Use Infinity ND:YAG laser: 370 mJ and 50 Hz at 1064-nm (New)


Observers:  Leona/Erika   11:30 ~ 13:00 
            cao/viviana   15:00 ~ 16:30 
            Fanny/wu      16:30 ~ 18:00 

Weather status: haze 
          

Lidar status:
  Have a break over 13:00~15:00 due to heat-wave and moisture (~36 C)

  Change filters due to strong signals from haze
  NDF=0.5 at 1064-nm 
  NDF=2.5 at 532-nm 
  same NDF at 355-nm
