The WSDDM system provides the airport operations community with PC based workstations showing current data from local RADARS and weather stations. Data is updated automatically. The display windows are tailored to provide weather information specifically for the airport operations personnel in a concise and easy to understand format. Users can choose from 5 NEXRADs in the region as well as select preset zoom states or one of their own choosing.
Users can click anywhere on the RADAR image and get the closest 23 METAR reports, decoded into tabular form in the upper right corner window on the display. (This screen shot was intentionally created smaller than the actual one for the WWW, and the window shows only the nearest four). Click on a metar for a demonstration of how it works.

On the left side of the screen is a plan view image of the LaGuardia region with storm motion and area METAR stations plotted over the top. The yellow vectors are generated from an analysis of the OKX NEXRAD radar, located on Long Island, and the green vectors are generated from the DIX NEXRAD, located near Fort Dix. The tick marks on the vectors represent forecasted motion at 10 minute intervals.
The windows on the right edge of the screen provide quantitative information about the current conditions as well as a 30 minute forecast of expected precipitation. The LGA Selected Metars window displays the stations closest to an arbitrary point selected by clicking on the radar image. The window in the lower right corner displays two traces: a yellow radar reflectivity trace gathered from above a particular WSDDM snowgauge; and a pink trace depicting liquid equivalent precipitation accumulation. The dotted lines to the right of the red "now" line are forecasts.
