 Context examples 

The same kind of cycle takes place in Titan's troposphere — the weather-forming layer of Titan's atmosphere — but with methane instead of water.

(Scientists Find 'Impossible' Cloud on Titan, NASA)

Located at an altitude of about 100 to 130 miles (160 to 210 kilometers), the cloud is far above the methane rain clouds of Titan’s troposphere, or lowest region of the atmosphere.

(NASA Team Finds Noxious Ice Cloud on Saturn’s Moon Titan, NASA)

The findings indicate that WASP-18b has hot carbon monoxide in the stratosphere and cooler carbon monoxide in the layer of the atmosphere below, called the troposphere.

(WASP-18b Has Smothering Stratosphere Without Water, NASA)

The mechanism for forming these high-altitude clouds appears to be different from what happens in the troposphere.

(NASA Finds Methane Ice Cloud in Titan's Stratosphere, NASA)

The measurements showed that, during the transition from dry to wet season, transpired water becomes a significant moisture source for the atmosphere, and in particular for the middle troposphere, where the increasing water vapor provides the fuel needed to start the rainy season.

(New Study Shows the Amazon Makes Its Own Rainy Season, NASA)

A different condensation process takes place in the stratosphere — the region above the troposphere — at Titan's north and south winter poles.

(Scientists Find 'Impossible' Cloud on Titan, NASA)

Methane clouds were already known to exist in Titan's troposphere, the lowest layer of the atmosphere.

(NASA Finds Methane Ice Cloud in Titan's Stratosphere, NASA)

The newly identified cloud instead developed in the stratosphere, the layer above the troposphere.

(NASA Finds Methane Ice Cloud in Titan's Stratosphere, NASA)

Because the troposphere traps most of the moisture, stratospheric clouds require extreme cold.
