Richard Assmann had a particular interest in high altitude research of the Earth's atmosphere and was a pioneer in the field of aerology. With Léon Teisserenc de Bort

 (1855-1913), he is credited as co-discoverer of the stratosphere
The stratosphere is the second major layer of Earth's atmosphere, just above the troposphere, and below the mesosphere. It is stratified in temperature, with warmer layers higher up and cooler layers farther down. This is in contrast to the troposphere near the Earth's surface, which is cooler...

, as both men announced their discovery during the same time period in 1902.

From 1887 to 1892, with airship designer Rudolf Hans Bartsch von Sigsfeld (1861-1902), he developed a psychrometer for accurate measurement of atmospheric humidity
Humidity is a term for the amount of water vapor in the air, and can refer to any one of several measurements of humidity. Formally, humid air is not "moist air" but a mixture of water vapor and other constituents of air, and humidity is defined in terms of the water content of this mixture,...

 and temperature. This was the first instrument that was able to provide reliable temperature readings with high altitude balloons, as it was capable of shielding its thermometric elements from solar radiation. The technical implementation and production of this device took place in the factory of Rudolf Fuess (1838-1917).

From 1888 to 1899 he was a member of the Verein zur Förderung der Luftschifffahrt, where he organized scientific balloon ascents for atmospheric study. He is also remembered for popularizating the field of meteorology, and played a significant role in several scientific newspapers and magazines during his career. From 1884 until his death he published the popular monthly magazine Das Wetter (The Weather). In 1903 he was awarded the Buys Ballot Medal
