3 Objects that carry instruments into the stratosphere to measure atmospheric conditions

Explanation:

Weather balloons are objects that carries instruments into the stratosphere to measure atmospheric conditions.

They are very important weather measuring device that helps meteorologists in their fore casts.

These balloons are specially designed for high altitudes. They carry very sensitive devices that are very useful in collecting information about temperature, precipitation, pressure e.t.c
