Impact of Deforestation on the
Sustainability of Biodiversity in the Mesoamerican Biological Corridor
7.1 Dry day
Table 3a,b shows temperature, LH, SH, PBL height, precipitation and cloud cover for the
south (pasture) and north (forest) sides for both a representative dry day (March 8) and a
representative convective day (March 23) as a function of time (0600, 1000, 1200, 1400 and
1800 LT). These are values averaged over each of the two sides, forest to the north and
pasture to the south.
