Sensitivity of CO<sub>2</sub> and CH<sub>4</sub> Annual Cycles to Different Meteorological Variables at a Rural Site in Northern Spain

<div>Annual evolution of the recirculation factor (RF) and CO<sub>2</sub> (a) and CH<sub>4</sub> (b) during the night. Three situations were considered: with all the observations (cyan line), for recirculation factors above 0.15 (red line), and for recirculation factors below 0.02 (green line). The appearance frequency for the low and high recirculation factor is also shown.</div>
