We are really happy when public safety agencies use the imagery from http:\/\/ondemand.nssl.noaa.gov\/ to show the impact of the recent tornadoes<\/a> in Illinois.\u00a0 Hey, that’s our stuff, we want to shout. It reminds us of why we do what we do.<\/p>\n

But there’s a lot of noise on those accumulation products, noise that can be removed by the use of Multiple Hypothesis Tracking (MHT).\u00a0 We couldn’t do MHT on-demand or in real-time because it is so slow, but just a few weeks ago, we figured out a way<\/a> to do it faster with not much of a tradeoff in noise removal.<\/p>\n

We repeated the analysis of the Illinois outbreak using the faster method and boy, is it faster! We can process an hour of data in 5 minutes!\u00a0 (Here are the cleaned-up rotation tracks for the Illinois tornadoes<\/a>. It is a KML file, so view it in Google Earth.) MHT will be implemented on the ondemand website in a few days.\u00a0 So, the next time you see folks sharing Rotation Tracks images, they will be cleaner and crisper.<\/p>\n
