, Y Rezaei; , M.J. Valadan Zouj; , M.R Sahebi

Volume 9, Issue 1 , October 2017, Pages 1-16

Abstract
  Mountain Glaciers are pertinent indicators of climate change and their surface velocity changes, are an essential climate variable. In order to retrieve the climatic signature from surface velocity, large scale study of glacier changes is required. Satellite remote sensing is an effective way to derive ...  Read More
