Abstract
In many fields including agroclimatology, pedology, plant introduction, environmental health and agricultural transfer, detection of areas of similar climate is of significant interest. Numerical methods including cluster analysis, similarity measures, and other techniques were used to compare climatic data from Islandian meteorological stations to classify them according to similar homoclimate. Using Euclidean distance and City-block (Manhattan) distance, data from Iceland, Finland, Sweden, Norway, and Alaska state of the USA were analyzed to reveal homoclime. One of the conclusions from the study is that Iceland has a similar climate to Alaska and Norway. Climate change is already affecting agriculture, with effects unevenly distributed across the world. These changes will undoubtedly lead to a reconsideration of the question of allocation of appropriate agricultural crops to given areas and evaluation of bioclimatic resources in territories with similar climate. Results from this study are related to the territory of Iceland, but the approach to classify meteorological stations according to similar homoclimate and reveal homoclime in selected territories is applicable everywhere in the world.

Summary
Introduction cultural transfer, detection of areas of similar climate is of significant interest. Future climate change will likely negatively affect crop production in low latitude countries, while positive trends are evident in some northern regions (Porter et al 2014). Numerical methods including cluster analysis, similarity measures, and other techniques were used to compare climatic data from Iceland stations in order to classify them according to similar homoclimate.
