Influence of Varieties and Organic Fertilizer in the Elaboration of a New Poplar-Straw Pellet and Its Emissions in a Domestic Boiler by Sergio Paniagua, Alba Prado-Guerra, Ana Isabel Neto, Teresa Nunes, Luís Tarelho, Célia Alves, Luis Fernando Calvo

“…Pollutants resulting from domestic combustion would have harmful effects on public health, causing disturbances in the atmosphere chemistry and the climate. In this work, the emissions from the combustion of pellets made of 80% poplar (organically fertilized) and 20% cereal straw (<i>Triticum aestivum</i>) have been analysed. …”

Development of the GEOS-5 atmospheric general circulation model: evolution from MERRA to MERRA2 by A. Molod, L. Takacs, M. Suarez, J. Bacmeister

“…The GEOS-5 AGCM presented here is the model used as part of the GMAO MERRA2 reanalysis, global mesoscale simulations at 10 km resolution through 1.5 km resolution, the real-time numerical weather prediction system, and for atmosphere-only, coupled ocean-atmosphere and coupled atmosphere-chemistry simulations. <br><br> The seasonal mean climate of the MERRA2 version of the GEOS-5 AGCM represents a substantial improvement over the simulated climate of the MERRA version at all resolutions and for all applications. …”
