Lämpötilasarjat

Lämpötilasarjat, often translated as temperature series or temperature records, refer to historical collections of temperature measurements taken over time at a specific location. These data sets are crucial for understanding climate change, identifying trends, and making climate projections. They typically include daily, monthly, or annual average temperatures, as well as minimum and maximum temperatures.

The collection of temperature series began in the 17th century with early meteorological observations. Over time, the methods and instruments for measurement have become more standardized and accurate, leading to increasingly reliable long-term records. Modern temperature series are compiled from a variety of sources, including land-based weather stations, ocean buoys, and satellite data.

Analyzing temperature series involves identifying patterns such as warming or cooling trends, seasonal variations, and anomalies. Statistical methods are employed to distinguish natural climate variability from human-induced climate change. Global temperature series, such as those maintained by NASA GISS, NOAA NCDC, and the Met Office Hadley Centre/CRU, show a clear and consistent warming trend over the past century.

These data are vital for scientific research, informing policy decisions, and raising public awareness about the state of the climate. The integrity and accessibility of temperature series are therefore of paramount importance for climate science and action.
