snow is one of the main components of hydrological cycle in most of mountainous basins. since collecting the snow data (e.g. snow water equivalent data) is very difficult and time consuming, some effort is necessary to develop methods to estimate spatially variation of snow depth distribution. in the present study, the at-site swe data of 14 stations located in the west of isfahan providence fo...

A warm, very wet Paci®c storm caused signi®cant ̄ooding in the Paci®c Northwest during February 1996. Rapid melting of the mountain snow cover contributed to this ̄ooding. An energy balance snowmelt model is used to simulate snowmelt processes during this event in the Central Cascade Mountains of Oregon. Data from paired open and forested experimental sites at locations at and just below the Pa...

accurate estimation of crop evapotranspiration (etc) plays an important role in improving the water useefficiency (wue) and water management. due to the presence of different types of coatings plant in large areas, the accurate calculation of the water requirements by conventional methods is elusive or impossible. remote sensing methods are becoming attractive to estimate crop evapotranspiratio...

Airborne passive-microwave signatures collected in Northern Finland during EMAC-95 are analyzed with the emphasis on forested areas and dry snow conditions. The microwave signatures cover the 6.8–18.7-GHz frequency range and were acquired at both vertical and horizontal polarizations. The analysis is carried out with respect to the forest-stem volume data and comprises three different snow-dept...

An evaluation of the Biosphere±Atmosphere Transfer Scheme (BATS) snow submodel was conducted, both in a stand-alone mode and within the National Center for Atmospheric Research (NCAR) Community Climate Model version 3 (CCM3). We evaluated, in the stand-alone mode, the performance of BATS parameterizations at local scales using ground-based observations from the former Soviet Union and fromMammo...

Snow is important for water management, and an important component of the terrestrial biosphere and climate system. In this study, the snow models included in the Biome-BGC and Terrestrial Observation and Prediction System (TOPS) terrestrial biosphere models are compared against ground and satellite observations over the Columbia River Basin in the US and Canada and the impacts of differences i...

Seasonally snow covered areas of the mountain ranges are important components in the global hydrologic cycle. Therefore monitoring the extent of the seasonal snow cover and the accumulation and ablation zones of glaciers is essential for understanding of the global hydrologic cycle, one of the objectives in the study of the Earth sciences. Seasonal snow cover is the major source of the fresh wa...
