In the summer of 1987 a weather station was placed on an old floodplain terrace about 200 m from the Sagavanirktok River. The site is vegetated by dwarf shrubs of Ericads and Betula. Initially the station was operational from late May/early June through August. In 1993 the station became year round. Any missing May through October average air temperature data were estimated using regressions with the Toolik Field Station weather station (68 degrees 38'N, 149 degrees 36'W). For a description of the site see Shaver, et al. 1996.
In addition to air temperature and wind speed which are reported here, global incoming radiation, photosynthetically active radiation (PAR), soil temperatures and wind direction were recorded. See the hourly data files.
