Temperature measurements of first-year sea ice in the sea of Okhotsk using an airborne infrared radiometer
Brightness temperature of the Okhotsk coastal sea was measured by an airborne infrared radiometer off Hokkaido, Japan on February 16,1984. The infrared brightness temperatures were around 270 K for open water, 264 to 266 K for level fast ice and 268 K for thin level ice and young gray ice, when the...
