AEROSOL OBSERVATIONS IN THE SIBERIAN ARCTIC
Atmospheric concentrations of total particulate mass (TPM) and aerosol chemical species were measured at three sites in the Siberian Arctic; Tiksi, Norilsk and Yakutsk. Continuous samplings of aerosols were carried out from August 1993 in Norilsk and Yakutsk, and from August 1994 in Tiksi. Tiksi is...

Atmospheric concentrations of total particulate mass (TPM) and aerosol chemical species were measured at three sites in the Siberian Arctic; Tiksi, Norilsk and Yakutsk. Continuous samplings of aerosols were carried out from August 1993 in Norilsk and Yakutsk, and from August 1994 in Tiksi. Tiksi is located on the coast of the Laptev Sea connecting to the Arctic Ocean. Norilsk is located at the base of the Taimyr Peninsula, which is the largest single sulfur dioxide emission source in the world. Yakutsk is situated on the middle reaches of the Lena river.
