You can find more information on how radar data is encoded at NOAA. According to the ICD for the Product Specification , "the 256 data levels of the digital product cover a range of reflectivity between -32.0 to +94.5 dBZ, in increments of 0.5 dBZ.

The lower Level 2 data are base products at original resolution. Level II is the radar data after a small amount of initial processing. During 2008, the WSR-88D radars were upgraded to produce increased spatial resolution data, called Super Resolution. The parser will read files as either a string or a buffer. The two modes employ nine Volume Coverage Patterns (VCPs) to adequately sample the atmosphere based on weather conditions. |0x0013|Special Graphic Symbol Packet| The output also includes status information required to properly interpret the data (e.g., information on synchronization, calibration, date, time, antenna position, Nyquist velocity, and operational mode).

Errors will be logged to the console for the data which has intentional errors, but the data that can be parsed will still be returned from each file. Possible by Unidata. To start, you can subscribe to these notifications using Amazon SQS and AWS Lambda. Part A - System Concepts, Responsibilities, Part B - Doppler Radar Theory and Meteorology. I suspect you would want the level III data as it more accurately delivers what I think you want ( 1 & 3 hour storm totals, and storm total precip) and also the floater FNEXRAD to get the 1 Km mosaic of base reflectivity. Over the past decades, rapid developments in digital and sensing technologies, such as the Cloud, Web and Internet of Things, have dramatically changed the way we live and work.
