For more information about GOES-17's cooling issue, view NOAA's Summary of the GOES-17 Cooling System Issue. This issue isn't something we, nor anyone, can resolve as the problem comes from the satellite itself. Long story short - there is a daily and seasonal impact to the quality of data for a subset of the satellites ABI bands. GOES-17 (currently GOES-West) unfortunately has a problem with it's cooling system. What's the issue with GOES-West data for some products?
LOCAL CLOUD HEIGHT MAP NWS SERIES
Here are a few links you may find useful:Īnd in general, the site is loaded with information and has many resources that help explain the GOES-R series of satellites. Where can I learn more about the ABI bands? An SPC moderate or high risk will typically take priority over most other things. This allows flexibility to have rapid updates for severe weather, fire weather, hurricanes and other events or occurrences.
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. Who determines where the mesoscale regions are?
LOCAL CLOUD HEIGHT MAP NWS UPDATE
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. The satellite’s ABI will scan each of these regions once per minute, or it can scan one region every 30 seconds.
LOCAL CLOUD HEIGHT MAP NWS FULL
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. This page, its features and contents are largely in a completed state.
