Environmental concerns, climate change, water and food security, as well as urban air pollution. All these problems are interconnected, but are studied separately. Because of this, it is impossible to get a full picture of the state of our planet. This was decided to be corrected by Professor Markku Kulmala.
He wrote an article calling for the creation of a global observatory of the Earth, referring to the conclusions of many years of experience in collecting environmental information. He created the station SMEAR II (Station for the Measurement of Ecosystem-Atmospheric Relations) in the forests of Finland, showing how one can obtain a generalized set of calculations on the environment. Kulmal believes that creating such a large-scale observatory will require approximately 1,000 well-equipped ground stations. They will monitor the environment around the world and receive a continuous stream of data. Then this information can be combined with information from satellite observation, laboratory experiments and computer models.
The creation of such an observatory will take 10-15 years. Estimated costs are $ 11.8–20 million per station, which is comparable to the creation of one Large Hadron Collider. But the professor insists on the need for construction to cover problems in scale and integrity.
