True color corrected reflectance image of dust blowing off the coast of Namibia and South Africa on June 27, 2022. This image was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS), aboard the Terra satellite. The dust blowing out into the South Atlantic Ocean is caused by berg winds. These are hot, dry winds that blow down from inland mountains and plateaus and agitate dust and fine sediments as they pass over the coastal plain.
