Abstract
With increasing importance for forest management, National mountain meteorology observation system are under way of expansion. Yet, the location of the additional systems should be selected to contribute to reducing uncertainty imbedded in the data from the existing systems. Thus, this study conducted a spatio-temporal analysis for understanding the spatial distribution of the uncertainty in the meteorological data obtained from the existing systems. Time-series analysis on the maxima, minima, means and medians of temperature, relative humidity, wind speed and air pressure data was done to result in the uncertainty of each individual mountain meteorological factor. As a result, nine factors except maximum temperature, minimum relative humidity, wind speed average, maximum wind speed, maximum air pressure, and air pressure minimum commonly show higher uncertainty around Baekdu-Daegan region. Based on the uncertainty map, additional systems are better to select their location among the high uncertainty areas.
