Chemical forecasting in support of field missions

Chemical transport forecasts have become essential tools for tropospheric aircraft missions over the last few years. The use of these state-of-the-art models to define mission objectives, flight-planning, as well as to interpret observations allows to directly test atmospheric processes in a context where flight hours are often limited.

We have designed an interactive web interface to visualize and disseminate GEOS-Chem and GEOS-5 model forecasts in support of five major field missions: ITCT2K2 (April-May 2002), INTEX-A (July-August 2004), INTEX-B (March-April 2006), ARCTAS (spring and summer 2008), and HIPPO (2009-2010).

On-going field missions

NOMADSS: During the summer of 2013, we participated in the NOMADSS (Nitrogen, Oxidants, Mercury and Aerosol Distributions, Sources and Sinks) NSF experiment, which was part of the Southeast Atmosphere Study. This field campaign used the C-130 aircraft and was based in Tennessee for a 6 week period: June 1- July 17 2013. GEOS-5 chemical forecasts: . We are currently working on analyzing observations of reactive mercury obtained during NOMADSS.

WINTER: In 2015 we will participate in the WINTER (Wintertime INvestigation of Transport, Emissions, and Reactivity) NSF experiment. This field campaign will use the C-130 aircraft flying out of the Baltimore/Washington D.C. area for 6 weeks (February 1 - March 15, 2015). We will investigate the emissions, chemistry and fate of pollutants during winter. Planning animations: here
