New way to look at ASCAT data
We just figured out a neat trick way to display the ASCAT data, which we have set up for the tropical Atlantic in support of the OAR NW rowing team.
The trick takes advantage of the fact that there are now two ASCAT satellites, Metop-A and Metop-B which circle the earth over the same ground track, but just 47 minutes apart. Thus we can show them side by side, and if we assume not too much has happened to the winds in 47m, we get a nice broad swath of data across the ocean, from where the boat is now (24N, 63W) all the way to Miami.
The pictures below should up date and be live, so keep in mind there might not have been a satellite pass when you are looking, in which case, check back in a couple hours.
