Mapping Water Vapor for More Accurate Weather Predictions
Image credit: Mike-wise/FlickrThe same thing that limits the accuracy of your GPS unit to within a few meters also prevents meteorologists from making precise weather predictions. Atmospheric water vapor interferes with radio signals as they are sent from GPS satellites and this same vapor scrambles weather radar, making certain things like storm predictions very difficult.One researcher believes that by creating a map of atmospheric water vapor, some of this interference could be accounted for, leading to much more accurate weather for...Read the full story on TreeHugger
