General Comments:

The manuscript reports observational data collected using 7 TigerShark unmanned aerial systems (UAS) flights and 133 tethered balloon uncrewed platforms flights. All data has been archived and made freely available. The atmospheric research community may find the data valuable for studying spatial variability of atmospheric and surface parameters. Details of acquisition, collection, and quality control of the datasets are provided with a concise discussion of possible scientific contributions based on these platforms. The manuscript is well-written and only requires attention in the introduction as indicated next. When describing recent work with UAS and tethered balloons in lines 25-31 the manuscript does not sufficiently explain recent efforts implemented to study the Earth System with combined approaches. The manuscript should explain the work in a couple of papers: (a) One from Sensors 2019, 19(8), 1914; DOI: 10.3390/s1908191410.3390/s19081914, which used a balloon-launched unoccupied glider with a suite of sensors to measure atmospheric temperature, pressure, and relative humidity in missions beyond visual line of sight. (b) One from Meteorol. Z. 2009, 18, 141–147; DOI: 10.1127/0941-2948/2009/0363 about a small UAS called SUMO for atmospheric boundary layer measurements. Once this matter is addressed in a minor revision, the revised manuscript should be ready for publication.
