Meteorological Calendar 2027 - Historical meteorological measuring instruments

The Meteorological Calendar 2027 would like to take you on a brief journey through time and introduce you to some historical measuring instruments.

In East Asia, there were already rain gauges in the 15th century that were very similar to today’s devices.The physical relationships between meteorological parameters were only discovered in recent centuries. Building up on this, a new generation of measuring instruments emerged, which in return offered more insights into atmospheric processes. However, significant developments in the field of measurement technology took place in recent. Many tried-and-tested instruments have been, and continue to be, replaced by electronic sensors. You may even own some of these instruments featured in this calendar, such as a minimum-maximum thermometer.

The photographs on the front pages of the calendar capture the beauty and variety of what can otherwise described rather superficially by the term ‘weather’.
