NexradNow

About NexradNow Android App

This app downloads a Nexrad weather product for your local area and displays it on your Android device. Currently, it uses the GPS location of your device to find several nearby Nexrad radar stations, downloads recent weather products directly from the NWS radar operations center, and displays them on your device. A simple state map overlay is generated as a visual reference.

The display is intended to show the products for a broad geographic area (several states), rather than for a single very local area. It aggregates the data from the various Nexrad stations to achieve this coverage. It can search for Nexrad stations within up to 500 miles of your current location.

The products currently supported include the base & composite reflectivities at 120 and 240 nm ranges.

You can choose your location from either the device's current GPS location, or you can center on an existing Nexrad site. If you are feeling adventurous, you can enter a city/state or place name, and the app will use Android's geocoder to figure out a physical location.


The app continues to evolve - it originally served as a learning exercise for me, but I intend to add features as time permits. Some of the features on the to-do list include:

* animation of weather products when possible

Your suggestions welcome - or even better, check out the code on github!

When you first launch the application, it will prompt you for an email address. This is used as a password for "anonymous" FTP into the Nexrad servers, so that the radar operations center has some minimal record of who is downloading their products. It is not shared with anyone else.
