SnowEx23 Apr23 Spectrometer Snow Surface Reflectance and Albedo, Version 1 V001

This data set contains a comprehensive set of field-based measurements of snow surface reflectance and broadband snow albedo collected during the NASA SnowEx 2023 field campaign in interior Alaska. Data were acquired in April and May 2023 across three study sites near Fairbanks, Alaska, selected to represent the dominant boreal landcover types: closed-canopy forests, recently and historically burned forests, and open meadows. Together, these environments capture the heterogeneity of snow–vegetation interactions that influence snow albedo in high-latitude ecosystems.
