Shrivastava Gives Keynote at Atmospheric Optics Meeting
Shrivastava invited to present a keynote talk on secondary organic aerosols at Air & Waste Management Association conference.
Wildfires Trigger Violent Storms with Large Hail and Lightning
Research reveals how heat and aerosols from wildfires initiate and invigorate severe storms.
More Urbanization Could Mean More Rain for Cities
A new study shows that urban heat island effects and increased urban aerosols can spur intense rainfall.
Sulfur Dioxide Emission Height Reveals Uncertainty in Radiative Forcing Across Earth System Models
The Emissions Model Intercomparison Project examined how selected emissions-related properties affected results in 11 global chemistry and Earth-system models.
Emulating Interactions Between Atmospheric Particles and Light with Machine Learning
Randomly constructed neural networks can learn how to represent light interacting with atmospheric aerosols accurately at a low computational cost and improve climate modeling capabilities.
State of Stress Assessment Tool
The State of Stress Assessment Tool (SOSAT) is a set of routines that take in information about a geologic carbon storage reservoir and generates a probability distribution for the state of stress in the reservoir before and during injection. As part of this, the tool reports the estimated probability of a critically-oriented fault becoming activated as a result of the injection. The tool also allows a storage site operator to evaluate the likely value of different types of characterization on the knowledge of the geomechanical conditions and probability of induced seismicity.
SYSTEM AND METHOD OF PRECONCENTRATING ANALYTES IN A MICROFLUIDIC DEVICE
Electrokinetic injection is used almost exclusively for microchip electrophoresis. We describe a new approach, based on pneumatic valving, that overcomes the limitations of electrokinetic injection. A detailed description is in the attached file.
Spatial Heterogeneity of Clouds Impacts Rain Initiation in Global Models
The rate of conversion of cloud droplets to precipitation, known as the autoconversion rate, remains a major source of uncertainty in characterizing aerosol’s cloud lifetime effects and precipitation in global and regional models.
E4D
E4D is a 3D geophysical modeling and inversion program designed for subsurface imaging and monitoring using static and time-lapse electrical resistivity tomography (ERT), spectral induced polarization (SIP) and travel-time tomography data.
