I visited this data early on, but there's 600+ sols worth now, so I've revisited it
I thought it would be interesting to comapre Tau values form both rovers at the same time - so to that end I added 21 to the sol number of each Opportunity tau observation to bring it in to line, within a sol, of Spirit observations. What does it show? (remember to subtract 21 to get ACTUAL Opportunity Sol numbers) Well - both rovers experience a large increase from around Sol 350-370, but for Opportunity it peaked briefly significantly higher. Spirit experienced two local events, 380 and 420, Opportunity a long, small peak around 450 and another, shorter one at 480, and the share the big spike at 510ish. Interesting stuff anyway - when you match them up, time wise ( i.e. +21 on MERB sol numbers ) they match quite closely. Doug

Doug Nice chart: weird how Tau always increases as a huge spike that then levels off. I guess dust only is replenished back up into the high levels of the atmosphere during storm-like events, so a sudden burst of dust hits a site all at once and then tapers off slowly as the dust settles out? Do we have about another 100 Sols before the next storm season begins? |
