Growing stock volume (GSV) is a fundamental parameter of forests, closely related to the above-ground biomass and hence to carbon storage. Estimation of GSV at regional to global scales depends on the use of satellite remote sensing data, although ac

Publikováno v: Journal of Glaciology, Vol 62, Pp 497-511 (2016)

Glaciers and ice caps around the world are changing quickly, with surge-type behaviour superimposed upon climatic forcing. Here, we study Iceland's second largest ice cap, Langjökull, which has both surge- and non-surge-type outlets. By differencing

Great whales have been detected using very‐high‐resolution satellite imagery, suggesting this technology could be used to monitor whales in remote areas. However, the application of this method to whale studies is at an early developmental stage

Assessing snow cover changes in the Kola Peninsula, Arctic Russia, using a synthesis of MODIS snow products and station observations

The very high albedo of snow means that changes in its coverage have a significant impact on the Earth's global energy budget. Thus, Northern Hemisphere snow cover, which comprises approximately 98 % of the global total area of seasonal snow, is resp

Using in situ spectra to explore Landsat classification of glacier surfaces

Autor: W. Gareth Rees, Allen Pope

Publikováno v: International Journal of Applied Earth Observation and Geoinformation. 27:42-52

Glaciers are key to understanding the world's hydrological cycle as well as regional and global climate change. Glacier surfaces metamorphose into a range of zones which have implications for surface energy balance and can be used as a proxy for a gl
