Flowers in your hair (and little aerosols in the air)

June 6th, 2010 by mottaviani

There’s always a lot of people thanking each other in a campaign, but today the crew, the pilots, and whoever up there is responsible for good weather deserves all my kudos. I normally don’t get to sit on the airplane, as our instrument works as a Swiss clock and we prefer to save fuel to pull longer flight legs. Today the circumstances were atypical and I got to board, curiously on the day of the one-year anniversary form my previous flight, during the RACORO campaign in Oklahoma.

It's a long way into aerosol research. This is Rt. 80, Eastbound to Reno, NV. Haze is alway more visible when looking toward the horizon, as an effect of the longer line of sight that maximizes scattering effects and overexposes pictures because of the amount of diffuse light.

Touristic companies would have a hard time to match the quality of this Tour of California (and I didn’t have to pay for it). I have to share these pictures, although their quality doesn’t speak enough of the true beauty of the sight. In my partial defense, I must say that the small B200 is extremely crammed and taking a good shot requires leaning over the pilots, which is not something you want to do too often (all other windows are partially darkened).

Taxing on the SMF runway, ready for takeoff. The preamble to a fab flight.

The route led us South of Sacramento along the San Joaquin valley, majestically shouldered by the Sierras still loaded with late spring snow.

Yosemite Valley. You can't miss the distinctive silhouette of Half Dome and (below it, on the other side of the valley) the climbing legend of El Capitan, the largest block of monolithic granite in the world. Further in the background is Mono Lake, before the terrain rises up again toward Boundary Peak and Thousand Lakes Mountain, a ridge dividing California from Nevada. Look at how much snow is still in the High Sierras! A million dollars (and a million years) view.

Fresno marked our big right turn toward the coast, right about when we spotted a small fire in the San Benito region.

Something burning down there. Exactly the stuff we like to fly over (a bit too far south for today's route).

The flight plan required overpassing some ground stations at NASA Ames and in Monterey, so we were absolutely forced to come back along the Big Sur. Absolutely. It truly is a glorious coastline with surf clearly visible even from a 9km altitude. Cloud banks were innocuously looming from the ocean, a single tongue of fog daring to come further right there where it should be.

San Francisco Bay. The Golden Gate Bridge furtively peers through the fog, which gently rolls over the Presidio coming to a close with Alcatraz. A chilling sight. The Bay Bridge is barely visible at the bottom right.

The final stretch was over the valleys of Napa and Sonoma, and shortly before touchdown over the only cloud bank the plane had to overfly.

I finally want to mention that yesterday was also “media” day. Here and here is what came out of it. By the way, if you happen to watch the videos, you should note that even if Rahul investigates scientific principles, that doesn’t make him a “principle investigator” as the banner reports. He’s the “principal investigator”. Don’t mean to brag too much about it, it’s just a matter of principle. Since we’re at it, measuring the composition of particles requires a “spectrometer” rather than an “aspectrometer”. Well, in a way we’re measuring the aspect of particles.


Media day, aka "What the heck is he talking about?"
