Projections of leaf area index in earth system models
The area of leaves in the plant canopy, measured as leaf area index (LAI), modulates key land-atmosphere interactions, including the exchange of energy, moisture, carbon dioxide...- publication PDF

Multi-model mean nitrogen and sulfur deposition from the Atmospheric...
We present multi-model global datasets of nitrogen and sulfate deposition covering time periods from 1850 to 2100, calculated within the Atmospheric Chemistry and Climate Model...- publication PDF

Parameterization and explicit modeling of cloud microphysics: Approaches,...
Cloud microphysical processes occur at the smallest end of scales among cloud-related processes and thus must be parameterized not only in large-scale global circulation models...- publication PDF

Co-benefits of global and regional greenhouse gas mitigation for US air...
Policies to mitigate greenhouse gas (GHG) emissions will not only slow climate change but can also have ancillary benefits of improved air quality. Here we examine the co-...- publication PDF

Hemispheric asymmetry of the vertical ion drifts at dawn observed by DMSP
Based on the measurements from Defense Meteorological Satellite Program (DMSP) F12, F13, and F15 satellites in 1995-2014, we report significant hemispheric asymmetries in...- publication PDF

Buffering of aerosol-cloud adjustments by coupling between radiative...
Aerosol-cloud interactions (ACI) in warm clouds are the primary source of uncertainty in effective radiative forcing (ERF) during the historical period and, by extension,...- publication PDF

Secondary organic aerosol formation from semi- and intermediate-volatility...
The role of aqueous multiphase chemistry in the formation of secondary organic aerosol (SOA) remains difficult to quantify. We investigate it here by testing the rapid formation...- publication PDF

Mars upper atmospheric responses to the 10 September 2017 solar flare: A...
We report the first global, time-dependent simulation of the Mars upper atmospheric responses to a realistic solar flare event, an X8.2 eruption on 10 September 2017. The Mars...- publication PDF

Analysis of the steady state available energy budget in the high-latitude...
We evaluate the budgets of available energy (AE) production, transport, and loss under steady state forcing of the high-latitude lower thermosphere during the southern summer...- publication PDF

Dynamical response of Mediterranean precipitation to greenhouse gases and aerosols
Atmospheric aerosols and greenhouse gases affect cloud properties, radiative balance and, thus, the hydrological cycle. Observations show that precipitation has decreased in the...- publication PDF
