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).

Here here a link to our current interactive web interface HIPPO which displays results from the GEOS-5 chemical forecasts:

Currently we are working on 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:
