Comments = Beautiful SDI data!  Takeshi Sakanoi told me there was a patch of snow on the SDI dome until about 09 UT - when he cleared it off.  It was either too small or too thin to degrade the horizontal winds much, according to the data.  Vertical winds before then would be unreliable.  There is a huge vertical wind event at 09:37 UT - AFTER Takeshi cleaned the dome.  We need to look at this!
