The Variable Infiltration Capacity (VIC) macroscale hydrologic model is distinguished from other Soil–Vegetation– Atmosphere Transfer schemes (SVATS) by its focus on runoff processes. These are represented via the variable infiltration curve, a parameterization of the effects of subgrid variability in soil moisture holding capacity, from which the model takes its name, and a representation of n...

in this study, the radial distribution and gravimetric storage capacities of hydrogen on coronene (c24h12) and its si substituted forms, c24h12, c24-nsinh12 (n= 4-24), have been investigated at 298 k and 0.1 mpa (standard situation) using (n,v,t) monte carlo simulation by lennard-jones (lj) 12-6 potential. the results show that the increase of number of silicon substitution doesn’t have any eff...

abstract having no exact knowledge of most appropriate harvesting time in kiwifruit grown in different regions of guilan province, as well as the low storage longevity of the fruits are the most important factors causing considerable reduction in both marketability and export affairs. in this study, the influence of fruit quality in term of harvesting time on the postharvest quality and food va...

We incorporated a single-layer urban canopy model into a simple two-dimensional atmospheric model in order to describe the fundamental impact of the urban canopy model on an idealized urban heat island simulation. We found that the heat island circulation developed less strongly than when using the atmospheric model with the standard slab urban model. Additionally, the coupling with urban canop...

Quantifying the mechanistic links between carbon fluxes and forest canopy attributes will advance understanding of leaf-to-ecosystem scaling and its potential application to assessing terrestrial ecosystem metabolism. Important advances have been made, but prior studies that related carbon fluxes to multiple canopy traits are scarce. Herein, presenting data for 128 cold temperate and boreal for...

BACKGROUND AND AIMS The light availability on a temperate, deciduous-forest floor varies greatly, reflecting the seasonal leaf dynamics of the canopy trees. The growth and/or reproductive activity of understorey plants should be influenced by the length of the high-irradiance period from snowmelt to canopy closure. The aim of the present study was to clarify how spring-blooming species regulate...

Efforts inEurope to convertNorway spruce (Piceaabies) plantations tobroadleaf ormixedbroadleaf-conifer forests could be bolstered by an increased understanding of how artificial regeneration acclimates and functions under a range of Norway spruce stand conditions. We studied foliage characteristics and leaflevel photosynthesis on 7-year-old European beech (Fagus sylvatica) and pedunculate oak (...

Measurements of turbulent exchange in the understorey of a forest canopy are necessary to understand and model both the functioning of the lower stratum and its contribution to turbulent exchange at the whole canopy scale. Eddy covariance measurements of eddy fluxes just above the floor of a forest canopy must be thoroughly validated, given the particular conditions prevailing there. Our object...

[1] This paper addresses the effects of canopy physical processes on snow mass and energy balances in boreal ecosystems. We incorporate new parameterizations of radiation transfer through the vegetation canopy, interception of snow by the vegetation canopy, and under-canopy sensible heat transfer processes into the Versatile Integrator of Surface and Atmosphere (VISA) and test the model results...
