Average

Ring:

The average ring represents the average annual moisture in the upper layer of the soil during 1950-2005.  For every 3% increase in annual soil moisture the rings are darker and further apart, for every 3% decrease the rings are lighter and closer together.  In the 2090s soil moisture will average 7% less than during the last half of the 20th century.  For more info see technical notes.
