Annual Maximum Summer Snowline Dataset for Six Glaciers in the Canadian Arctic (2013–2024)

This dataset provides annual maximum summer snowline altitude estimates from 2013 to 2024 for six glaciers across the Canadian Arctic and High Arctic: Highway, BylotD20s, Coronation, Fountain, Turner, and White glaciers. Snowline positions were derived from multispectral satellite imagery using two complementary methods implemented in Python via glacier-snow-cover-mapping-for-ANP-and-SNP: Snow‑Elevation Histogram Analysis (SEHA):An automated machine learning-assisted approach that estimates the Equilibrium Line Altitude (ELA) by analyzing the histogram of reflectance-derived snow cover and glacier surface elevation. Output columns: datetime_SLA_SEHA, SLA_SEHA_m, SLA_SEHA_AAR, SLA_SEHA_SCA_m2 Bin-based Delineation (SLA_bin method):A binned Accumulation Area Ratio (AAR) analysis method using pixel-based snow classification and terrain binning. Output columns: datetime_SLA, SLA_m, SLA_AAR, SLA_SCA_m2 Both methods use data from Landsat 8/9 and Sentinel-2 satellites.
