Seasonal variations of Quercus pubescens isoprene emissions from an in natura forest under drought stress and sensitivity to future climate change in the Mediterranean area [PDF]

open access: yesBiogeosciences, 2018
At a local level, biogenic isoprene emissions can greatly affect the air quality of urban areas surrounded by large vegetation sources, such as in the Mediterranean region.

A comprehensive benchmarking system for evaluating global vegetation models [PDF]

open access: yesBiogeosciences, 2013
We present a benchmark system for global vegetation models. This system provides a quantitative evaluation of multiple simulated vegetation properties, including primary production; seasonal net ecosystem production; vegetation cover; composition and ...

Estimating the near-surface permafrost-carbon feedback on global warming [PDF]

open access: yesBiogeosciences, 2012
Thawing of permafrost and the associated release of carbon constitutes a positive feedback in the climate system, elevating the effect of anthropogenic GHG emissions on global-mean temperatures.

Inferring past land use-induced changes in surface albedo from satellite observations: a useful tool to evaluate model simulations [PDF]

open access: yesBiogeosciences, 2013
Regional cooling resulting from increases in surface albedo has been identified in several studies as the main biogeophysical effect of past land use-induced land cover changes (LCC) on climate.

Recommendations for reporting "black carbon" measurements [PDF]

open access: yesAtmospheric Chemistry and Physics, 2013
Although black carbon (BC) is one of the key atmospheric particulate components driving climate change and air quality, there is no agreement on the terminology that considers all aspects of specific properties, definitions, measurement methods, and ...

Stratospheric ozone trends for 1985–2018: sensitivity to recent large variability [PDF]

open access: yesAtmospheric Chemistry and Physics, 2019
The Montreal Protocol, and its subsequent amendments, has successfully prevented catastrophic losses of stratospheric ozone, and signs of recovery are now evident.

Quantifying the variability of the annular modes: reanalysis uncertainty vs. sampling uncertainty [PDF]

open access: yesAtmospheric Chemistry and Physics, 2018
The annular modes characterize the dominant variability of the extratropical circulation in each hemisphere, quantifying vacillations in the position of the tropospheric jet streams and the strength of the stratospheric polar vortices.
