The story of the HMS Soltis – the red balloon
Overcast conditions, though the clouds were high. No wind. The surface temperature was significantly higher at the end of the launch compared to the beginning. The layer reached isothermal around 40m. The dewpoint stayed fairly constant, but it bowed in just a tad at the mid-layers.

Temperature cooled slightly with height, though the layer was close to isothermal. Dewpoint temperature was substantially different from 0m to 40m between ascent and descent. The ascent of the sonde recorded a much drier lower level.

The lowest 15m of the layer cooled with height slightly before a small inversion occurred from 15m to 30m on both the ascent and descent. The rest of the layer was isothermal. Dew point remained nearly isothermal except in the lowest 5m. As such, the relative humidity fluctuated very little separating only slightly near the [...]

Night launch. After three hours of darkness, the nocturnal inversion, in which temperature increases with height, had already occurred. Temperatures warmed to about 25m before becoming isothermal. Relative humidity was drier on descent from 55m to 5m because temperature warmed and dewpoint cooled when compared to the ascent. The cooling dew point suggests a less [...]

This special launch occurred during a period with very low cloud base around 50m off the ground. Temperatures cooled just slightly near the surface and then were isothermal. The dew point and relative humidity decreased with height to 20 m and then increased rapidly to 25 m where the balloon entered the cloud and RH [...]
