Background: Historical Temperature Records
Explanation of how temperature records have been kept throughout history
Temperature records have been an essential part of meteorological studies since the late 18th century. Initially, temperature readings were taken at meteorological stations, which were usually located in cities or towns where population density was high. These records, known as instrumental records, were obtained using various instruments such as thermometers, hygrometers, and barometers. The instrumental records provide accurate and precise temperature data, making them crucial for climate research. However, their availability is limited to the periods when the stations were in operation and when the records have been preserved.
Description of the earliest temperature records and their limitations
The earliest temperature records date back to the 17th century. One of the oldest known temperature series is the Central England Temperature Record, which began in 1659. This record was compiled from various sources, including diaries, parish records, and correspondence. Another early temperature series is the Greenland Ice Core Project (GRIP) record, which extends back to 1600 AThese proxy records, derived from tree rings, ice cores, and historical documents, provide valuable temperature information for periods before the establishment of instrumental recording stations. However, they come with limitations such as uncertainties in calibration and interpretation, which affect their accuracy and precision. Nevertheless, these records are crucial for understanding long-term climate variability and trends.
