This is a selectable map of statistics for the 2023 Alaska NWC Airborne Gamma Survey through April 25th, 2023.
The fractions on points indicate the Snow Water Equivalent rank out of the number of years worth of Airborne
Gamma Snow Surveys. For example, 2/18 indicates the second highest SWE value out of 18 years of surveys.
Values represented in gray (39.37") are unknown values where no Gamma radiation was returned and the
sensor maxed out. Ranks for these locations were based on the historical data and nearby flight lines
and airborne analyst review.
