Line Plot from Scientific Research

The reconstruction extends back to 1400 ce underlining high year-to-year variability with extreme long-lying and early-melting snowpack duration (black curve), a long-term variability (green dashed curve, 50 yr spline filter) ending with the clear decline starting in the last century (orange curve; piecewise linear regression fit to the reconstruction). Grey band represents the estimation of uncertainty of the reconstruction (+/-2 root mean square error).
