Color, odor.
Tempature and humidity are almost always the 2 traits given, even if the terms are vague, such a as a warm moist air mass or a cold dry air mass. The terms are in reference to the air mass in an area before the new one being described.

Temperature and moisture
There are more than two properties of air and all of them are important. Properties of an air mass include pressure, density, and temperature.
Temperature and amount of water vapor.
Color, odor.
Volume and mass are two universal properties of matter.
Mass and volume are two extensive properties.
Matter has mass and occupies space. So, mass and volume are the two major properties of matter.
Tempature and humidity are almost always the 2 traits given, even if the terms are vague, such a as a warm moist air mass or a cold dry air mass. The terms are in reference to the air mass in an area before the new one being described.
Mass and Density
The colors and lines in the spectrum of a star indicate the elements that make up the star.
Mass and volume are the two.
