Dust Over Argentina

Dust plumes blew out from Argentina on November 3, 2016. This natural-color image was acquired that day by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite.

South America is no stranger to dust storms. In Argentina, an abundance of fine sediment has caused many events in the last few years large enough to be recorded by satellites. Here, the dust blows east toward the Atlantic Ocean.

Though a frequent occurrence, this November’s dust comes after a particularly dry year in parts of South America. Nearby Paraguay faced severe drought along its Pilcomayo River. Meanwhile, neighboring Brazil is in the midst of its most severe drought in 35 years, according to Relief Web.
