Actual installation heights (in metres) of meteorological data at the nominal 2/6/10 m positions of the tower and on the ASFS.

Variable	2 m	6 m	10 m	ASFS30	ASFS40	ASFS50
Temperature	1.75 (1.1–2.2)	5.44 (4.8–5.9)	9.34 (8.7–9.8)	2.13 (1.2–2.4)	2.13 (1.9–2.2)	2.13 (1.6–2.4)
Relative Humidity	1.46 (0.8–1.9)	5.24 (4.6–5.7)	9.14 (8.5–9.6)	1.84 (0.9–2.1)	1.84 (1.6–1.9)	1.84 (1.3–2.1)
Pressure	1.65 (1–2.1)	N/A	N/A	1.92 (1.0–2.2)	1.92 (1.7–2.0)	1.92 (1.4–2.2)
Wind/Turbulence	2.66 (2–3.1)	5.68 (5–6.1)	10.54 (9.9–11)	3.86 (3–4.2)	3.86 (3.6–3.9)	3.86 (3.3–4.1)

Note that these are installation heights that changed in time with accumulation and ablation of the surface, which was monitored locally using the sonic ranger. The range of the temporal variability in height is represented in parentheses.
