Observed 20th century desert dust variability: impact on climate and biogeochemistry [PDF]

Atmospheric Chemistry and Physics, 2010
Desert dust perturbs climate by directly and indirectly interacting with incoming solar and outgoing long wave radiation, thereby changing precipitation and temperature, in addition to modifying ocean and land biogeochemistry.

Deferred Cooling System for Desert Climates

Advances in Mechanical Engineering, 2020
The paper presents the design of a novel heat rejection system suitable for desert climates where daytime temperatures are typically high, nighttime cooling through sky radiation exchange is highly effective, and freshwater is scarce. Desert climates also feature high solar energy intensities during daytime, which can be exploited to power ...
