At this time of year, deciduous trees across Europe are losing the last of their leaves. When will they come into leaf again? A study just published in Nature Communications has shown that while year-to-year leafing date variations can be explained by heat accumulation, local climate is a key factor in geographical variations.
With a view to improving access to and the availability and use of geospatial data, the intergovernmental partnership GEO (Group on Earth Observations) has this year established a GEO Associate membership category for organizations based anywhere in the world and related to such data. CREAF recently became one of the first six GEO Associates.
