Roles of forests in moderating the diurnal cycle of land-atmosphere interactions

However, understanding the contributions of dense forests remains challenging due to observational limitations. Our in-situ observations show that forests regulate the diurnal temperature range by approximately 2 °C compared to open fields.

The Community Terrestrial System Model simulation reveal that latent heat and sensible heat fluxes are overestimated by around 10% during the daytime. The nighttime temperatures are underestimated when biomass heat storage (BHS) is excluded. Furthermore, the Single-Column Atmospheric Model indicates that the misestimated daytime heat flux leads to the slight overestimation of boundary layer height.
