Welcome to STELA

Dr. Udaysankar S. Nair's research group, STudies in Ecosystem, Land and Atmosphere (STELA) at Earth System Studies Center (ESSC), University of Alabama in Huntsville (UAH), studies land, atmosphere and ecosystem processes with emphasis on the impact of land use change on atmospheric processes.



  • Impact of land use change on atmospheric circulation, cloud and precipitation formation
  • Atmospheric transport and dispersion
  • Impact of aerosols on nocturnal boundary layer development
  • Atmospheric mercury pollution


  • Radiative forcing due to land use change
  • Global radiative energy budget: Role land surace albedo
  • Agent-based modeling of deforestation by the ancient Maya


  • Biogeography of cloud forests
  • Role of environmental characteristics in determining species distribution in montane regions


  • Field Campaigns
  • Satellite Remote Sensing
  • Numerical Modeling
