Biogenic volatile organic compounds (BVOCs) affect the climate and air quality, while their emission from terrestrial vegetation is affected by drought in a way that is not well characterized. Our study reveals that the instantaneous intraday changes in meteorological conditions serve as a better proxy for drought-related variations in BVOCs emission rate than the absolute values of the meteorological parameters, advancing our understanding of BVOCs emission effects under climate change.

A primary sink of air pollutants is dry deposition. Dry deposition estimates differ across the models used to simulate atmospheric chemistry. Here, we introduce an effort to examine dry deposition schemes from atmospheric chemistry models. We provide our approach’s rationale, document the schemes, and describe datasets used to drive and evaluate the schemes. We also launch the analysis of results by evaluating against observations and identifying the processes leading to model–model differences.

The ocean heat content (OHC) estimated using two eddying hindcast simulations, OFES1 and OFES2, was compared from 1960 to 2016, with observation-based results as a reference. Marked differences were found, especially in the Atlantic Ocean. These were related to the differences in the net surface heating, heat advection, and vertical heat diffusion. These documented differences may help the community better understand and use these quasi-global high-resolution datasets for their own purposes.
