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.
