Cloud and Aerosol Monsoonal Processes - Philippines Experiment (ROSES 2016)
Atmospheric composition changes affect air quality, weather, climate, and critical constituents, such as ozone. Atmosphere-biosphere exchange links terrestrial and oceanic pools within the carbon cycle and other biogeochemical cycles. Solar radiation affects atmospheric chemistry and is thus a critical factor in atmospheric composition. Atmospheric composition is central to Earth system dynamics, since the atmosphere integrates surface emissions globally on time scales from weeks to years and couples several environmental issues. NASA’s research for furthering our understanding of atmospheric composition is geared to providing an improved prognostic capability for such issues (e.g., the recovery of stratospheric ozone and its impacts on surface ultraviolet radiation, the evolution of greenhouse gases and their impacts on climate, and the evolution of tropospheric ozone and aerosols and their impacts on climate and air quality). Toward this end, research within the Atmospheric Composition Focus Area addresses the following science questions:
• How is atmospheric composition changing?
• What trends in atmospheric constituents and solar radiation are driving global climate?
• How do atmospheric trace constituents respond to and affect global environmental change?
• What are the effects of global atmospheric chemical and climate changes on regional air quality?
• How will future changes in atmospheric composition affect ozone, climate, and global air quality?
The Radiation Sciences Program is soliciting proposals for participation in an airborne campaign to be conducted in the vicinity of the Philippines during July, August, and into early September of 2018 to investigate aerosol particle, cloud, meteorology/climate interactions. A single comprehensively instrumented research aircraft is required to accomplish this research. In this airborne campaign, the NASA P-3B will provide observations from near surface to ~9.7 km.
Aircraft measurements of atmospheric cloud and aerosol particle properties, radiation, and meteorology parameters provide a comprehensive suite of observations to understand these processes during the focused experiment period. They are also useful for calibration and validation of the longer-term observations of Earth observing satellite sensors and the retrieved data products generated from those observations. In particular, these measurements will be useful in the calibration and validation of the more mature A-Train and Terra satellites and S-NPP and GPM observatories. The measurements made during this campaign will also be useful in the planning of future satellite missions, especially the Aerosol, Cloud, and Ecosystems (ACE) mission.
