DOC release of Laohugou Glacier No. 12 was 192 kg km−2
, of which 43.2 % could be decomposed and return to atmosphere as CO2
within 28 days, producing positive feedback in the warming process and influencing downstream ecosystems. Radiative forcing of snow pit DOC was calculated to be 0.43 W m−2
, accounting for about 10 % of the radiative forcing caused by BC. Therefore, DOC is also a light-absorbing agent in glacierized regions, influencing the albedo of glacier surface and glacier melting.
