The Sachidananda-Zrnic Algorithm reduces range ambiguity for Doppler data. Values between 0. This product plots wind barbs on a height staff in 1,ft. Digital data is available for free, and paper copies can be purchased and certified. Specific elevation angles depend on the site and scanning mode of the Radar. Scientists use this product to locate flood potential over urban or rural areas, estimate total basin runoff, and provide rainfall data 24 hours a day. Radar Messages. A product designed to locate storms that have the potential to produce hail. Storm total precipitation accumulation is available on a 1. A measure of velocity dispersion within the radar sample volume.

Scientists label hail potential as either probable hollow green triangle or positive filled green triangle. This product's primary use is to estimate turbulence associated with mesocyclones and boundaries. Follow us on Twitter. Hydrometeor Classification is a computer algorithm output that tries to classify targets in the radar volume. The current far right and up to 10 previous plots may be displayed simultaneously. Climate and Past Weather. Meteorological targets with complex shapes, or with a large degree of variety, will generally have values between 0. Product Descriptions. Additional categories include dual-polarization base data of differential reflectivity, correlation coefficient, and differential phase. Differential Reflectivity values are measurements related to the returned energy difference between the vertically and horizontally polarized radar pulses. The official Interface Control Documents ICDs contain detailed information on the binary data formats and product specifications. The VCP 31 long pulse provides a better signal-to-noise ratio, permitting lower reflectivity returns to be detected, while VCP 32 short pulse provides a higher unambiguous velocity. This product is generated for each elevation angle that the radar scans and can be particularly useful for tracking icing conditions above the surface. Severe Thunderstorms.
