et al., 2013). Based on satellite altimetry, the trend in absolute sea
level in the North Sea was about 1-3 mm/yr in 1992-2014, depending on location (EEA, 2017).
In the Baltic, the mean sea level rose 1.5 mm/yr in the 20th century (Nerheim et al., 2017). The
absolute sea level rise for the Scandinavian coast of the Baltic in period 1891-1990 was found to
be 1.8 mm/yr (O. Vestøl, 2006). In 1992

the principalmethods have not changed much over the years, theamount of field work has varied. In the first 15 yearsthe monitoring programme at Storbreen was com-prehensive, often three or more snow density pits
were dug, snow depth was measured at about 600points and ablation was measured on 30 stakes
evenly distri uted on the glacier (Liestøl 1967).Based on experience of the snow pattern, the ob-

Many QA guidelines exist such as Middlemis (2000) and
Van Waveren et al. (1999). The HarmoniQuA project (Schol-
ten et al., 2007; Refsgaard et al., 2005a) has developed a com-
prehensive set of QA guidelines for multiple modelling
domains combined with a supporting software tool, MoST
