Radiative and Thermodynamic Responses to Uncertainty in Aerosol Extinction Profiles
Jan 18, 2016       
Aerosol radiative effects are of great importance for climate simulations over South Asia. For quantifying aerosol direct radiative effect, aerosol optical depth (AOD) and single scattering albedo (SSA) are often compared with observations. These comparisons have revealed large AOD underestimation and SSA overestimation in models over this region. Aerosol vertical distributions have received less scrutiny [...]

A New Model for Liquid Water Absorption
Jan 08, 2016       
Liquid water path (LWP) is a critical measurement for a wide range of atmospheric studies, as the amount of liquid in a cloud is critical to understanding many cloud processes. For example, the radiative impact of the cloud (in both the longwave and shortwave portions of the spectrum) depends heavily on the LWP. Thus, [...]

The Role of Shallow Cloud Moistening in MJO and Non-MJO Convective Events over the ARM Manus Si
Dec 11, 2015       
Moistening by shallow clouds has been assumed to be partially responsible for the observed increase in low-level moisture leading to convective peaks of the Madden-Julian Oscillation (MJO). In this study, we move beyond the argument for the moistening role of shallow clouds in the MJO that is simply based on simultaneous increases in both low-level [...]

Evaluation of Subgrid-Scale Hydrometeor Transport Using a High-Resolution CRM
Dec 11, 2015       
Clouds moderate the climate system through direct impact on surface hydrology, as gatekeepers for the sun’s energy-in/energy-out flux, and by stabilizing the atmosphere through vertical redistribution of heat and moisture. Turbulent convective clouds and storms are especially efficient at moving moisture and heat in the atmosphere. But because the structure of these clouds is not [...]
