MLS has detected SO2 from from the Kasatochi eruption reaching to 100 hPa see attached map. This is higher than Okmok earlier this month.
This is for 8 August 2008. We are waiting for later dates to process.

MLS observes SO2 and HCl from the Okmok volcano that erruped on 13 July 2008 in Alaska. This is the first time that MLS has positively observed an SO2 signal at 215 hPa (all other cases, SO2 was seen at or above 100 hPa). Note that MLS does not retrieve HCl at 215 hPa or below hence the near zero value is apriori but the high 147 hPa HCl is atmospheric (possibly overestimated due to near zero constraint at 215 hPa and below).
