These scans are interpreted by a computer and translated into an image. A complete set of scans takes around 5 minutes to complete. Doppler radars scan the horizon in 360˚ degrees in a set pattern of angles from very low (along the horizon) to very high (almost straight up). This process of emitting a signal, listening for any returned signal, then emitting the next signal, takes place very fast, up to around 1300 times each second. It measures the speed of vehicles by detecting the. The radar gun is a Doppler radar unit that can be static, vehicle-mounted or hand-held. Brown in 1954, the radar gun is often used in law-enforcement purposes to calculate the speed of moving vehicles. Computers analyze the strength of the returned pulse, the time it took to travel to the object and back, and the phase shift of the pulse. A radar gun is a device for measuring the speed of moving objects. The radar instrument receives a signal from this reflected energy during its listening period. A small fraction of the scattered energy is directed back toward the radar. If the energy strikes an object (raindrop, snowflake, bug, bird, etc), the energy is scattered in all directions. The radar emits a burst, or pulse, of energy.

The furthest right column is the KP Index, and scan for numerous days in a row of 4 or above. NEXRAD (Next Generation Radar) stations obtain weather information (precipitation and wind) based upon returned energy. The NOAA website has an extended 27 day forecast that can help with longer range planning. location of the click, with description HTML from its properties. When a click event occurs on a feature in the states layer, open a popup at the "source-layer": "service_areas_dissolved-0ph7cn" , Climate Prediction Center 5830 University Research.

"source-layer": "Weather_Radar_Stations-14wxnv" , A probabilistic strength forecast is available here.This process can be repeated for the warning polygons ( ) and all other layers on the RIDGE pages ( ) Load the image into a GIS as any other layer. (The "_0" in the file name indicates that this is the latest image.) Save both the image of the radar (file ending in ".gif") and the world file (ending in ".gfw") that goes with it to a computer in the same directory. Go to the directory where the radar images reside: Go to the page that generates KML/KMZ files for your application that uses KML/KMZ. Load RIDGE Radar images and NWS warning polygons using KML/KMZ. If the image file name has a 3-character extension (image1.gif), the world file has the same name followed by an extension containing the first and last letters of the image's extension and ending with a 'w' (image1.gfw). Line 6: y-coordinate of center of upper left pixel Line 5: x-coordinate of center of upper left pixel Line 4: NEGATIVE of y-dimension of a pixel in map units

Features of this site include: sectoring, animation of. Line 1: x-dimension of a pixel in map units Interactively zoom and animate weather satellite images from a variety of geostationary satellites. A world file is an ASCII text file associated with an image and contains the following lines:

With GIS software (free or off-shelf) you can import the image and add any overlaying dataset without the distraction of unwanted layers.Įach of the RIDGE radar image has a "world file" associated with it. Each RIDGE radar image is created separately without backgrounds on the image and in a standard geographic projection referenced to North American Datum 1983 (NAD83). The best feature about the RIDGE enhanced views of NWS Doppler radar images is that each image can be incorporated into GIS software.
