Air, snow and ground temperature observations at three sites near Chokurdakh, Russia in 2015

Our research area is located near Chokurdakh (71N, 148E) in Northeastern Siberia, Russia, about 150 km inland from the Arctic sea coast along the Indigirka River. Three study sites were selected for air, snow and ground temperature monitorings at the height of +1.50, +0.30, +0.20, +0.10, -0.01, -0.05, -0.10, -0.20, -0.30, -0.40, -0.50, -0.75, -1.00, -1.50, -2.00, -3.00, -4.00, -5.00, -5.50, -7.00 and -10.0m, respectively; Boydom is the northernmost tundra site among our study sites along the Indigirka River, Kodac is situated in a forest-tundra landscape 8 km south of Boydom, and Verkhny Khatistakh is a larch-dominated forest near a northern end of tree line.

我们的研究区域位于俄罗斯东西伯利亚东北部的乔库尔达赫（Chokurdakh，北纬71°，东经148°）附近，沿因迪吉尔卡河距离北冰洋海岸约150公里内陆处。三个研究站点分别对空气、积雪及地面温度进行监测，监测高度为+1.50、+0.30、+0.20、+0.10、-0.01、-0.05、-0.10、-0.20、-0.30、-0.40、-0.50、-0.75、-1.00、-1.50、-2.00、-3.00、-4.00、-5.00、-5.50、-7.00及-10.0米；Boydom是因迪吉尔卡河沿线研究站点中最北端的苔原（tundra）站点，Kodac位于Boydom以南8公里的森林苔原（forest-tundra）景观区，而Verkhny Khatistakh则是林线北端附近以落叶松为主的森林站点。
