description: The MODIS-Aqua Daily Remote Sensing Reflectance (Rrs, unit sr-1) provides 8 spectral bands, temporal resolution of one month, and spatial resolution of 1 km over the Brazilian oceanic waters and the open ocean South Atlantic waters. This collection captures 7 visible and 1 infrared channels using Level-1A images acquired from the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument onboard NASA's Aqua satellite. The Level-1A data were processed into Level-1B and GEO using the Data Processing Tools (modis_L1B) from SeaWiFS Data Analysis System (SeaDAS) software. The Level-1B and GEO data were applied in the atmospheric correction OC-SMART (Fan et al., 2021) by the National Institute for Space Research (INPE, Brazil) and the Laboratoire d'Océanologie et de Géosciences (LOG, France), generating the Level-2 data. The Level-2 data has been mosaicked to generate daily maps capturing the complete Brazilian ocean waters. The daily mosaic data were reprojected to geographical (lat/lon) coordinates using the European Space Agency (ESA) Ocean Colour - Climate Change Initiative (OC-CCI) as a reference, then aggregated into a Level-3 grid. Both, the mosaic and the reprojection were done using the Sentinel Application Platform (SNAP).
