“Albedo dome”: a method for measuring spectral flux-reflectance in a laboratory for media with long optical paths
(Applied Optics, 2015)
A method is presented for accurate measurement of spectral flux-reflectance (albedo) in a laboratory, for media with long optical path lengths, such as snow and ice. The approach uses an acrylic hemispheric dome, which, when placed over the surface being studied, serves two functions: (i) it creates an overcast “sky” to ...
The spectral albedo of sea ice and salt crusts on the tropical ocean of Snowball Earth: II. Optical modeling
(Journal of Geophysical Research: Oceans, 2016)
During the Snowball Earth events of the Neoproterozoic, tropical regions of the ocean could have developed a precipitated salt lag deposit left behind by sublimating sea ice. The major salt would have been hydrohalite, NaCl•2H2O. The crystals in such a deposit can be small and highly scattering, resulting in an allwave albedo ...
