RealEarth has that storm total composite too:
https://realearth.ssec.wisc.edu/?products=nexrstorm.90¢er=35,-94&zoom=4&basemap=bluemarble&labels=line&view=leaflet
That info link you post is a good explanation on the issues. You have to know when the totals are through. Some things in that U.S. composite might be a day's worth of rain. Some might be a week's worth of rain. You can get two sites next to each other that are very different because of that and then I guess somehow it is merged. If you looked at a site that tells you what it is through then you could determine if the storm totals for radar sites next to each other are through the same time period. Or about the same.
Then you have errors. For example, I assume that it hasn't rained just about constantly from October 10th through now in western Washington state.
https://radar.weather.gov/radar.php?rid=lgx&product=NTP&overlay=11101111&loop=no
That information is conveyed in the single site radar imagery at NOAA, in the top right above the image, as well as the Weather Underground in their NEXRAD display, if you select "Storm Total Surface Rainfall Accumulation" in the menu on their display:
https://www.wunderground.com/radar/us/wa/langley-hill/lgx
It also says it has rained as much as 192.6 inches in that time on the Weather Underground site. That could be a mistake on their site or a mistake of some other kind.
I don't know if you just need rain or if something like fog and smoke also count. I don't think that area would have seen continuous rain, but then again that is a very rainy area and you only need a little bit somewhere I believe.

Maybe they will post the beta version. It seems like NOAA does do that sometimes. Maybe rather often so you can give them feedback. When they updated the point forecast page I remember being able to view that early. Maybe for quite awhile actually.
But then again, April/May 2020 is not that long from now. You would think maybe we would have seen something already. I did a quick Google search and I didn't find anything. Maybe it is buried somewhere.
That display you had in your other post:
https://mrms.nssl.noaa.gov/qvs/product_viewer/
Is really good. The display itself isn't the most user friendly, but it has a lot of great data in it. You can loop the image and have up to 36 frames, changing the time between frames from 2 minutes to 1 hour. And you can access the last 7 days of data.
There's quite a bit that I don't know what it is.
It would be nice if you could select a single radar site and then get velocity data too for it. And I guess the new NOAA display will allow you to save. You can save a link to your view in this one, but it's nice to be able to save to the image if you wanted to share it to social media for example.
I don't know, maybe they will keep some of what they have now too, such as the lite imagery they have now. But they do say "NWS will replace the existing site and features with the following" omn that page here:
https://www.weather.gov/hgx/radarquestions
So that seems like they might not have the other parts of the site around any longer. |
