The PollyXT lidar is a fully automated instrument capable of 24/7 operation (Engelmann et al., 2016). It is equipped with:

• Three (3) elastic backscatter channels, at 355nm, 532nm and 1064nm.
• Two (2) rotational-vibrational Raman channels, at 387nm and 607nm.
• Two (2) linear depolarization channels at 355nm and 532nm.
• One (1) water vapor detection channel at 407nm.
• Two (2) near field elastic backscatter channels, at 355nm and 532nm.
• Two (2) near field rotational-vibrational Raman channels, at 387nm and 607nm.
