Heliocentric Distance and Solar Activity Dependence of Sustained Quasi-radial Interplanetary Magnetic Field Occurrence

The Astrophysical Journal, 2023
Planets close to their stars experience an interplanetary magnetic field (IMF) that is dominantly quasi-radial. Our solar system serves as a laboratory to study how the occurrence of quasi-radial IMF varies away from the star and under different stellar ...

CVaR-based Flight Energy Risk Assessment for Multirotor UAVs using a Deep Energy Model [PDF]

, 2021
Energy management is a critical aspect of risk assessment for Uncrewed Aerial Vehicle (UAV) flights, as a depleted battery during a flight brings almost guaranteed vehicle damage and a high risk of human injuries or property damage. Predicting the amount of energy a flight will consume is challenging as routing, weather, obstacles, and other factors ...

Interconnected hydrologic extreme drivers and impacts depicted by remote sensing data assimilation

Scientific Reports, 2023
Hydrologic extremes often involve a complex interplay of several processes. For example, flood events can have a cascade of impacts, such as saturated soils and suppressed vegetation growth.

Implications of carbon monoxide bias for methane lifetime and atmospheric composition in chemistry climate models [PDF]

Atmospheric Chemistry and Physics, 2015
A low bias in carbon monoxide (CO) at northern high and mid-latitudes is a common feature of chemistry climate models (CCMs) that may indicate or contribute to a high bias in simulated OH and corresponding low bias in methane lifetime. We use simulations
