Seasonal snow is an essential water resource in many mountains regions. Accurate snow depth observations are critical to assess water resources. Daily snow depth (SD) around 114 stations are used to analyse variations in snow cover days characteristics in Romania’s territory. This study investigates whenever these changes depend on elevation, underlying regional climatic features. Thus, the trends in snow cover days are analysed by using the non-parametric Man-Kendall test in trend detection. The Theil-Sen’s slope was also used to estimate the trend slope, expressing the magnitude (rate) of observed changes as days decade-1. Trend analysis was performed for each individual station within the boundaries of each climate region and each climate region and 500 m elevation band, to detect subsequent changes (increasing or decreasing), possible elevation dependencies and to capture country-wide spatial distribution patterns of change. Additionally, vertical profiles of trend slopes for each snow cover phenology parameter using a 100 m step were also used for evidence of elevation dependency across each climate region of the country. The results provide further evidence of a declining snow cover regime, with slight differentiations induced by the elevation. About 59% of stations experience significant (p<0.05) declines. The country-wide average change is ~0.33 days/decade, with a slightly higher decrease in the lowlands (with a maximum of ~0.74 days decade-1) than in the highlands ~0.25 days decade-1).
