In-Plant Biochemistry Governs High Altitude Fine Particles over the Amazon
Combining aircraft measurements and regional modeling allowed researchers to identify the role of in-plant biochemistry in secondary organic aerosol formation.
Freeze-Thaw Cycles Alter Soil Structure in Thawing Permafrost
Soil pores are reorganized when newly thawed permafrost soils experience freeze-thaw cycling.
Smaller-Scale Models Better Represent Pouring Rain over the Amazon
State-of-the-art numerical models can better simulate the convective clouds that produce most of the Amazon’s wet season rainfall.
Record Regional Rainfall Linked to COVID-Induced Aerosol Emissions Reduction
The COVID-19 pandemic massively disrupted human activities, which caused additional turmoil through regional record rainfall and floods.
Amazon Rainforest Foliage Gases Affect the Earth’s Atmosphere
PNNL researchers have uncovered a plant-derived process that leads to the formation of aerosol particles over the Amazon rainforest and potentially other forested parts of the world.
Generating Robust Precipitation Projections from Climate Models
The climate models best at simulating current precipitation and its drivers show more consensus in projecting future precipitation.
