It also provides velocity data and several more advanced data outputs. 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. Sent from my Nexus 6 using Stormtrack mobile app Jeff Duda EF6+, PhD Staff member Department of Agronomy on synchronization, calibration, date, time, antenna position, Nyquist velocity, and operational mode). The work in this project is based mainly on the document 2620001 ICD FOR THE RPG TO CLASS 1 USER - Build 19.0.

The lower Level 2 data are base products at original resolution. The products assist forecasters and others in weather analysis, forecasts, warnings and weather tracking. 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. Level codes 0 and 1 correspond to 'Below Threshold' and 'Range Folded', respectively, while level codes 2 through 255 correspond to the reflectivity data itself".

A test script is provided and will generate .json output from all of the files in the ./data and ./data-error folder. The recommended practice is to test that your desired data structure exists in the returned object before doing any further processing with it. From these Level 2 data, computer processors generate numerous meteorological analysis Level 3 products based on the Level 3 product algorithms. This dataset consists of Level 3 weather radar products collected from Next-Generation Radar (NEXRAD) stations located in the contiguous United States, Alaska, Hawaii, U.S. territories and at military base sites. Scientists use these products to estimate wind speed and direction, locate boundaries, locate severe weather signatures, and identify suspected areas of turbulence.
