Surface mass balance along the K-transect in West Greenland, 1990-2011

A 21-year record is presented of surface mass balance measurements along the K-transect. The series covers the period 1990-2011. Data are available at 8 sites along a transect over an altitude range of 390 - 1850 meters (m) at approximately 67° North (N) in West Greenland. The surface mass balance gradient is on average 3.8 x 10^-3 m water equivalent/m, and the mean equilibrium line altitude is 1553 m above sea level (a.s.l). Only the lower 3 sites within 10 kilometers (km) of the margin experience a significant increasing trend in the ablation over the entire period.
