We have released a new version of our Dual-Pol NEXRAD page. This new version no longer uses Flash, but instead uses a new in-house animator for both desktop and mobile devices. Additionally, the mobile version is designed to act as a "Web-App" on all mobile devices. Instructions are available on the page when loaded with on an applicable device. View Page To aid in mitigating the cooling issue onboard GOES-West, NOAA is adjusting the scanning strategy of the satellite between 6Z-12Z each night around the time of the equinoxes.Changes & impacts include Full-Disk scans every 15 minutes (instead of every 10), only one mesoscale sector per minute (instead of two), andduring this time. This will result in a loss of some GOES-17 imagery on our site, particularly over the western US.We are investigating our options to compensate for the loss of imagery during this time, but due to technical and logistical challenges we may not be able to implement a workaround anytime soon.More information on the GOES-17 cooling issue, impacts to products, the adjusted scanning strategy and other details can be found here For further information, check the following twitter accounts for periodic updates on product generation status and website improvements; @CoDWXData and @CODMeteorology . Your feedback is always appreciated, so feel free to respond to tweets or send us an email using our Feedback page.

GOES-R Series Satellite FAQ:

What are ABI bands?

Which bands are closest to what I’m used to?

What ABI bands should I use?

How often to these products update?

What are the mesoscale regions?

Who determines where the mesoscale regions are?

Where can I learn more about the ABI bands?

What's the issue with GOES-West data for some products?

I think I found a problem with your page or imagery, how can I tell you about it?

This page, its features and contents are largely in a completed state. However, active development is still on going. 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 . The overwhelming majority of the imagery on this page is rendered at a resolution of 1600x900 pixels. Because of this we recommend viewing this page at a 16:9 or 16:10 aspect ratio at a resolution of 1920x1080 or greater. A mobile version of this page is still in development.The Advanced Baseline Imager (or ABI for short) is one of the instruments on the GOES-R series of satellites. There are 16 ABI bands that each sample a specific region of the light spectrum. They include two visible bands, four near-infrared bands, and ten infrared bands.Compared to the previous generation of GOES satellites, ABI 02, or the Visible Red band, samples the same wavelength as legacy visible products. ABI 09, the Mid-Level Water Vapor band, is most like the legacy water vapor band. And ABI 14, the Longwave Infrared Window band, is the closest to the legacy LW-IR bandThe best answer to this question is really all of them, as they all have their uses. But some bands do have some interesting characteristics. ABI 02 has the highest spatial resolution of all the ABI bands at 500 meters (visible was previously 1km). ABI 07 senses the widest range of temperatures, and among other things is very useful for fire detection. And band 13 often produces cleaner looking images than its more traditional counterpart, band 14. But please use them all, and explore for yourself each band’s strengths and weaknesses.Imagery from the mesoscale regions will update every minute. Occasionally, the two mesoscale regions can be overlapped to produce 30 second imagery. CONUS imagery, which is what the bulk of our sectors use, updates once every five minutes. 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.Both GOES-East and GOES-West are capable of having up to two mesoscale scanning regions. The satellite’s ABI will scan each of these regions once per minute, or it can scan one region every 30 seconds. This results in satellite imagery that can update faster than most weather radars! Beyond that, there is no difference in the products themselves between mesoscale imagery and CONUS imagery.Not us, though that would be nice. Actually, any National Weather Service (NWS) office or National Center (such as SPC or NHC) can request a mesoscale domain be positioned to sample a specific region or feature of interest. This allows flexibility to have rapid updates for severe weather, fire weather, hurricanes and other events or occurrences. An SPC moderate or high risk will typically take priority over most other things.Here are a few links you may find useful:And in general, the goes-r.gov site is loaded with information and has many resources that help explain the GOES-R series of satellites.GOES-17 (currently GOES-West) unfortunately has a problem with it's cooling system. Long story short - there is a daily and seasonal impact to the quality of data for a subset of the satellites ABI bands. This issue isn't something we, nor anyone, can resolve as the problem comes from the satellite itself.
