Scientists use this product to quickly estimate the most intense convection and higher echo tops, as an aid to identify storm structure features, and for pilot briefing purposes. This product generates a color coded image that shows the height of an echo top. This product is used as an effective hail indicator, to locate most significant storms, and to identify areas of heavy rainfall. The water content of a 2.2 x 2.2 nm column of air, which is color-coded and plotted on a 48-nm map. This product is used to reveal the highest reflectivities in all echoes, examine storm structure features, and determine intensity of storms. Composite Reflectivity (NCR/37)Ī display of maximum reflectivity for the total volume within the range of the radar. When the FAA updated TDWR between January 2017 and May 2019, the elevation angle of this product became the same as the lowest elevation Reflectivity product (TR0 or TZ0). Long Range Digital Base Reflectivity (TZL/186)ĭigital Reflectivity data are measured at an elevation angle of 0.6 degrees with a maximum range of 225 nm. Data for the three lowest elevation angles are available, with a maximum range of 48 nm. These products are used to estimate wind speed and direction, locate boundaries, locate severe weather signatures, and identify suspected areas of turbulence. Cool colors (green) represent negative values and warm colors (red) represent positive values. Digital Base Velocity (TV0, TV1, TV2/182)Ī measure of the radial component of the wind either toward (negative values) or away from (positive values) the radar. The three lowest elevation angles are available with a maximum range of 48 nautical miles (nm). These products are used to detect precipitation, evaluate storm structure, locate boundaries, and determine hail potential. Digital Base Reflectivity (TR0, TR1, TR2/181 or after TZ0, TZ1, TZ2/180)Ī display of echo intensity measured in dBZ.

During severe weather situations, reflectivity signatures can provide valuable clues as to what threats to expect from a particular cell.General products include Base Reflectivity and Base Velocity as well as graphical products derived from algorithms including Spectrum Width, Vertically Integrated Liquid, and the Velocity Azimuth Display (VAD) Wind Profile.

Bright reflectivity returns that are stationary and appear during both calm and inclement weather are usually land-based obstructions such as mountains, trees, or especially wind farms (nothing gets electromagnetic signals confused like spinning metal blades!).

This is helpful for picking out snow/mix/rain transition zones In all snow situations, dBZ values of 40 indicate 3-4”/hr snowfall rates and whiteout conditions. Anything larger than this is usually due to “bright banding” where the radar is seeing the part of the atmosphere where snowflakes are clumping together and melting into raindrops.

In cold climates during the winter months, actual dBZ values rarely exceed 40.

This is your standard radar data that shows precip or other solid/liquid particles in the atmosphere. The first type of data currently available is reflectivity. We currently have two types of radar data available with plans to add more soon. Use radar data with caution especially if your area of interest is far from the nearest radar location! A lot can happen between 0 and 5,000 feet and therefore the depiction of precipitation given by radar may differ some from what’s actually happening on the ground. Because of this phenomenon, the radar beam will only see precipitation falling through the mid levels of the atmosphere. To see this in action, imagine a circle (earth) with a straight line emanating from some point on the circle if you continue this line out into space, it will gradually get farther and farther from the circle. Because the earth is round and the radar beam is flat, the farther away from the radar tower the beam (energy) travels, the farther removed from the ground becomes. There is a notable constraint to radar data though. This is the highest resolution radar data available which enables you to see features such as sea breeze or outflow boundaries that standard resolution radar entirely misses. This data is gathered from over a hundred radar towers located across the US.
