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
