Below-ground microbial communities increase carbon cycling due to fog drip and reduced evaporation caused by low-lying clouds.

Stratus cloud cover has numerous effects and benefits on soil, one of which is an increase in microbial activity. Stratus clouds are low to the ground, and so have more effect of ecosystems. Microbial communities are incredibly responsive to the fog drip and water pulses generated by increased stratus clouds, and their increased activity provides more carbon cycling for ecosystem productivity. These results are particularly notable during the summer when the ecosystem is under water stress.
