| Summary: | Arctic ecosystems are changing in response to arctic warming, which is proceeding more than twice as fast as the global average. The International Tundra Experiment (ITEX) was established in the early 1990s to understand the effects of warming and environmental variability on tundra vegetation properties and ecosystem function. The ITEX program has been extremely valuable for detection of changes in tundra plant and ecosystem responses to experimental warming and to background climate change across sites that span the major ecosystems of the Arctic. These files contain data representing the climate of ITEX sites in Utqiaġvik (formerly Barrow) and Atqasuk in a text comma delimited format. The data presented are hourly screen height temperature, precipitation, wind speed near the ground, and light intensity at Utqiaġvik and Atqasuk, Alaska.
