By the week of April 1st, 2019 Full Disk imagery will update every 10 minutes, but it’s possible to have 5 minute updates if the mesoscale regions are turned off.īoth GOES-East and GOES-West are capable of having up to two mesoscale scanning regions. CONUS imagery, which is what the bulk of our sectors use, updates once every five minutes.

Occasionally, the two mesoscale regions can be overlapped to produce 30 second imagery. Imagery from the mesoscale regions will update every minute. But please use them all, and explore for yourself each band’s strengths and weaknesses. And band 13 often produces cleaner looking images than its more traditional counterpart, band 14. ABI 07 senses the widest range of temperatures, and among other things is very useful for fire detection. ABI 02 has the highest spatial resolution of all the ABI bands at 500 meters (visible was previously 1km).

But some bands do have some interesting characteristics. The best answer to this question is really all of them, as they all have their uses. And ABI 14, the Longwave Infrared Window band, is the closest to the legacy LW-IR band ABI 09, the Mid-Level Water Vapor band, is most like the legacy water vapor band. Which bands are closest to what I’m used to?Ĭompared to the previous generation of GOES satellites, ABI 02, or the Visible Red band, samples the same wavelength as legacy visible products. They include two visible bands, four near-infrared bands, and ten infrared bands. There are 16 ABI bands that each sample a specific region of the light spectrum.

The Advanced Baseline Imager (or ABI for short) is one of the instruments on the GOES-R series of satellites.

GOES-R Series Satellite FAQ: What are ABI bands? A mobile version of this page is still in development. Because of this we recommend viewing this page at a 16:9 or 16:10 aspect ratio at a resolution of 1920x1080 or greater. The overwhelming majority of the imagery on this page is rendered at a resolution of 1600x900 pixels. If you are curious about feature development and want to float an idea past our development staff, we are certainly open to suggestions from our users. However, active development is still on going. Since hail can cause the rainfall estimates to be higher than what is actually occurring, steps are taken to prevent these high dBZ values from being converted to rainfall.This page, its features and contents are largely in a completed state. 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. The value of the dBZ depends upon the mode the radar is in at the time the image was created. Notice the color on each scale remains the same in both operational modes, only the values change. 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). Each reflectivity image you see includes one of two color scales. The dBZ values increase as the strength of the signal returned to the radar increases. So, a more convenient number for calculations and comparison, a decibel (or logarithmic) scale (dBZ), is used. 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. The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan.
