چکیده

We study the response of the land-surface to prescribed atmospheric forcing for 31 May 1978 at Cabauw, Netherlands, using the land-surface scheme from the Coupled Atmospheric boundary layer-Plant-Soil (CAPS) model. Results from model runs show realistic daytime surface fluxes are produced using a canopy conductance formulation derived from Cabauw data (for 1987, a different year), and un-tuned parameterizations of root density (nearuniform with depth) and soil heat flux (reduced thermal conductivity through vegetation). Sensitivity of modelcalculated surface heat fluxes to initial values of soil moisture is also examined. Results of this study provide the land-surface ‘base state’ for a coupled land–atmosphere modeling study.

Assessment of the Evapotranspiration and Surface Fluxes in the Framework of the Land-saf: Methodology and First Results

This contribution presents the methodology we are currently developing in the framework of the EUMETSAT Land-SAF to estimate the evapotranspiration all over Europe by means of Satellite Remote Sensing (SRS). We present here the first validation results with data from two meteorological sites (Cabauw, MUREX) and output of the model run on a low resolution grid laid over Europe, for selected hour...

Surface Water Quality Evaluation under Land Use Changes (Case study: Mahabad Chai Watershed)

Not only have recent global challenges including drought, climate change, land degradation and land use change impacted the quantity of available surface water and groundwater, but also water quality has been affected as well. To study this impact, Landsat 5 satellite images and water quality data were obtained to compare the effects of land use changes on surface water quality between July of ...

Remote sensing for urban heat and cool islands evaluation in semi-arid areas

Cities are experiencing rapid population growth and consequently extensive urbanization. Land-use/land-cover change is one of the important elements worldwide, which significantly affect the environment. This study aims to describe the emergence of urban heat and cool islands as a result of changes in land-use/land-cover. Land surface temperature over a 32-year period in Isfahan city, Iran was ...

The Probability Distribution of Land Surface Wind Speeds

The probability density function (pdf) of land surface wind speeds is characterized using a global network of observations. Daytime surface wind speeds are shown to be broadly consistent with the Weibull distribution, while nighttime surface wind speeds are generally more positively skewed than the corresponding Weibull distribution (particularly in summer). In the midlatitudes, these strongly ...

The land - surface flux model PROGSURF ́

Ž . The land-surface flux model PROGSURF designed jointly at the Universities of Vienna and Budapest is reviewed; it belongs to the broad spectrum of PILPS 1 models. PROGSURF comprises one vegetation layer and three soil layers. Temperature prediction is made by the heat conduction equation in conjunction with the force-restore method. Turbulent heat fluxes are parameterized by gradient laws us...
