Fig. 3: Impact of spatial resolution in the speed of microclimate velocities.
From: Microclimates slow and alter the direction of climate velocities in tropical forests
Microclimate velocity (m yr−1), the temporal rate of climate change (°C yr−1) and the spatial gradient of climate change (°C m−1) in the northern range of Trinidad calculated at 1-km, 100-m and 20-m spatial resolutions within the forest. Microclimate velocity calculations account for impacts of topography and vegetation on climatic variability. Land-surface velocities are calculated in 2D at 2 m above ground and within-canopy velocities are calculated in 3D at 5-m vertical intervals within the upper half of the canopy. Boxplots display median and 25th and 75th percentiles, with upper and lower whiskers corresponding to 1.5× IQR from the 25th or 75th percentiles. Note that y axes differ between maximum and minimum temperatures and are truncated at the upper end to aid visualization. Sample size (n grid cells) used to produce boxplots represent a 15% random sampling of each category. Maximum temperature: nland-surface, 1km = 371; nland-surface, 100m = 42,906; nland-surface, 20m = 1,027,724; nwithin-canopy, 1km = 814; nwithin-canopy, 100m = 83,087; nwithin-canopy, 20m = 1,944,640. Minimum temperature: nland-surface, 1km = 373; nland-surface, 100m = 43,105; nland-surface, 20m = 1,034,544; nwithin-canopy, 1km = 814; nwithin-canopy, 100m = 83,083; nwithin-canopy, 20m = 1,944,548.
