Vegetation Productivity Losses Linked to Mediterranean Hot and Dry Events

Persistent hot and dry conditions play an important role in vegetation dynamics, being generally associated with reduced activity. In the Mediterranean region, ecosystems are adapted to such conditions. However, prolonged intense heat drought or occurrence of compound events may still have a negative impact on This work aims study how productivity is affected by events, examining set severe episodes that occurred three different regions (Iberian Peninsula, Eastern Western Europe) between 2001 2019. The analysis relies remote sensing products, namely Gross Primary Production from MODIS detect monitor vegetative stress LST SM ESA CCI evaluate influence temperature soil water availability stressed vegetation. Of all 2005 episode Iberian Peninsula was most significant, affecting large sectors low tree cover areas crops leading reductions annual plant ~47 TgC/year. obtained results highlight land-atmosphere coupling clarified warm springs activity moisture amplify summer temperatures. functional recovery after these varied across ranging months years. highlights basin usefulness remote-sensing products assess response land covers episodes.
