SILICON PHOTODIODES
Definition
- SILICON PHOTODIODES: With this instrumentation, radiation transmittance (ratio of transmitted to incident radiation) through clear ice, refrozen slush ice and brash ice, from ice surface to ice water interface in 400 to 600 nanometer range (photosynthetically active range), was measured at two freshwater lakes. Data taken with this included surface and under-ice sensor readings, date and time of observation, solar angle, ice thickness, water depth, distance of under-ice sensor from ice bottom surface, and site number/location.
