Thaw Depth and Vegetation Radiance Measurements, Happy Valley, AK, 1994
https://data.eol.ucar.edu/dataset/106.ARCSS103

Summary
This data set contains measurements for permafrost active layer thaw depth and
vegetation reflectance (red and near-infrared bandwidths) at the Happy Valley
Flux Study Site in northern Alaska during the summer of 1994. Sampling was
conducted in a 1000-m square grid pattern, with sample points spaced 100 m
apart. Median values for thaw depths were determined from five replicate
measurements using a thaw probe. Vegetation radiance values are averages of
five measurements collected from an area approximately 5 square meters at each
grid point. Radiometric measurements were collected with Exotech-100BX,
4-channel radiometers fit with spectral filters corresponding to the
SPOT/HRV-XS satellite bandwidths.
