ACTIVATE hopes to improve the understanding of aerosol dispersion and models, provide accurate data for aerosols’ characterization and ozone profiles, and establish knowledge of the relationships between aerosols and water. ACTIVATE’s science objectives are to quantify Na-CCN-Nd relationships and reduce uncertainty in model cloud droplet activation parameterizations, improve process-level understanding and model representation of factors governing cloud micro/macro-physical properties and how they couple with cloud effects on aerosol, plus assess advanced remote sensing capabilities for retrieving aerosol and cloud properties related to aerosol-cloud interactions. ACTIVATE utilizes the fixed-wing B-200 King Air to collect data. Data collected by ACTIVATE is highly relevant for meteorologists and environmental scientists looking to understand more about aerosol-cloud formations. Finally, ACTIVATE is a 5-year mission spanning from January 2019 to December 2023 and has used, and will continue to use, instruments such as the High Spectral Resolution Lidar-2 (HSRL-2), the Research Scanning Polarimeter (RSP), and the Diode Laser Hygrometer (DLH).展开更多

It will analyze the 21st century-coined phenomenon known as “Colony Collapse Disorder,” and will investigate research methods that have improved numbers within bee populations over the last two decades. Within this study, the impacts and interactions between the Colony Collapse Disorder phenomenon and various environmental factors will be discussed, as well as the interactions between the four main spheres of the Earth (i.e., the biosphere, lithosphere, atmosphere, and hydrosphere). In so doing, this study will evidence how and why bee populations are declining, why that decline affects each Earth sphere, as well as how this condition could create both loophole and contagion effects. Finally, this analysis will also briefly touch upon NASA’s increasing involvement with replenishing the world’s bee populations, the agency’s monitoring of CO<sub>2</sub> levels, various ecosystems, and other such relevant and ongoing research.展开更多
