Patent number: 11226323Abstract: A computer implemented method, computer system, and computer program product are provided for air-pollution emission source monitoring. To determine the air-pollution emission of a monitored area, location data and air pollution data are taken from sensor stations positioned along a boundary of the monitored area. The macroscale atmospheric data of a region, where the monitored area is located, is also received. A boundary pollutant distribution can be estimated based on the location data and the air pollution data. Horizontal diffusion and vertical diffusion of the monitored area can be estimated based on the boundary pollutant distribution and the macroscale atmospheric data. To determine an accurate amount of pollution contribution caused by a monitored area, a calculation based on the boundary pollutant distribution, the horizontal diffusion, and the vertical diffusion can be used.Type: GrantFiled: April 27, 2018Date of Patent: January 18, 2022Assignee: International Business Machines CorporationInventors: Yu Tao Ba, Gang Zhou, Lingyun Wang, Wei Zhao, Ming Xie, Ke Xu Zou, Xiao Guang Rui

Patent number: 10746714Abstract: A processor-implemented method receives a plurality of pollution measurement data, a plurality of geodetic data, and a plurality of meteorological data associated with a geographical area. The processor-implemented method generates a grid of the geographical area, whereby the generated grid virtually divides the geographical area into a plurality of cells. The processor-implemented method associates the received plurality of measurement data, the received plurality of geodetic data, and the received plurality of meteorological data with a cell in the generated grid. The processor-implemented method determines a pollutant contribution value of the cell based on the pollution measurement data associated with the cell and a physical contribution of a plurality of pollutants. The processor-implemented method identifies the pollution source based on a paired comparison of the plurality of cells and displays the location on the geographical area associated with the identified pollution source.Type: GrantFiled: June 16, 2017Date of Patent: August 18, 2020Assignee: International Business Machines CorporationInventors: Yu Tao Ba, Ming Xie, Lingyun Wang, Ke Xu Zou, Wenchen Cheng, Gang Zhou

Patent number: 10627380Abstract: The disclosure involves multi-source data assimilation. According to an embodiment, first data associated with an indication of environmental quality in a first region is obtained, and second data associated with an indication of environmental quality in a second region is obtained. The first data is of a higher quality than the second data according to a predetermined criterion. The second data is calibrated according to a relationship between the first and second data in an overlap of the first and second regions. Third data associated with an indication of environmental quality in a third region is determined based on the first data and the calibrated second data, wherein the third region comprises at least the first and second regions.Type: GrantFiled: February 8, 2017Date of Patent: April 21, 2020Assignee: International Business Machines CorporationInventors: Yu Tao Ba, Wen Chen Cheng, Chang Rui Ren, Ling Yun Wang, Wen Jun Yin, Gang Zhou, Ke Xu Zou

Publication number: 20180238789Abstract: A particle concentration is determined by acquiring a particle concentration measurement at a reference station from each of a plurality of sensors to be evaluated. A reference particulate concentration measurement is acquired from a reference station sensor at the reference station. A base set of sensors is selected from the plurality of sensors based upon a correlation calculation. A reference sensor is selected from the base set of sensors. A model is constructed that specifies a relationship between the reference sensor and the reference station sensor. A generalized sensor type is formulated using one or more characteristics of the reference sensor. The generalized sensor type is used to construct an inheritance network model. A particle concentration for the generalized sensor type is determined based upon the inheritance network model.Type: ApplicationFiled: February 17, 2017Publication date: August 23, 2018Inventors: Yu Tao Ba, Wen Chen Cheng, Xin Jie Lv, Ling Yun Wang, Wen Jun Yin, Gang Zhou, Ke Xu Zou
