    partial pressure

    Explanation:

    The partial pressure of a gas in a mixture of gases is the individual pressure that the gas would exert if it occupied the same volume as the mixture at the same temperature.

    Air is a mixture of gases. The atmosphere is composed of this mixture of gases each exerting its own unique partial pressure.

    Hence measuring the individual pressures of carbon dioxide, oxygen and nitrogen in the atmosphere means that the scientist seeks to determine the partial pressures of each of the components of air.
