Validation, trend analysis & bias reduction through satellite fusion of the cloud-top height record from terra MODIS & MISR
Modeled clouds contribute the largest uncertainty in modeled responses to climate change. While significant uncertainties exist in predictions of the complicated pathways in which cloud amounts (CA), cloud-top heights (CTH) and cloud opacity respond to warmer temperatures, there is robust agreement …

Factors Governing Cloud Growth and Entrainment Rates in Shallow Cumulus and Cumulus Congestus During GoAmazon 2014/2015
Shallow cumulus and cumulus congestus clouds play an important role in the large-scale tropical circulation by mixing heat and moisture vertically and preconditioning the environment for deeper convection. Different representations of these shallow clouds also account for much of the spread in …

Using high-resolution modelling to improve the parameterisation of convection in a climate model
… influencing the development of moist convective clouds. Through this work a 1D cloud-model was derived from first principles to represent the vertical profile of individual convective clouds. A microphysics framework was implemented to ensure identical behaviour in LES and cloud-model integration …

An Investigation of the Relationship Between Low Cloud Cover And Lower Tropospheric Stability Using MISR
Marine boundary layer clouds account for a significant amount of uncertainty in future climate change projections from general circulation models (GCMs). To reduce the uncertainty of the role of clouds in GCMs, improved cloud parameterizations and evaluations of these parameterizations are often …

Feasibility of using cloud top altimetry for estimating tropical cyclone intensity estimation
This project explores whether cloud top altimetry can be used as an accurate and reliable means of estimating the intensity of tropical cyclones. Professor Kerry A. Emanuel developed the theory that is under investigation. His theory aims to calculate the peak surface wind speed in hurricanes using …

The influence of longwave cloud-top cooling on marine stratocumulus cloud transitions
… the turbulent structure within the stratocumulus-topped boundary layer in the Southeast Pacific is simulated using near-LES model framework and sounding data from the Variability of American Monsoon Systems (VAMOS) Ocean–Cloud–Atmosphere–Land Study Regional Experiment (VOCALS-REx) as the initial …

Characteristics of Yellow Sea Fog Under Varying Aerosol Conditions
… (OMI) aboard on the EOS-Aura satellite, and the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) satellite which observe aerosol, ozone and cloud properties. These observations show a clear influence of aerosol loading over the Yellow Sea region which can have an impact …

Characterization of Tropical Clouds Using Multi-Satellite Observations
<p>Clouds an important component of the earth-climate system and play a critical role in affecting energy and water cycle of the planet. In particular, tropical convective clouds account for the majority of the precipitation that fall on the Earth's surface. Multiple active satellite missions in …

On the nature of the atmospheric cloud radiative effect and its impact on tropical convection
Tropical high clouds have been shown to converge radiant energy within the atmosphere. We term this phenomenon the Atmospheric Cloud Radiative Effect (ACRE). The addition of energy unequally in space and time has profound effects on tropical convection. In this thesis, we show that the extra …

The calculation of cloud parameters from AVHRR data
… that is reflected from and emitted by a clear or cloudy terrestrial atmosphere. Calculations are performed in order to estimate the radiation exitant to space in the visible, the near visible, and the two infrared windows at approximately 4 μm and 11 μm. The NOAA-9 satellite Advanced Very High …

Airborne lidar observations of tropospheric arctic clouds
… sensitive to climate changes. The influence of clouds on the radiation budget is substantial, but difficult to quantify and parameterize in models. In the framework of the PhD, elastic backscatter and depolarization lidar observations of Arctic clouds were performed during the international …
