Description
Radiation transmittance through three ice types was measured in the 400-600 nm range at Silver Lake, Michigan and Whitefish Point on Lake Superior. The dataset includes surface and under-ice sensor readings, date, time, ice thickness, water depth, sensor distance, and location. It is produced by NASA and available in BIN, ISO, and HTML formats.
Use Cases
Modeling photosynthetically active radiation (PAR) attenuation through different freshwater ice types.
Analyzing the relationship between ice thickness and light transmittance to the water column.
Comparing optical properties of clear ice, refrozen slush ice, and brash ice.
Studying spatial and temporal variability of under-ice light regimes in northern lakes.
Strengths
Measures three distinct ice types: clear ice, refrozen slush ice, and brash ice.
Provides paired surface and under-ice sensor readings for calculating transmittance ratios.
Includes precise physical measurements like ice thickness, water depth, and sensor distance.
Limitations
Conflicting last updated dates: 2026-03 13 (datagov) vs. 1978-12-31 (nasa_earthdata).
