MODIS-Aqua Monthly Suspended Particulate Matter - OC-SMART AC
type: Dataset
description: The MODIS-Aqua monthly Suspended Particulate Matter concentration (SPM, measured in g·m-3) utilizes daily data from the MODIS sensor onboard NASA's Aqua satellite (MODIS-Aqua). This data has a nominal resolution of 1 km at nadir and is atmospherically corrected through the application of the Ocean Color - Simultaneous Marine and Aerosol Retrieval Tool (OC-SMART) (FAN et al., 2021). The SPM estimates are obtained from a blend of two SPM algorithms (Salah Salah et al., 2025). Subsequently, the SPM products are aggregated into monthly averages by calculating the geometric mean of daily SPM data over the respective month.
