The Next Generation Weather Radar (NEXRAD) is a network of 160 high-resolution Doppler radar sites that detects precipitation and atmospheric movement and disseminates data in approximately 5 minute intervals from each site. import numpy as np import matplotlib.pyplot as plt from numpy import ma from metpy.cbook import get_test_data from metpy.io.nexrad import Level3File from metpy.plots import ctables % matplotlib inline. The bandwidth for this service would over-whelm the website, so it was moved to a new URL back in May 2012 . The address to this website was the same hostname as the main IEM website. Some easier to understand forms of this data include: Precipitation type, known as the Hydrometeor classification (Products N0H, N1H, N2H, N3H, packet code 165) Thanks much. 
Level II data are used for many purposes including: support of operations, maintenance
Estimates are based on reflectivity to rainfall rate (Z-R) relationships. Enter the email address you signed up with and we'll email you a reset link. The short answer is that the National Weather Service replaced the N?Q family of products (Digital Base Reflectivity) with "super-resolution" counterparts that have the identifier N?B, where ?

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. Why is China worried about population decline? A database of 82 radar stations and more than 1500 rain gauges in continental USA was compiled and used for the continuous downloading of radar images and rain data. An official website of the United States government Here's how you know. With NWS as the lead agency, the Tri-Agency partners use currently 160 NEXRAD systems. There are over 40 Level 3 products available from the NCDC. Please see the ./data and ./output folders. The products assist forecasters and others in weather analysis, forecasts, warnings and weather tracking.
