Short summary
In this study, we found, due to contribution of carbonates, previously reported BC concentration in atmosphere of the Himalayas and Tibetan Plateau (HTP) were overestimated by around 39–52 %. Meanwhile, we found BC deposition of lake cores overestimated the atmospheric deposition of BC in the HTP; BC depositions of glacier region reflected actual values of 17.9 ± 5.3 mg m−2 a−1. The above results are critical for studying atmospheric distribution and chemical transport of BC in and around the HTP.
