Studies of the atmosphere first received technical support in 1912. Equipment to measure temperature and pressure was invented in Germany. But the question was how to raise it high into the air. In 1921, Russian engineers suggested using planes. The special equipment was put on planes that made regular flights. Thanks to this, scientists got a lot of new information about the structure of the atmosphere. Nowadays scientists use modern flying laboratories to study the structure of clouds at different levels. Unlike the first planes, these laboratories can work in any weather and are able to predict climate changes.
