    • Adding four-dimensional data assimilation by analysis nudging to the Model for Prediction Across Scales – Atmosphere 

      Bullock, Orren Russell, Jr.; Foroutan, Hosein; Gilliam, Robert C.; Herwehe, Jerold A. (Copernicus Publications, 2018-07-16)
      The Model for Prediction Across Scales – Atmosphere (MPAS-A) has been modified to allow fourdimensional data assimilation (FDDA) by the nudging of temperature, humidity, and wind toward target values predefined on the ...
    • Coupling of organic and inorganic aerosol systems and the effect on gas-particle partitioning in the southeastern US 

      Pye, Havala O. T.; Zuend, Andreas; Fry, Juliane L.; Isaacman-VanWertz, Gabriel; Capps, Shannon L.; Appel, K. Wyat; Foroutan, Hosein; Xu, Lu; Ng, Nga L.; Goldstein, Allen H. (European Geophysical Union, 2018-01-12)
      Several models were used to describe the partitioning of ammonia, water, and organic compounds between the gas and particle phases for conditions in the southeastern US during summer 2013. Existing equilibrium models and ...
    • Improving the simulation of convective dust storms in regional-to-global models 

      Foroutan, Hosein; Pleim, Jonathan E. (AGU Publications, 2017-09-05)
      Convective dust storms have significant impacts on atmospheric conditions and air quality and are a major source of dust uplift in summertime. However, regional-to-global models generally do not accurately simulate these ...
    • Intercomparison of Small Unmanned Aircraft System (sUAS) Measurements for Atmospheric Science during the LAPSE-RATE Campaign 

      Barbieri, Lindsay; Kral, Stephan T.; Bailey, Sean C. C.; Frazier, Amy E.; Jacob, Jamey D.; Reuder, Joachim; Brus, David; Chilson, Phillip B.; Crick, Christopher; Detweiler, Carrick; Doddi, Abhiram; Elston, Jack; Foroutan, Hosein; González-Rocha, Javier; Greene, Brian R.; Guzman, Marcelo I.; Houston, Adam L.; Islam, Ashraful; Kemppinen, Osku; Lawrence, Dale; Pillar-Little, Elizabeth A.; Ross, Shane D.; Sama, Michael P.; Schmale, David G. III; Schuyler, Travis J.; Shankar, Ajay; Smith, Suzanne W.; Waugh, Sean; Dixon, Cory; Borenstein, Steve; de Boer, Gijs (MDPI, 2019-05-10)
      Small unmanned aircraft systems (sUAS) are rapidly transforming atmospheric research. With the advancement of the development and application of these systems, improving knowledge of best practices for accurate measurement ...
    • Pollution Transport Patterns Obtained Through Generalized Lagrangian Coherent Structures 

      Nolan, Peter J.; Foroutan, Hosein; Ross, Shane D. (MDPI, 2020-02-06)
      Identifying atmospheric transport pathways is important to understand the effects of pollutants on weather, climate, and human health. The atmospheric wind field is variable in space and time and contains complex patterns ...
