Climate Change


Information from Earth Observation satellites is a unique tool for assessing climate change. With historic satellite images going up to 40 years back in time it is possible to map changes against a long baseline of environmental information. Satellite images are synoptic and cover large areas instantaneously and thus reduces the dependency on in-situ data and observations whose validity may only be local.

While climate change is a global phenomenon the implications occur on a local scale. GRAS can assist in mapping the local effects of climate change. Examples include:
  • Assessing local variations in Arctic sea ice, glaciers and snow melt. This is important for industries (mining, hydro power, construction), environment (biodiversity and vegetation) and local livelihoods (hunting, fishing etc).
  • Mapping impervious surfaces in urban areas to model the detailed effects of increased precipitation
  • Mapping changes in sea and land surface temperatures and vegetation cover for carbon accounting purposes

Please contact GRAS for more information about monitoring climate change. You may also find more examples in our list of projects.
