Time series of summer precipitation anomalies in the MLRYR reconstructed from IGGPRE (a) and RAP (b) data from 1470 to 1850, and time series (c) of total solar radiation flux in summer.

Caption

The abscissa of the red dashed line is 1608, the yellow shading represents the period of weak solar radiation, the purple shading represents the period of strong solar radiation, and the gray dashed line is the plus or minus two standard deviation line of each precipitation sequence.
