Figure 3: Correlations of terrain elevations with observed isoprene EFs and top-down isoprene emissions.

From: Airborne observations reveal elevational gradient in tropical forest isoprene emissions

Figure 3

The median values of isoprene EFs estimated from EC approach (red diamond), top-down biogenic isoprene emissions based on satellite data including GOME-2 (purple triangle) and OMI (blue square), and their 25% quartile values (lower bar) and 75% quartile values (higher bar) during dry (a) and wet (b) seasons compared with terrain elevations with an interval of 30 m. The black dot lines indicate the EF used in MEGAN v2.1. The colour dash lines show linear regressions for median values from each approach, and their correlation coefficients (R) are shown in the figures.
