② Soot in the higher latitudes(纬度) of the Earth, where ice is more common, absorbs more of the sun’ s energy and warmth than an icy, white background. Dark-colored black carbon, or soot, absorbs sunlight, while lighter colored ice reflects sunlight. ③ Soot in areas with snow and...
, 2008b]. Additionally, quasi sun-aligned polar auroral filaments have been detected spanning the highly variable region poleward of the main oval, implying a relation to tail dynamics [Nichols and Clarke, 2009a]. Finally, UV data revealed the presence of bright isolated transient features ...
