Abstract:
Water vapor measurements from the newly developed ATMONSYS DIAL
system are presented. Besides the presentation of the overall system capabilities, we show that the system, in combination with Doppler wind lidars, is able to capture vertical fluxes of latent heat. In addition, we show a substantial natural short-term relative variability of humidity inside the PBL of ~20%. Finally, an extended intercomparison of 3 humidity lidars and radiosondes shows that the drift of the radiosondes can have substantial implications
