lämpötilallisilla

lämpötilallisilla is a Finnish term that literally means “temperature lists” but has come to denote structured records of temperature measurements kept over a period of time. Such lists are used by meteorologists, climate researchers, and agricultural planners to treat temperature data as data sets rather than casual observations. They are distinct from weather diaries in that they adhere to a predetermined sampling schedule and statistical methodology.

The concept arose with the establishment of the Finnish Meteorological Institute in the early 20th century. The institute introduced standardized temperature logbooks, which were soon dubbed lämpötilallisilla in Finnish-language scientific literature. The primary goal was to create comparable datasets across different weather stations. Hence, the lists contained entries for every hour of the day, and each entry recorded both the ambient temperature and the measurement accuracy.

In the 1970s, the advent of computerized loggers automated the process, so that temperature values were transferred to the lists automatically. Modern usage now refers to digital databases rather than physical booklets, yet the name lämpötilallisilla survived as a historical label. Analysts extract the lists to produce long‑term climate trends, to evaluate the effectiveness of energy‑conservation strategies, and to develop forecasts for agriculture and public health.

In popular Finnish culture, the term occasionally appears in literature and journalism when describing sections of statistical reports. The phrase carries a tone of precision and systematic rigor, reflecting the scientific heritage behind temperature monitoring.
