Abstract. While substantial progress has been made to improve our understanding of biogenic isoprene emissions under unstressed conditions, large uncertainties remain with respect stressed conditions. Here, we use the US Drought Monitor (USDM) as a weekly drought severity index and tropospheric columns formaldehyde (HCHO), key product oxidation, retrieved from Ozone Monitoring Instrument (OMI) ...

The 2012 drought was one of the most extensive drought events in half a century, resulting in over USD 12 billion in economic loss in the United States and substantial indirect impacts on global food security and commodity prices. An important feature of the 2012 drought was rapid development and intensification in late spring/early summer, a critical time for crop development and investment pl...

Abstract Drought events may reduce growth and survival of conifer trees. The effects the intensity timing drought on resilience, including reductions during recovery after drought, remain, however, highly uncertain. Growth resilience 20 species to 11 dry years was compared in a common garden experiment. We assessed (a) relationships among resistance, (b) impacts different dimensions (intensity,...

Drought reduces plant productivity, induces widespread plant mortality and limits the geographic distribution of plant species1–7. As climates warm and precipitation patterns shift in the future8,9, understanding the distribution of the diversity of plant drought tolerance is central to predicting future ecosystem function and resilience to climate change10–12. These questions are especially pr...

Drought is a normal, recurring feature of climate. The characteristics of this hazard, along with its far-reaching impacts, make its effects on society, economy, and environment difficult to identify and quantify. A national drought watch system has been recommended as a necessary component of drought assessment and management. The National Drought Mitigation Center, in collaboration with other...

Recent drought events in the United States and the magnitude of drought losses indicate the continuing vulnerability of the country to drought. Until recently, drought management in many states, including Nebraska, has been largely response oriented with little or no attention to mitigation and preparedness. In 1998, Nebraska began to revise its drought plan in order to place more emphasis on m...
