WebTransmittances through the ponded ice were roughly an order of magnitude larger than the bare ice . The peak transmittance was 0.46 at 425 nm for ponded ice and 0.034 at 520 nm for bare ice. In both bare and ponded ice cases, transmittances decreased sharply beyond 700 nm owing to increased absorption by the ice. WebOct 31, 2015 · Bare, melting ice had peak transmittance in the range of 0.05–0.3. Ponded ice had peak transmittance from 0.25 to about 0.73. Peak values typically occurred somewhere between wavelength 470 and 500 nm. As was seen for the spectral albedo, ponded ice spectral transmittance shows more variability than bare ice transmittance.
