Abstract To establish a climatic basis for mapping plant production potential of the mountain areas, meteorological measurements were carried out at several selected sites in Øystre Slidre in the Valdres region. The stations were situated between 550 meters and 1330 meters above sea level, and the sites were chosen to investigate the importance of surface slope/direction and soil conditions (peatland vs. adjacent upland) on soil and air temperature. In addition to the usual meteorological factors (temperature, humidity, precipitation, wind velocity and direction), pan evaporation was measured at five sites (550–1170 m a.s.l.) and global radiation at one site (1000 m a.s.l.). The paper gives a brief description of the local climate at each site based on measurements mainly performed during the years 1975–1978. The different sites are compared with respect to growth climate, with emphasis to temperature and potential evapotranspiration. Special weight has been given to general climatic trends and results which may be of general value at the expense of detailed data tables. Such tables, being of interest for further agricultural planning in the specific area, will be presented elsewhere. Key Words: climatemountain areatemperaturepotential evapotranspiration
