Phenology is the response of biological organisms to seasonal variations in environmental factors like light, temperature and precipitation. Changing growing seasons are important indicators of changes in the climate system. Also short-term variations may indicate disturbances that may seriously affect production and health of the vegetation. Use of satellites for monitoring phenology is a way of improving our knowledge base concerning vegetation-climate interactions.
- Development of a new vegetation index for better description of phenology from Earth observation data. The new vegetation index is further described here.
- Developing mechanistic phenological models driven by climate data for common forest species. For more information on phenology modeling follow this link.
- Improving descriptions of vegetation phenology in a current ecosystem model (LPJ-GUESS)
- Predicting effects of climate change on phenology of Swedish forest species
- Studying effects on Swedish forestry and necessary adaptations of forest management
We carry out a number of activities including spectral measurements, deployment of phenology cameras, model development, use or carbon flux measurements, and processing of MODIS satellite data. NDVI and other vegetation indices are tested for monitoring the phenology of sub-arctic and boreal tree species.
