Why use SAR?
The data can be used for a number of purposes
- Validate the SAR measurements using FLUX tower site characterization data
- Examine the impacts of vegetation dynamics on climate
- Understand human impacts on vegetation at a local scale
- Detect deforestation and forest degradation
- Map and differentiate forest growth stages and change
- Retrieve woody biomass and structural attributes; and
- Characterize, map and monitor ecoregions such as mangroves and wetlands.
