Retrieving pollution emission source using CFD and satellite data

A method for modeling air pollution, comprising:

• receiving a weather model for a particular geographic region;
• receiving satellite-observed pollution observation data over the geographic region;
• generating a physical dispersion model for pollution over the geographic region using the received weather model;
• interpolating the received satellite-observed pollution observation data to the generated physical model to produce a hybrid weather model;
• and
• optimizing the generated physical dispersion model by minimizing a difference between one or more observed emissions levels taken from the satellite-observed pollution observation data at one or more locations and calculated emissions levels at the one or more locations that are calculated from the physical dispersion model,
• wherein the hybrid weather model has a greater resolution than the received satellite-observed pollution observation data alone.

A computer system comprising:

• a processor;
• and
• a non-transitory, tangible, program storage medium, readable by the computer system, embodying a program of instructions executable by the processor to perform method steps for modeling air pollution, the method comprising:
• receiving a weather model for a particular geographic region;
• receiving satellite-observed pollution observation data over the geographic region;
• generating a physical dispersion model for pollution over the geographic region using the received weather model;
• interpolating the received satellite-observed pollution observation data to the generated physical model;
• and
• combining the interpolated satellite-observed pollution observation data and the generated physical model using weighted coefficients for both the interpolated satellite-observed pollution observation data and the generated physical model to produce a hybrid weather model,
• wherein the weighted coefficients are calculated in accordance with a relative error in both the physical dispersion model and the satellite-observed pollution observation data, and
• wherein the hybrid weather model has a greater resolution than the received satellite-observed pollution observation data alone.
