SnowEx23 Apr23 IOP Snow Surface Imagery V001
Listed in NASA Earthdata CMR
This data set contains 54 photographs of snow surfaces collected during the NASA SnowEx23 field campaign near Fairbanks, Alaska.
Description
Photos were acquired in April and May 2023 at three study sites that represent a range of landcover conditions, including intact boreal forest, recently and historically burned forest, and open meadows. Snow surface photographs were collected concurrently with ground-based hyperspectral spectrometer measurements, snow surface samples, and alongside coincident observations from NEON towers, uncrewed aerial vehicles (UAVs), NASA’s AVIRIS-NG airborne sensor, and hyperspectral satellite instruments.
Each photo was taken at the same location as field snow surface reflectance and albedo measurements and snow surface samples, providing visual context for interpreting spectral variability.
