PollyXT is a 15-channel lidar system optimized for dust:

  • 3 backscatter coefficients (355, 532 1064 nm)
  • 3 extinction coeff. (355, 532,1064 nm)
  • 3 depolarization ratios (355, 532, 1064 nm)
  • Water vapor
  • Near range detector: data from 100 m height
  • Diode pumped laser (100 Hz)
  • Automatic data visualization and processing in PollyNET (picasso.tropos.de)
