Description :
In this study, the AA. collected climate data at a range of different scales for the Abisko region, Northern Sweden, and evaluated both the scale mismatch and the coupling among these datasets. First, a comparison of the large-scale weather station measurements and gridded climate reanalysis (ERA-40) data is used to define regional climatology in the Swedish sub-Arctic and obtain the mesoscale temperature lapse rates. Second, combined with temperature measurements obtained from transects set among complex terrain, key microclimatic characteristics of the temperature distribution are identified, showing few temperature inversions. The results were used to build a topoclimate model at 50-m resolution. Model validation is conducted using further fieldwork measurements from different seasons.
