atmospheric sciences graduate students receive nasa finesst project fundingli-wei vivian chao and nancy okeudo have both been awarded research project fundingjul 10 2020li-wei vivian chao atmospheric sciences phd studentnancy okeudo atmospheric sciences phd studentli-wei vivian chao and nancy okeudo both phd students in the department of atmospheric sciences at texas a&m university have received funding from the future investigators in nasa earth and space science and technology (finesst) program chaos research proposal aimed to leverage clouds and the earths radiant energy system (ceres) satellite measurements to develop an improved energy balance framework and constrain climate sensitivity by combining estimates of how the controlling factors for each component change as the climate warms how much warming the world is going to experience in the future has always been an essential question chao said the traditional way scientists have approached the problem has several known issues that result in the uncertainty of future temperature changes the goal of my research is to revisit the concept of planetary energy balance by analyzing satellite measurements of the radiative flux from clouds and the non-cloud components of the atmosphere the result of the research will hopefully improve the ability to predict future climate the project is titled developing an improved energy balance framework using ceres planetary energy balance observations and dr andrew dessler professor of atmospheric sciences is chaos advisor and will service as principal investigator of the project climate change is basically an energy balance problem dessler said you have energy coming in from the sun balanced by heat radiated back to space as we add carbon dioxide to the atmosphere it throws these terms out of balance leading to climate change i think vivians research will help us understand some of the fine points of this process and hopefully resolve some long-standing problems okeudos research centers on light scattering by dust aerosol particles and relevant downstream applications to satellite remote sensing my research focus is on improving the physical geometric optics method (pgom) an approximate method that calculates the single-scattering properties of moderate to large-sized particles okeudo said the problem is that pgom is inaccurate in calculating the single-scattering properties of moderate-sized particles because there are some effects (edge effect surface wave interactions) that are not included in pgom as a result my goal in my research project is to add the edge effect corrections to pgom improving pgom will improve our understanding in the role aerosol particles have in the earths radiation budget she said the funded project is titled a study of the optical properties of non-spherical particles with the physical geometric optics method and okeudos advisor dr ping yang atmospheric sciences professor and geosciences associate dean for research will serve as principal investigator i am very proud of nancys achievements yang said her finesst project is directed towards elevating our knowledge about the optical properties of dust aerosols in particular the proposed comparisons between theoretical simulations and satellite observations will aim at defining an optimal dust optical property model therefore successful completion of the proposed work would lead to realistic optical properties of dust particles which would benefit ground-based and spaceborne remote sensing of dust aerosol properties the finesst program reviewed a total of 789 proposals with nasas earth science division receiving 341 of those and selecting 62 for award of which okeudo's and chaos were two by leslie lee 09
