The thermal evaluation of snow line and identification of potential areas of snow falling in the Alborz Mountains with NOAA-AVHRR images
Abstract The extention of Snow cover and its spatial and temporal changes considered as a basic parameter in climatic and hydrologic studies. Data from satellite images due to the low cost and the large extention of cover are, effectively help the identifying of the snowy basins. Since the satellites are able to imaging a surface at different times, this will allow snow survey studies to inves...
متن کاملexamining the relationship between fear of negative evaluation and communication strategies by iranian efl learners
the purpose of the present study was to investigate the relationship between fear of negative evaluation (fne) and communication strategies (css) among iranian efl learners. it was aimed to examine the differences in the use of communication strategies between speakers with high or low degree of fear of negative evaluation. the current study was a case study consisting of 10 english learners at...
Automatic Noaa Avhrr Image Registration in Mountains Area
This article presents a new and novel approach to accomplish AVHRR data navigation with errors of less than 0.9 km in the middle latitude regions. The AVHRR channel 4 counts and GTOPO30 elevation data and image correlation method are used. This approach is suitable for both day and night passes. It can also be used for other satellites with thermal sensing radiometers. A two steps approach is i...
متن کاملSnowmelt Contributions to Runoff in an Extremely Wide Altitude Range from Large Area Satellite Imagery
Based on periodical snow cover mapping by NOAA satellites, contributions to runoff from seasonal snow cover, intermittent snowfalls and rain are evaluated in relation to the altitude in the basins of the rivers Ganges (917 444 km) and Brahmaputra (547 346 km) in an altitude range from 0 to 8848 m a.s.l. In spite of insufficient precipitation and temperature data, runoff was simulated with an ac...
متن کاملEvaluating MODIS snow products for modelling snowmelt runoff: Case study of the Rio Grande headwaters
Snow-covered area (SCA) is a key variable in the Snowmelt-Runoff Model (SRM) and in other models for simulating discharge from snowmelt. Landsat Thematic Mapper (TM), Enhanced Thematic Mapper (ETM + ) or Operational Land Imager (OLI) provide remotely sensed data at an appropriate spatial resolution for mapping SCA in small headwater basins, but the temporal resolution of the data is low and may...
