Seasonal Vegetation Trends for Europe over 30 Years from a Novel Normalised Difference Vegetation Index (NDVI) Time-Series—The TIMELINE NDVI Product

Remote sensing multi-decadal time-series provide important information for analysing long-term environmental change. The Advanced Very High Resolution Radiometer (AVHRR) has been providing data since the early 1980s. Normalised Difference Vegetation Index (NDVI) derived thereof can be used monitoring vegetation conditions. This study presents novel TIMELINE NDVI product, which provides a consistent set of daily, 10-day, and monthly composites at 1 km spatial resolution based on AVHRR Europe North Africa, currently spanning period from 1981 to 2018. After investigating temporal availability within composite seasonal trends have 1989–2018 assess change in northern Africa. trend analysis reveals distinct patterns with varying spring, summer autumn different regions Europe. Integrating entire growing season, result shows positive large areas that confirm reinforce previous research. analyses show product allows dynamics monitored pan-European scale detection specific regional patterns.
