SnowEx23 Snow Depth from Time-Lapse Imagery V001
Listed in NASA Earthdata CMR
The dataset comprises snow depth measurements extracted from snow poles in time-lapse images near Fairbanks, AK during the SnowEx 2022-2023 field campaign.
Description
Snow poles were 1.52 m (5 ft) vertical poles painted red with a 10.16-cm (4 in) yellow top. Collection occurred at 18 sites: 9 at the Bonanza Creek LTER and 9 at the Caribou-Poker Creeks Research Watershed.
At each site, three snow depth measurements were extracted, beginning at 11:00 AM daily. The time-lapse images are archived separately at NSIDC (<a href="doi.org/10.5067/UB3A44RTR6JD">SNEX23_TLI</a>).
