Arctic sea ice snow melt onset dates from the Advanced Horizontal Range Algorithm, version 5 (1979 - 2022)

Data

This data set includes one NetCDF (.nc) file containing the full set of annual Arctic sea ice melt onset dates and statistical summaries for the 1979 - 2022 period derived with the Advanced Horizontal Range Algorithm (AHRA) V5. The remaining .png files include browse images of each data layer contained within the primary NetCDF file.
