[MSD35-02] High resolution multi-angular polarimeter for the cloud and aerosol monitoring and the comprehension of physical processes
Keywords:Polarization, Cloud, Aerosol, Imaging
In next 20 years, the impacts of the climate change are expected to be clearly perceivable in many aspects of geophysical observations while the human activities experience an unprecedented transformation. Developed nations will continue on the path of decarbonization whereas emerging economies in Asia and Africa will industrialize and urbanize. Such remarkable changes of human activities consequently bring a change in the emission pattern of anthropogenic greenhouse gases and aerosol particles which will have a profound impact on the public health, urban pollution, and future projection of climate. There is, therefore, pressed social and scientific demands for the global measurement of changing emission, pollution, and climate variables that reflect the socioeconomic landscape in next 20 years.
In this regard, we propose an wide-swath high-resolution multi-viewing polarimeter with following overarching objectives: (1) the quantification of aerosol particles that changes year after year in response to the climate change and socioeconomic factors, (2) the estimation of cloud-top altitude and aerosol plume height, and (3) the investigation of cloud microphysical process, including the cloud-aerosol interaction. The proposed sensor profit from the heritage of successful GCOM-C/SGLI sensor, with significant improvements in spatial resolution and accuracy of polarimetric measurements. The new continuous multi-viewing capability and high spatial resolution enable us to quantify the aerosols over populated cities and steep mountains, as well as to measure the altitude of cloud and aerosol plumes. The wide field-of-view inherited from SGLI makes the frequent global coverage possible and leads to the responsive analysis of massive aerosol emitting events such as forest fire and volcanic eruptions. In addition, the combination of multi-viewing capability and high spatial resolution results in frequent observation of cloud sides that benefit cloud microphysical process studies.
