Explanation:

• Altitude of a particular air mass: As altitude increases, temperature generally decreases. Cooler air can hold less water vapor, so altitude affects water - vapor concentration.
• Seasonal time of year: Different seasons have different temperatures and weather patterns. For example, warmer seasons (like summer in many regions) can lead to more evaporation and potentially higher water - vapor concentrations in the air.
• Properties of Earth's surface below air mass: If the surface is a large body of water (ocean, lake) or wetland, there is more evaporation, increasing water - vapor concentration. Dry land surfaces like deserts have less evaporation.
• Properties of Earth's atmosphere above air mass do not directly affect the concentration of water vapor in the air mass in question. The water vapor in an air mass mainly comes from the surface below (through evaporation) and is affected by the local temperature (related to altitude and season) of that air mass.

Answer:

altitude of a particular air mass, seasonal time of year, properties of Earth's surface below air mass
