Using 20 years of AVHRR data to assess the impact of the North Atlantic Oscillation on European vegetation
instrument. The year-to-year variations of vegetation greenness in Europe were estimated and related the North Atlantic Oscillation- NAO. Here, we intend to show the sequence of intermediate relevant physical mechanisms responsible for the changes induced in vegetation by the NAO. Therefore, upper l...
