atmospheric chemical composition and variability have been studied extensively. However, this is not the case for the Pyrenees. Few measurement campaigns have been carried out, with the aim of documenting the influence of meteorological conditions on the atmospheric composition at the Pic du Midi (PDM) observatory: Atmospheric Pollution in the Pyrenees (PAP; Ezcurra et al. 2013 ), Pic 2005 ( Gheusi et al. 2011 ), and Pic 2010 ( Gheusi et al. 2016 ). Ezcurra et al. (2013) present experimental data from

cooling path with prescribed initial evaporation and condensation conditions. Such models have been used to assess the impact of equilibrium and kinetic fractionation processes on the snowfall isotopic composition ( Merlivat and Jouzel 1979 ; Jouzel and Merlivat 1984 ). The second-order isotopic parameter deuterium excess d = δ D − 8 × δ 18 O ( Dansgaard 1964 ) is expected to be highly sensitive to kinetic effects occurring either during evaporation at the ocean surface or during atmospheric

1. Introduction An accurate quantification of the effects of anthropogenic emissions on the ozone layer is a key step toward making accurate predictions of the future ozone evolution. Assessing the ozone response to anthropogenic forcings is also a step toward improved understanding of the coupling between atmospheric composition and climate ( Isaksen et al. 2009 ). There is robust modeling evidence suggesting that anthropogenic greenhouse gases (GHGs), via their influences on stratospheric

appropriately chosen sites are an ideal archive for reconstructing past atmospheric dust aerosol loading, transport, and chemical composition prior to the instrumental record. Ice cores provide high-resolution, well-preserved, multiparameter archives of the atmospheric signature from remote regions, including information about past temperature, precipitation, atmospheric circulation, and atmospheric chemistry. The glaciated, high-elevation mountain regions in Asia are located downwind or in the vicinity of

advance for both atmosphere and ocean science disciplines. The NRC placed GEO-CAPE within the second tier of missions, recommended for launch within the 2013–16 time frame. In addition to providing information for addressing scientific questions, the NRC advised that increasing the societal benefits of Earth science research should be a high priority for federal science agencies and policy makers. In August 2008, two GEO-CAPE Science Working Groups (SWGs)—one from the atmospheric composition observing
