Daily data on snowfall and snow cover observed at the Nagaoka Institute of Snow and Ice Studies in the 1992/93 winter season are reported. These data include the following items : weather condition, depth and water equivalent of snow cover, and depth, cumulative depth, water equivalent and density of newly fallen snow. The observation was carried out in the same way as Kobayashi et al. (1990), for example, with the automatic snow depth meter by an infrared technique for snow depth and the metal wafer for water equivalent of snow cover. It has been warm for seven winter seasons since the 1988/89 winter, and we had little snow in the 1992/93 winter as well. The maximum snow depth was 50cm recorded on March 2 in 1993 and the cumulative depth of newly fallen snow was 420cm. The former maximum value of snow depth was the second smallest record, since the snow cover observation at our institute was started in December, 1964.
