Incoherent scatter radars observing the eclipse
There are two incoherent scatter radars, which will be able to directly observe the ionospheric effects of the eclipse. The Millstone Hill Radar in Boston, and the Arecibo Radar in Puerto Rico. Both of these instruments will be running during the eclipse. They will be able to directly measure the changes in ionospheric electron density and electron temperature during the eclipse. They will also be able to observe changes in photoelectron flux and ion-drift.

It's a shame that the first half of that plasma line plot is missing (because we just upgraded the processing computer to Digital RF 2 and needed that time to work out the bugs). It's working fine now though and should be good to go for the eclipse!ReplyDelete
That was a test run to iron out bugs. I've been looking at the start of the eclipse run, and plasma-lines work fine now. I've been using DRF2, and I must say that it was worth the trouble to go to 2.0. All the experimental external scripts and tools that were developed over the years are now standard features, and also the file access times are O(1).Delete
