Sources of atmospheric mercury in the tropics: continuous observations at a coastal site in Suriname [PDF]
Atmospheric Chemistry and Physics, 2012 Mercury measurements at a coastal site in Nieuw Nickerie (5°56' N, 56°59' W), Suriname, provide the only continuous records of atmospheric mercury in the tropics. Here we evaluate observations of total gaseous mercury (TGM) during 2007.

Metastability of Northern Hemisphere Teleconnection Modes
Journal of the Atmospheric Sciences, 2015 Abstract This study applies a finite-element, bounded-variation, vector autoregressive method to assess midtropospheric flow regimes characterized by regime switches between metastable states. The flow is assessed in reanalysis data from three different reanalysis sets assimilating surface data only; surface and upper-air data; and ocean,

No trends in spring and autumn phenology during the global warming hiatus
Nature Communications, 2019 A global warming hiatus occurred during 1998 and 2012 but its effects on phenology are unclear. Here the authors examine the trends in spring and autumn phenology in the northern hemisphere and the effects of the warming hiatus and show that phenology ...

Mid-Holocene Intertropical Convergence Zone migration: connection with Hadley cell dynamics and impacts on terrestrial hydroclimate [PDF]
Climate of the PastThis study investigates the multiple changes of the Hadley cell (HC) in response to the northward migration of the Intertropical Convergence Zone (ITCZ) and their combined influence on the terrestrial hydrological cycle during the mid-Holocene, using ...
