Regional Chemical Modeling: Projects

Southeast mountains
Great Smoky Mountains National Park

SENEX 2013, Southeast US. The goal of SENEX 2013 is to study the interactions between natural and anthropogenic emissions in the southeast at the nexus of the air quality and climate change. Scientists will quantify the emissions of greenhouse gases and aerosol, and investigate the roles played by anthropogenic and natural emissions in the formation of ozone and aerosol in the atmosphere. This airborne study involves the NOAA WP-3D aircraft, forecast modeling and surface monitoring networks. More info...

E&E UBWOS, Horsepool, Utah, 2012 and 2013. The Energy and Environment - Uintah Basin Winter Ozone Study (E&E UBWOS) was designed to study the causes of high wintertime ozone observed in the Uintah Basin. Scientists constructed a ground site of instruments to study sources of VOCs, NOx and particles, ozone formation chemistry in areas of enhanced UV radiation from snow cover, unique radical sources (HONO, CH2O, ClNO2) and the role of transport.

DC3, Salina, Kansas, 2012. The Deep Convective Clouds & Chemistry (DC3) experiment investigates the impact of deep, midlatitude continental convective clouds, including their dynamical, physical, and lightning processes, on upper tropospheric composition and chemistry. Airborne measurements taken from the NASA DC-8 in July 2012 provide in situ observations to characterize the convective storm inflow and provide remote sensing to aid in flight planning and column characterization.

CalNex 2010, Southern California. The goal of the California Research at the Nexus of Air Quality and Climate Change (CalNex) 2010 program is to study the important issues at the nexus of the air quality and climate change problems, and to provide scientific information regarding the trade-offs faced by decision makers when addressing these two inter-related issues. The NOAA WP-3D aircraft, the R/V Atlantis ship, and several ground sites were involved in this project. Comprehensive data analysis followed the completion of this project in July 2010. More info...

ARCPAC, Fairbanks, Alaska, 2008. As part of the International Polar Year of 2008, NOAA engaged in an airborne field measurement campaign targeted at improving understanding climate-relevant processes. This effort was focused on direct measurements of properties and processes that can be used to reduce uncertainty in radiation and climate models. The measurements were made in the Alaskan Arctic to closely coordinate with remote-sensing and in situ observations planned for aircraft and ground sites in the vicinity of Barrow, Alaska.

TexAQS, Houston, Texas, 2006. This intensive field study focused on providing a better understanding of the sources and atmospheric processes responsible for the formation and distribution of ozone and aerosols in the atmosphere and the influence that these species have on the radiative forcing of climate regionally and globally, as well as their impact on human health and regional haze. The study area included Texas and the northwestern Gulf of Mexico. This project used the NOAA WP-3D and the R/V Ronald H. Brown as research platforms. More info...
