Insights on the climate of Bhutan from a new daily 1 km gridded data set for temperature and precipitation

Gridded climatological data derived for Bhutan from internationally available sets either come at a very low spatial resolution, or do not provide daily data, contain few in situ measurements. We present newly developed high-resolution (1 km) gridded set covering the years 1996–2019 precipitation and maximum minimum temperature (BhutanClim). As input, we used quality-controlled homogenized up to 67 weather stations National Center Hydrology Meteorology of Bhutan. The interpolation consists non-linear vertical profile combined with an inverse-distance residuals. uses non-Euclidian distance that takes elevation differences between grid cells topographic obstacles into account. coverage allows calculation climate indicators need such as frost days days. new climatology benefits use local measurements shows plausible small-scale patterns.
