sademäärille

The term sademäärille, derived from the Finnish words sade (rain) and määrille (means or amounts), refers to the quantified total of precipitation received over a specific period or location. In meteorological practice, sademäärille is expressed in millimetres (mm) or centimetres (cm) and is an essential metric for assessing weather conditions, forecasting, and climate studies. Measurement is typically conducted with automatic rain gauges that collect data at predefined intervals, and the summed values represent the sademäärille for that interval.

Sademäärille data are used in diverse fields such as hydrology, where rainfall totals influence flood risk assessment and water resource management. In agriculture, farmers rely on accurate sademäärille records to determine irrigation needs and crop yield predictions. Climate scientists analyze long‑term sademäärille records to detect trends in precipitation patterns, which may be linked to global warming or regional climatic shifts.

National meteorological agencies in Finland, including the Finnish Meteorological Institute, maintain extensive networks of gauge stations that provide daily and weekly sademäärille summaries. These datasets are often uploaded to international databases, such as the World Meteorological Organization’s Global Historical Climatology Network, to enable cross‑national comparisons. In addition to ground observations, satellite precipitation products supplement sademäärille estimates in regions with sparse gauge coverage.

Understanding and correctly interpreting sademäärille is crucial for policy makers, emergency services, and environmental researchers. Accurate records help in issuing timely weather warnings, managing water supplies, and conducting environmental impact assessments, thereby underscoring the importance of reliable precipitation measurement and reporting.
