RF: Well, heading towards Brasilia. We're 100 miles out. We've got pretty uniform altocumulus above us. Some scud down below near the surface. Very little cloud between about 500 ft off the surface and maybe 12- to 13,000 ft above. And we're just sampling this haze in the region. It seems cleaner here than it was on the earlier two legs of the flight and certainly cleaner than it was north of Porto Nacional. Lower particle count and scattering. Not much evidence of smoke. Occasional drizzle on the windscreen coming from something up there.

RF: A quick summary here of flight 1715. Uniform haze between cloud layers. Didn't see much of anything. A little bit of drizzle hit us while we were going towards Brasilia. Very clean air. Some of the cleanest air we've seen since we've been in Brazil. Did background sampling. A lot of hot and cold DMPS and humidigraph and nothing at all resembling fires or burnt areas between Porto Nacional and Brasilia. So, I'm a little bit at a loss about what we will do if we want to work in this area any more.
