Ultrasonic anemometer and doppler lidar wind and gust data products during FESSTVAL 2021

dlidcsm_level1: This data set contains the level-1 data of the Doppler LIDAR measurements at the three supersites (Falkenberg, Lindenberg, Birkholz) operated during the Field Experiment on Sub-mesoscale Spatio-Temporal Variability in Lindenberg (FESSTVaL) during the period May 17 to August 31, 2021 (please also see the "Additional Notes" further down on this web page). dlidcsm_level2: This data set contains two wind products: (i) vertical profiles of the mean wind vector and (ii) vertical profiles of wind gusts derived with two different kinds of processing (Level2dwd and Level2uzk, see "Methods") from the Doppler LIDAR level 1 data dlidcsm_level1. sonic: This data set contains level 2 data of the mean wind vector and of the maximum gust wind speed derived from ultrasonic anemometer measurements at heights of 2.4 m, 50.3 m and 90.3 m at the Grenzschichtmessfeld (GM) Falkenberg during the Field Experiment on Sub-mesoscale Spatio-Temporal Variability in Lindenberg (FESSTVaL) over the period May 17 to August 31, 2021. The GM Falkenberg as part of the Lindenberg Meteorological Observatory – Richard-Aßmann-Observatory supersite is operated by the German national meteorological service (Deutscher Wetterdienst, DWD).
