We did atmospheric measurements at two different locations: Tähtvere Park and Ülejõe Park
during the GLOBE Estonia Learning Expedition in Tartu, Estonia on 8 August 2023. Our
main goal was to find out how the data of various weather stations differs from our
measurements. We were curious if the observed two parks would have different results in
atmospheric indicators. We also wanted to find out how long it would take for atmospheric
indicators to show any notable changes.
Our hypotheses were:
● The results from the weather stations will show some variance, but generally, the
indicators will be quite similar.
● The data from the two parks will be different.
● The indicators will not change notably in half an hour.
We discovered that all the weather stations, we compared, had some variances in their
atmospheric data. This could be because of the different locations of the stations, the different
equipment which was used to make the measurements and so on. We also realised that half an
hour is enough time for atmospheric indicators to change notably and we did in fact see
differences between the data from the two parks.
Studying the atmosphere is important because it helps us predict the weather and see how the
climate is changing, which in turn makes it easier to protect the climate. Comparing and
researching different weather stations and equipment, used to measure the atmosphere, helps
us study local weather variability as well as find flaws and make sure that all the
measurements are accurate.
