Reiterating the proverb that hindsight is 20/20: a pronounced hint that Cape York's elevation profile was, shall we say subdued, lay in James' "Ripple Map". Note the the more pronounced topo features (the crater north of CY and Cape Trib to the south) produce an increase in dune coverage / magnitude down mean-wind of themselves, while such a feature is lacking with CY.
Wish I'd though of that sooner!  -- Pertinax |

Music to my ears:
From Scott's twitter account: "Looks like we'll pull up at Spirit Point at Cape York (our chosen landfall point at Endeavour Crater) on Friday's (weekend) drive!" Maybe we are there yet, soon. Maybe... -------------------- Need more input ...

Are you able to provide numbers, Matt? The latest update says we had tau = 1.01 on 2668, but the latest (2671) pancams do look hazier than 2668.

Yeah, 1.11 the last two sols, compared to bouncing between 0.9 and 1 most of last week. It's been quite variable, mostly between 0.8 and 1.1 lately. Within 3-6 weeks the variability should decline and a slow and steady drop should commence. And eventually, some of the residual opacity of 0.4-0.5 will be high-altitude clouds that don't impact viz.
Also, a little dust confined to the boundary layer (from nearby lifting, say) can be as bad for viz as a lot of dust distributed through the atmosphere. |

Had a play about with a couple of the MIs that are available now...
...and I couldn't help thinking of the contrast...

[...] Also, a little dust confined to the boundary layer (from nearby lifting, say) can be as bad for viz as a lot of dust distributed through the atmosphere. Thank you Deimos. Would an assumption that most of the current variability in tau is mostly related to variation within the BL be fair? I've been thinking about that recently and your post opened the door to ask! QUOTE Within 3-6 weeks the variability should decline and a slow and steady drop should commence. And eventually, some of the residual opacity of 0.4-0.5 will be high-altitude clouds that don't impact viz. Would the time period spent integrating the MB at Cape York be one during which cloud obs would have a decent chance for being fruitful? Thank you again for your time, Pertinax |

Stitched together a few HiRISE zoom-ins and dropped virtual Oppys onto them to show how big the features and landmarks up ahead are compared to our gal...
