Weather Spark is a new site that offers weather data from more than 4,000 weather stations around the world. Not only is there data from more than 4,000 stations, there is also data going back more than fifty years. All of this data can be used to create comparisons of current weather conditions around the world, comparisons of current and past weather conditions, and to view global climate trends.

Applications for Education
Weather Spark could be a great resource for anyone teaching lessons on meteorology. Students can work on recognizing patterns by creating charts of historical weather data. You could also have students create and investigate questions based on the data available. For example, have them try to figure out why Mumbai, India has a temperature pattern that dips in the summer.
