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. [...] 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!

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,
