An interface for the AWS NEXRAD Level-II archive as well as other meteorological archive data sources.

• AWS NEXRAD Level-II Archive: Fully Functional
• Iowa State Watch, Warning, and Advisory Archive: Partially Implemented
• AWS GOES 16/17/18 Archive: Planned
• SPC Case Archive: Planned

This library does not return ready-for-use radar data objects to the developer. Rather, it returns a list of the request files in the AWS S3 bucket as well as the links that can be used to programmatically download them. If you need a library to read the NEXRAD files, NetCDF Java supports NEXRAD's format, Message 31.

This library does return warning polygons as ready-to-use objects.

Not all WWA types have been supported yet. Returned archived warnings may contain null values in the warningType variable due to this. Implementing all the rest of the WWA types is my current first priority with this project.

The amount of dependencies required to build this project from source is quite large. I plan to write out a list of links to the required JAR files as well as an optional Maven pom.xml file. Until I get that done, here's a screenshot of my project folder.
