... Chemistry coursework practice Open book paper Different methods of collecting data to investigate the chemistry of the stratosphere The troposphere extends from 12km - 50km above the Earth's surface. Ozone is present from 15km - 35km. Many different techniques are used to investigate the stratosphere. Monitoring Measurements can be taken using the helium balloons. A 10 miles long cord is used to attach the balloon and the measuring device which can be reeled in and out to take measurements at different altitudes. Spectroscopic measurements can also be taken from the ground stations by looking upwards through the vertical column of the air. Laboratory measurements We need to know which species absorb solar radiation, the wavelength of the radiation absorbed and the strength of the radiation. It is also important to know which products are formed as a result of which reaction and the rate of the reaction, using the flash photolysis technique. In this, an intense laser
