However, it was the first time NASA had put out an open call for citizen scientists to record the sky above their heads. The first calima recorded with GLOBE Clouds wasn’t the worst Saharan dust storms have to offer. The danger of dust storms comes less from the spectacle or the distance traveled but rather from how they pollute the air. An uptick in Valley Fever in the Southwest US has been credited to dust storms, and the spread of meningitis in North Africa has long been linked with Saharan dust events. The thing is, dust storms don’t usually hit Godzilla levels, and they didn’t use to send Saharan dust to Arkansas, either.
