Inferring vegetation dynamics from long-term satellite records

Description

The project aims at inferring vegetation dynamics from long term satellite records (LTSR). LTSR offer a unique long-term perspective on past changes of vegetation cover, such as changes in annual phenological cycles or long-term productivity. That way, LTSR can be used for fingerprinting climate change impacts on vegetation dynamics over time spans and environmental gradients difficult to tackle with other methods. To face the challenge of sparse data streams, which makes the estimation of subtle changes difficult, we use novel tools from Bayesian statistics.
