Errors in wind direction data at Dome Fuji Station, and corrections
Some kinds of error in surface wind direction data at Dome Fuji Station observed by the 38th Japanese Antarctic Research Expedition (JARE-38) in 1997 are reported. The most serious error is that the wind direction data was shifted toward azimuths of 45-, 135-, 225- and 315-degrees. However. data cor...
