Worldview Image of the Week

Iguazu Falls, Argentina and Brazil

Image captured on Oct 10, 2023, by the OLI instrument aboard the Landsat 8 and 9 satellites.

True-color reflectance (Nadir Bidirectional Reflectance Distribution Function [BRDF]-adjusted) image of Iguazu Falls on the border of Argentina and Brazil. Iguazu Falls is in the center of the image, where the wider upper Iguazu River stairsteps down into the lower Iguazu. As a reversed J-shaped river bend, the right bank is on the Brazil side and the left bank is in Argentina. This image was acquired on October 10, 2023, by the Operational Land Imager (OLI) aboard the joint NASA/USGS Landsat 8 and 9 satellites. Explore the Iguazu Falls area in Worldview.

The imagery, available in NASA's Worldview, are part of the Harmonized Landsat and Sentinel-2 (HLS) project, which provides 30-meter resolution, true-color surface reflectance imagery from the OLI and OLI-2 instruments aboard the joint NASA/USGS Landsat 8 and Landsat 9 satellites and the Multi-Spectral Instrument (MSI) aboard the ESA (European Space Agency) Sentinel-2A and -2B satellites. The data from the two instruments aboard the four satellites are processed through a set of algorithms to make the imagery consistent and comparable across the instruments. This includes atmospheric correction, cloud and cloud-shadow masking, spatial co-registration and common gridding, illumination and view angle normalization, and spectral bandpass adjustment.
