Air Pollution Emissions from Line Sources in Grid Format (TWD97)

Grid-based air pollutant emissions data from line sources. The base year for the estimation is 2023 (ROC Year 112). The grid covers Taiwan's main island and offshore islands. The coordinates of the lower-left corner of each grid cell are based on the TWD97-TM2 coordinate system, using the 121° central meridian for the main island and the 119° central meridian for the offshore islands. The air pollutants covered include TSP, PM10, PM6 (not estimated), PM2.5, SOx, NOx, THC, NMHC, CO, and Pb.
