Stockholm Meteorological Station

Understanding, tracking, and predicting the weather is something that humanity has been obsessed with for millennia. However, it wasn't until the 18th century that science was able to develop accurate tools and data storage methods to understand weather patterns.

Around this time, meteorological institutions began to pop up across the globe along with the construction of weather stations. Sweden's first weather station was designed by Pehr Wilhelm Wargentin, the secretary of the Swedish Royal Society and director of the Stockholm Observatory in 1754. 

Wargentin tweaked and perfected various methods utilized to take weather measurements, which eventually became so precise his measurements were recognized as the average temperature of the region. 

The station has been updated over the centuries, but its core function never changed. It's seen as the oldest continuously running weather station that has not been moved. 

Nowadays, observations of temperature, precipitation, snow depth, air pressure, humidity, wind, visibility, cloud, and weather conditions are carried out three times a day.
