  • Method of top-of-atmosphere reflectance-based spatiotemporal image fusion using aerosol optical depth
    Patent number: 10685230
    Abstract: A fusion method is provided to obtain a spatiotemporal image. The present invention is based on a conventional model—a spatial and temporal adaptive reflectance fusion model (STARFM). In the present invention, top-of-atmosphere (TOA) reflectance is kept in image fusion. Furthermore, Himawari-8, a geostationary satellite having a very high temporal resolution (10 minutes), is used. The present invention uses similar spectral bands as whose used for high-spatial-resolution image in satellites like Landsat-8 and SPOT-6. The present invention combines a high spatial-resolution image with a high temporal-resolution image obtained from Himawari-8. Thus, a TOA-reflectance-based spatial-temporal image fusion method (TOA-STFM) is proposed for generating an image having high spatiotemporal resolution. The present invention can be applied for air quality monitoring.
