[Termes IGN] surface hétérogèneRésumé : (Auteur) Evapotranspiration is an important part in surface energy balance and water balance. Compared with other methods (micrometeorological, climatological, or hydrological method), the remote sensing model has obvious superiority to estimate regional evapotranspiration over heterogeneous surfaces. In this study, based on Landsat TM/ETM+ data and meteorological data, evapotranspiration in Beijing area on 17 April 2001, 12 April 2002, 06 July 2004, 06 May 2005, and 22 May 2005 were calculated by an estimation model of regional evapotranspiration. Comparisons of energy balance components (net radiation, soil heat flux, sensible and latent heat flux) with measured fluxes were made integrating the remotely sensed fluxes by the footprint model. Results show that latent heat flux estimates (adjusted for closure) with errors (MBE1RMSE) 26.47142.54 Wm-2, sensible heat flux error of -8.56123.79 Wm-2, net radiation error of 25.16150.87 Wm-2 and soil heat flux error of 10.68122.81 Wm-2. The better agreement between the estimates and the measurements indicates that the remote sensing model is appropriate for estimating regional evapotranspiration over heterogeneous surfaces. Furthermore, the spatial distribution of evapotranspiration in Beijing area was analyzed.

[Termes IGN] ruissellementRésumé : (Auteur) Rainfall interception by vegetation is an important factor in the water balance. Consequently, rainfall interception should also be an important factor in models simulating processes such as evaporation, transpiration, surface runoff, soil erosion, and crop growth. In practice, however, it is difficult to make quantitative assessments of the spatial and temporal distribution of rainfall interception loss at the catchment level, for instance, and to make these values available as model input. In this paper, we present a novel method using earth observation images to estimate local quantitative values of rainfall interception loss. Leaf Area Index (LAI) and fractional vegetation cover per grid cell are important process variables for rainfall interception. These two variables are estimated from images using spectral vegetation indices and using spectral mixture analysis, respectively. Relations between canopy storage capacity and LAI exist for several plant species and vegetation types, but limited data are found on crops, and more research is needed in this field. The new method is explained and illustrated for a study area in southern France with a variety of land-cover types. It is found to be a valuable and practical approach to quantitatively assess spatial patterns of interception loss for given rainfall events.

[Termes IGN] simulationRésumé : (Auteur) A precise simulation of soil water content (SWC) and actual evapotranspiration (ETa) in a region or a catchment depends on the accuracy of the spatial data inputs. In this study, we developed a simple grid-based soil water balance model. In this model, remotely sensed vegetation data are used to estimate spatial distributions of daily SWC and ETa rates. The model was validated by comparing simulated SWC with the measured by gravimetric method and time domain reflectometry (TDR) at an experimental test site located in Northeastern Germany in the time period 1993–1998. The index of agreement IA and the root-mean-square error obtained from the comparison of the TDR measurements to the simulated values ranged from 0.45 to 0.80 and from 0.029 to 0.061 cm3/cm3, respectively. The comparison of simulated ETa rates to those measured by four large-scale lysimeters at another test site showed IA values above 0.87 and R2 values higher than 0.59. For the regional application of the model, a method was developed to integrate the Moderate Resolution Imaging Spectrometer (MODIS) vegetation data into the model. The MODIS data used in our study consist of 16-day normalized difference vegetation index and 8-day leaf area index products. Regarding the spatial application of the model, our approach was tested in a catchment located in Northeastern Germany in 2001–2003. A sufficient correlation between daily discharge rates measured at two observation gauges in the catchment and the corresponding simulated discharge rates and also good correlations between the simulated ETa rates and the MODIS-leaf area index values indicate that the model is an appropriate simulation tool at regional scale if the corresponding additional spatial databases regarding surface and soil properties are available.

[Vedettes matières IGN] Végétation et changement climatiqueRésumé : (auteur) Heat and drought were extreme in summer 2003 in Europe. Climatic data show that most extreme were maximum air temperatures in June and August; maps of these two months show a striking similarity in geographical range. Over wide regions, monthly mean temperatures were more than 4 °C above the long term mean values. The heat lasted from May to September in large parts of western and central Europe. The lack of precipitation was most severe in summer 2003 but precipitation was generally below normal from February 2003 until June 2004 (with the exception of two months). Sunshine duration was above normal, particularly in regions which usually have rainy and cloudy episodes in summer, and relative air humidity was below normal during the whole year of 2003. The drought experienced by the vegetation in summer 2003 was exacerbated by the length of the period with scarce precipitation and humidity, by the heat during the summer and by long sunshine duration.
