIS), as well as surface and aloft weather forecasts alerts and warnings, satellite and radar imagery, roadside cameras and more. In addition to system development, the project team conducted a business case analysis, researched additional sources of relevant data, documented detailed system requirements, analyzed gaps in existing weather station coverage, and used three separate mechanisms to evaluate the system.

A final report presentation was delivered in conjunction with the Caltrans October Research Connection Event. See the December 3rd, 2015, project update for more details.

The Integration of Aviation Automated Weather Observation Systems (AWOS) with Roadside Weather Information Systems (RWIS), Phase II, Final Report can be downloaded here, from the AWOS/RWIS Project's Documents page, and from the Documents archive.

The following figures from the final report help to illustrate the project results:

This heat map shows airport locations relative to estimated coverage for weather stations in the Aviation WeatherShare System (AWOS, ASOS, RWIS, MADIS, MesoWest). Blue indicates coverage and red indicates gaps (lack of coverage).

Airports Relative to Heat Map for Coverage from Reporting AWOS / ASOS / RWIS / MADIS / MesoWest Site with QC-Passed Observations and Reporting Frequency of 15 Minutes or Better (Blue = less than 25 miles from nearest site, White = 25 miles from nearest site, Red = more than 25 miles to nearest site).

The Wind Aloft layer shows the direction and magnitude of forecast wind at various altitudes in an easy to interpret, visual display.

Wind Aloft Layer 6000 ft. AMSL.

Caltrans CCTV camera images play a prominent role in the system. These roadway images provide relevant information about visibility, snow, rain, etc. A picture is worth a thousand words!
