Level II is the radar data after a small amount of initial processing. With the advent of dual polarization beginning in 2011, additional base products of differential reflectivity, correlation coefficient and differential phase are available. You can find more information on how radar data is encoded at NOAA. Doppler radars detect atmospheric precipitation and winds, which allow scientists to track and anticipate weather events, such as rain, ice pellets, snow, hail, and tornadoes, as well as some non-weather objects like birds and insects. |61|NTV|Tornadic Vortex Signature| The Sachidananda-Zrnic Algorithm reduces range ambiguity for Doppler data. 716 Farm House Ln > > > So in a nutshell > > FNEXRAD > > and > > NNEXRAD ( and a list of sites, or do you want ALL of them) > > Thoughts.. > > > Jeff > ----- > Jeff Weber address . > > > > > 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. 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. The NEXRAD Level II real-time data is hosted in the unidata-nexrad-level2-chunks Amazon S3 bucket in the us-east-1 AWS Region. Overlay products for Level 3 are alphanumeric data that give detailed information on certain parameters for an identified storm cell. The IEM receives a feed of NEXRAD Level III products from the Unidata Internet Data Distribution. Available products are listed below. |ID|Product Code(s)|Description| # Differs from IEEE 768-2008 format so np.float16 cannot be used.

A locked padlock These VCPs have the same elevation angles as VCPs 11, 12, and 21 respectively. Super resolution makes a compromise of slightly decreased noise reduction for a large gain in resolution.

In-flight icing and hail detection algorithms have enhanced overall data quality in present-day NEXRAD. Data coverage varies by station and ranges from May 1992 to 1 day from present. NEXRAD Level 3 products are used to remotely detect atmospheric features, such as precipitation, precipitation-type, storms, turbulence and wind, for operational forecasting and data research analysis. These checks include: The parser will also return rich error where possible indicating that a specific product or packet type is not supported. Summarizing: The software change is typically modifying the polling address. Level 2 data can be considered raw data from the radar and provides the "Reflectivity" products that you're used to seeing on web sites and the local news.
