WeatherData vs WeatherComp Usage & Stats

WeatherData is built for meteorologists and weather enthusiasts who wish to view real-time data plots of North American surface weather observations. The app retrieves data from the National Oceanic and Atmospheric Administration (NOAA) public web feeds that include surface data from U.S. and Canadian airports. Data from the National Data Buoy Center are also included for access to weather data from offshore weather buoys and special coastal stations. Data plotted include current temperature, dew point, pressure, wind, sky cover, and precipitation. Data plotted are limited to the most recent observation within the last two hours.
