Experts whose specialty is to interpret the data monitor the National Weather Service radars. They then publish some of their images and findings on their website and in other media, such as radio and television. All these avenues serve to help us understand the weather conditions and patterns in our own backyards.

The National Weather Service radars use NEXROD, or Next Generation Radar technology and Doppler radars. There are generally four types of data and images that are produced from these radars. They are base reflectivity, composite reflectivity, one-hour total rainfall and storm total rainfall. All these images make up the full picture of storm and weather predictions.

National Weather Service Radars are located in each state except all the New England states that are small and can be serviced by the same handful of radars. There is also one above Puerto Rico and one above Guam. Some areas have a higher concentration of National Weather Service Radars than others, which probably has to do with the conditions of a given area. Such a large occurrence of radars allows for more accurate readings.
