Satellite-derived precipitation can be a potential source of forcing data for assessing water availability and managing water supply in mountainous regions of East Asia. This study investigates the hydrological utility of satellite-derived precipitation and uncertainties attributed to error propagation of satellite products in hydrological modeling. To this end, four satellite precipitation pro...
For the area of the United States the Shuttle Radar Topography Mission (SRTM) height models are available with 1 arcsec spacing instead of the 3 arcsec spacing outside the country. Only special users are getting the 1 arcsec height information outside the USA. 1 arcsec and also 3 arcsec SRTM height models have been investigated in a mountainous area, covered nearly completely by forest, in an u...
[1] An analytical algorithm for the determination of land surface temperature and soil moisture from the Tropical Rainfall Measuring Mission/Microwave Imager (TRMM/TMI) remote sensing data has been developed in this study. The error analyses indicate that the uncertainties of the enrolled parameters will not cause serious errors in the proposed algorithm. By applying the proposed algorithm to T...
Mountain regions are hotspots of biodiversity, and particularly sensitive to human activities global changes. Characterizing biodiversity using trait-based approaches may improve the understanding evolutionary mechanistic basis ecological patterns in species distribution. The investigation trait–environment relationships, however, is challenging, especially when a hierarchical sampling design u...
Major changes in the vegetation and consequently in the ecosystem functioning of mountainous meadows has been reported in response to herbivore grazing. Nevertheless, effects of protection from herbivores on the vegetation of High-elevation meadows in Iran have not been studied so far. To assess effects of experimentally short-term exclosure treatment on production of mountainous meadows, two m...
The basis of spatial planning is the geomorphological zoning of ground surface, in which the first phase is determining the homogeneous zones of the ground surface in terms of geomorphological characteristics. The current study aimed at determining the proper zones for artificial feeding in Gahar mountainous region and Garebayegan plains in Fars province by the use of zoning the ground by Evans...
Footwear worn by U.S. military aircrew personnel provides inadequate levels of protection from a prolonged cold and wet exposure when compared with that wore by ground-based, combat troops. On June 2, 1995, a U.S. Air Force F-16 C aircraft was shot down by a mobile SA-6 surface-to-air missile over Bosnia-Herzegovina while conducting a routine NATO reconnaissance mission. The pilot survived the ...
