DESCRIPTION:Speakers: Bin Ma (Sun Yat-sen University)\n\nFollowing the ins
 tallation of two DIMMs at Kunlun Station\, Dome A in early 2019\, we were 
 able to directly measure astronomical seeing through the winter for the fi
 rst time.  At a height of just 8 meters\,  the seeing was detected as good
  as 0.13 arcsec. For 31% time\, it was free of boundary layer turbulence\,
  and consequently was the free-atmosphere seeing only\, with a median of 0
 .31 arcsec.   We also find that the seeing and boundary layer thickness ar
 e correlated with local temperature inversion which is monitored by KLAWS\
 , a multi-layer automatic weather station.  Then we confirm that the media
 n boundary-layer thickness is about 14 m\, while it is 30 m at Dome C. The
 se results further support Dome A to have the best conditions for optical/
 infrared astronomy.\n\nhttps://events.icecube.wisc.edu/event/144/contribut
