Importance of the Saharan heat low in controlling the North Atlantic free tropospheric humidity budget deduced from IASI delta D observations

Lacour, Jean-Lionel; Flamant, Cyrille; Risi, Camille; Clerbaux, Cathy; Coheur, Pierre-François (Copernicus GmbH, 2017-08-10)

The isotopic composition of water vapour in the North Atlantic free troposphere is investigated with Infrared Atmospheric Sounding Interferometer (IASI) measurements of the D ∕ H ratio (δD) above the ocean. We show that in the vicinity of West Africa, ...
Millennial-scale fluctuations in Saharan dust supply across the decline of the African Humid Period

Zielhofer, Christoph; von Suchodoletz, Hans; Fletcher, William J.; Schneider, Birgit; Dietze, Elisabeth; Schlegel, Michael; Schepanski, Kerstin; Weninger, Bernhard; Mischke, Steffen; Mikdad, Abdeslam (Elsevier BV, 2017-09)

The Sahara is the world's largest dust source with significant impacts on trans-Atlantic terrestrial and large-scale marine ecosystems. Contested views about a gradual or abrupt onset of Saharan aridity at the end of the African Humid Period dominate ...
