The Application of virtual globe software in fireweather forecasting
Tim Brice, NOAA/NWS, Santa Teresa, NM
For years, fire weather forecasters have relied on two dimensional topographic maps to try to understand how topography and weather combine to affect a fire. From the size and shape of a canyon that affects wind direction and speed, to the exposure of the burning slope which can affect temperature and humidity, knowing the topography can enable a forecaster to provide a more accurate forecast. Today, with the advent of virtual globe software, forecasters can better relate topography to weather and its effect on a fire. In addition to being able to visualize the topography, the availability of weather data in the Keyhole Markup Language format allows the forecaster to overlay temperature, humidity, wind and precipitation information on the terrain in the geobrowser to provide the best possible service. Moreover, after a large fire, mud slides and flash flooding are a big concern. Again, with the use of data in the Keyhole Markup Language format, forecasters can estimate overburn percentage and correlate that with both topography and with radar rainfall estimates. This paper will examine operational use of virtual globe software and Keyhole Markup Language formatted files to integrate meteorological and hydrological data in support of fire weather operations.
