A comparison of DGA hourly surface air temperature with 2-m temperatures at the five Tinytag sites is shown in Figure 4.
Mean hourly (22-26 March 2015) lapse rate data for various pairs of 2-m sensors are given in Table 3.
These early afternoon large drops/reversals in lapse rates are mainly related to the diurnal temperature peaking one hour later at S3 (Station 2) compared with the lower S6 (Station 4) and S2 (Station 5)--and indeed the other two S4 and S5 2-m LogTags--sites; the only other site with peak temperature at 18:00 (in common with S3/Station 2) is DGA.
Comparison of Temperatures at 1-m and 2-m Heights above Glacier Surface.
The generally greater temperatures at 2-m can be attributed to boundary-layer effects of a cold ice surface having a stronger influence on suppressing air temperatures nearer the surface during daytime, especially under conditions of strong solar radiation, and heat loss through infrared radiational cooling lowering the surface temperature more during night time.
Daily mean and mean daily (22-26 March 2015) temperatures for all ten Tinytag sensors (1-m and 2-m elevation at five sites) are reported in Table 6, and daily mean and mean daily lapse rates between various pairs of Tinytags are given in Table 7.
Figure 8 shows the mean daily lapse rate profiles for various pairs of sites (e.g., between 2-m Tinytags in Figures 8(a) and 8(c) and 1-m Tinytags in Figures 8(b) and 8(d)).
Temperatures at 1-m and 2-m heights above the surface are generally similar, within 0.5[degrees]C, but occasionally vary by as much as [+ or -]4[degrees]C, depending on changes in the surface energy budget and in the ambient meteorological conditions.
