Samples were collected over the forested mountains of central Mongolia, southwest of the capital Ulaanbaatar. These flights were conducted in collaboration with the Mongolian Hydrometeorological Research Institute. Sample collection at ULB started in March 2004, but the site was discontinued in March 2009 because of funding cuts.
