In most cases, electronic downloads of the data are free, however fees may apply for data certifications, copies of analog materials, and data distribution on physical media. The work in this project is based mainly on the document 2620001 ICD FOR THE RPG TO CLASS 1 USER - Build 19.0. 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. The NEXRAD system detects precipitation and wind, and its data can be processed to map precipitation patterns and movement. I'm open to requests or pull requests that add additional parsing algorithms. Nexrad radar sites provide data in two formats: Level 2 and Level 3.

These checks include: The parser will also return rich error where possible indicating that a specific product or packet type is not supported. Level 1 is used internally by the system and converted to Level 2 which is made available to end users. In 2010, the deployment of the Dual Polarization (Dual Pol) capability to NEXRAD sites began with the first operational Dual Pol radar in May 2011. It also provides velocity data and several more advanced data outputs. NEXRAD Level 3 products were collected by the NOAA National Weather Service (NWS) and are archived at the NOAA National Climatic Data Center (NCDC). Secure .gov websites use HTTPSA The radar system operates in two basic modes: a slow-scanning Clear Air Mode (Mode B) for analyzing air movements when there is little or no precipitation activity in the area, and a Precipitation Mode (Mode A) with a faster scan for tracking active weather.

An example of plotting data produced from this library can be found in nexrad-level-3-plot. It will plot raster data created by the package mentioned above but there are several limitations that will be addressed in future releases. A successful test will generate several .json files in the ./output folder. Scientists use these products to estimate wind speed and direction, locate boundaries, locate severe weather signatures, and identify suspected areas of turbulence.

However, denser vertical sampling at lower elevation angles provides better vertical definition of storms, improves the detection capability of radars impacted by terrain blockage for better rainfall and snowfall estimates, results in the identification of more storms, and provides quicker updates.
