Tucson doppler radar loop update#

Hail is a good reflector of energy and will return very high dBZ values. These values are estimates of the rainfall per hour, updated each volume scan, with rainfall accumulated over time. Depending on the type of weather occurring and the area of the U.S., forecasters use a set of rainrates which are associated to the dBZ values. The higher the dBZ, the stronger the rainrate.

Typically, light rain is occurring when the dBZ value reaches 20. The scale of dBZ values is also related to the intensity of rainfall. Disclaimer Information Quality Help Glossary. KEMX Tucson, Arizona Based Nexrad Doppler Radar Station with Enhanced Nexrad Doppler Radar from the National Weather Service for the General Tucson, AZ. The value of the dBZ depends upon the mode the radar is in at the time the image was created. US Dept of Commerce National Oceanic and Atmospheric Administration National Weather Service National Level II NWS Radar Operation Center 1200 Westheimer Drive Norman, OK 73069 Comments Questions Please Contact Us. The NOWRAD Radar Summary maps are meant to help you track storms more quickly and accurately. Notice the color on each scale remains the same in both operational modes, only the values change. The Current Radar map shows areas of current precipitation. The other scale (near left) represents dBZ values when the radar is in precipitation mode (dBZ values from 5 to 75). One scale (far left) represents dBZ values when the radar is in clear air mode (dBZ values from -28 to +28). Sun Shuttle to hold meetings on proposed route changes. Each reflectivity image you see includes one of two color scales. DPS: Motorcyclist caught driving 150mph in Casa Grande. Data collected using Doppler radar polarimeteric technology are objectively analyzed by complex precipitation. 3-Day Infrared Satellite Loop 3-Day Water Vapor Loop (Color) Regional Satellite Loops. High resolution and interactive rainfall data on Google Maps. The radar products are also available as OGC compliant services to use in your application. Radar-estimated precipitation accumulation for the past 24 hours to 3 days. The dBZ values increase as the strength of the signal returned to the radar increases. The NWS Radar site displays the radar on a map along with forecast and alerts. So, a more convenient number for calculations and comparison, a decibel (or logarithmic) scale (dBZ), is used. See the latest Arizona Doppler radar weather map including areas of rain, snow and ice.

Reflectivity (designated by the letter Z) covers a wide range of signals (from very weak to very strong). 'Reflectivity' is the amount of transmitted power returned to the radar receiver. 2 Today Hourly 10 Day Radar Season Davis-Monthan AFB, AZ Radar Map Rain Frz Rain Mix Snow Davis-Monthan AFB, AZ Expect dry conditions for the next 6 hours. Please consult your device documentation for instructions.The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan.
