Pallas-Sammaltunturi, GAW Station, Finland [PAL]
Most of the stations at Pallas that are part of the global station Pallas-Sodankylä are located within the Pallas-Yllästunturi National Park, inside the northern boreal forest zone. The Pallas area is free of large local and regional pollution sources with the nearest town, Muonio with some 2500 inhabitants, being 19 km to the west. The second-nearest town, Kittilä, with 6000 inhabitants, is 46 km to the south-east. The main station, Sammaltunturi (67°58'N 24°07'E, 560 m a.s.l.) is on top of a fjeld (a subarctic hill), ca. 300 m above the surrounding area and some 100 m above the tree line. The vegetation on the fjeld top consists mainly of low vascular plants, moss, and lichen. The region is hilly with the highest elevations of 600-800 m within 3-6 km from the station. The sectors 180°-330° and 100-130° are very open. Also part of this global station is the observatory Sodankylä (67°22'N 26°38'E, 178 m a.s.l.).
