  • Cavity ringdown spectroscopy measurements of the infrared water vapor continuum 

    Reproduced from Cormier, John G., Roman Ciurylo, and James R. Drummond. 2002. "Cavity ringdown spectroscopy measurements of the infrared water vapor continuum." Journal of Chemical Physics 116(3): 1030-1034, with the permission of AIP Publishing.
    The measurements of the water vapor continuum were analyzed using infrared cavity ringdown spectroscopy (CRDS) at frequencies of 931.002, 944.195 and 969.104 cm-1. The experiments uses a continuous-wave CO2 laser and an ...

  • Infrared water vapor continuum absorption at atmospheric temperatures 

    Reproduced from Cormier, John G., Joseph T. Hodges, and James R. Drummond. 2005. "Infrared water vapor continuum absorption at atmospheric temperatures." Journal of Chemical Physics 122(11), with the permission of AIP Publishing.
    We have used a continuous-wave carbon dioxide laser in a single-mode realization of cavity ring-down spectroscopy to measure absorption coefficients of water vapor at 944 cm-1 for several temperatures in the range 270-315 ...

  • Origin of lapse rate changes in the upper tropical troposphere 

    Folkins, Ian. 2002. "Origin of lapse rate changes in the upper tropical troposphere." Journal of the Atmospheric Sciences 59(5): 992-1005.
    Vertical motions in clouds arise from a variety of thermodynamic processes, including latent heat release, evaporative cooling, melting, and cloud radiative heating. In the Tropics, the net upward vertical mass flux from ...

  • The vertical structure of tropical convection and its impact on the budgets of water vapor and ozone 

    Folkins, Ian, and Randall V. Martin. 2005. "The vertical structure of tropical convection and its impact on the budgets of water vapor and ozone." Journal of the Atmospheric Sciences 62(5): 1560-1573. doi:10.1175/JAS3407.1
    Convective clouds in the Tropics that penetrate the boundary layer inversion preferentially detrain into a shallow outflow layer (2-5 km) or a deep outflow layer (10-17 km). The properties of these layers are diagnosed ...
