Highlights•Maize yields in sub-Sahara Africa are low due to low fertilizer input.•This creates
a yield gap (difference between potential and actual maize yield).•Closing yield gaps will …

A global assessment of precipitation chemistry and deposition has been carried out under
the direction of the World Meteorological Organization (WMO) Global Atmosphere Watch …

Debate concerning the environmental impact of human arrival in Australia has continued for
more than a century. Here we review the evidence for human impact and the mechanisms …

Vegetation fires emit large amounts of nitrogen compounds in the atmosphere, including
ammonia (NH 3). These emissions are still subject to large uncertainties. In this study, we …

We exploit 6 years of measurements from the Infrared Atmospheric Sounding Interferometer
(IASI)/MetOp‐A instrument to identify seasonal patterns and interannual variability of …

A method is developed to estimate global NO2 and SO2 dry deposition fluxes at high spatial
resolution (0.1°× 0.1°) using satellite measurements from the Ozone Monitoring Instrument …

In the framework of the IDAF (IGAC/DEBITS/AFrica) international program, this study aims to
study the chemical composition of precipitation and associated wet deposition at the rural …

Territorial or resting behaviour of large herbivores can cause strong local deposits of dung,
in different places than where they graze. Additionally, dung beetles and other …

This work is part of the IDAF program (IGAC-DEBITS-AFRICA) and is based on the long-term
monitoring of gas concentrations (1998–2007) established at seven remote sites …

Land use specific deposition velocities of atmospheric trace gases and aerosols—
particularly of reactive nitrogen compounds—are a fundamental input variable for a variety …
