The greater the level of extrapolation the more error prone the model results may become. A simplified version of a complex process oriented RAINS Lake Model (RLM) was developed by regression methods to quantify these extrapolation errors. RLM variables that explain more than 1% of the variation in the model output (pH of 1980) were selected and calibrated to the measured pH distribution in 1980 in the southern region of Finland from 1920 to 1980. An iterative procedure was then used to select the minimum number of variables which best represented the behavior of the RLM. The results show that extreme regional characteristics may necessitate adaptation of a simplified model that has been calibrated in a less extreme regional context. date: 1988-01 date_type: published official_url: http://www.osti.gov/scitech/biblio/6997418 creators_browse_id: 1954 creators_browse_id: 1896 full_text_status: none pres_type: paper event_title: Annual Meeting of Air Pollution Control Association event_location: Dallas, TX, USA event_dates: 19-24 June 1988 event_type: conference refereed: FALSE coversheets_dirty: FALSE fp7_type: info:eu-repo/semantics/conferenceObject citation: Hettelingh, J.-P. & Gardner, R.H.
