Researchers said frequent future rocket launches 'could have a significant cumulative effect on the Earth's climate'.
They set out to assess the potential impact of a rocket launch on atmospheric pollution by investigating the heat and mass transfer and rapid mixing of the combustion byproducts for altitudes up to 41 miles (67 km) into the atmosphere.
The team at the University of Nicosia in Cyprus modelled the exhaust gases and developing plume at several altitudes along a typical trajectory of a standard present-day rocket.
The rise of low-cost space transportation led by SpaceX, Virgin Galactic and Blue Origin is increasing the amount of engine exhaust pollution in Earth's atmosphere, a study has warned
Troposphere is where humans live and weather exists, the lowest layer stretching up to about six miles.
Stratosphere extends up to about 40 miles and contains much of the ozone in the atmosphere.
Mesosphere sits just above the stratosphere where temperature decreases with height, reaching -130F.
Thermosphere is where temperatures begin to increase with height, caused by the absorption of UV and X-rays.
Exosphere starts at 310 miles and contains oxygen and hydrogen atoms, but in very low numbers.
Magnetosphere features charged particles along magnetic field
