    Description

    This dataset contains information about annual estimates of fine particulate matter (PM2.5) concentrations and trends beginning in 1998. PM2.5 refers to airborne particulate matter less than 2.5 µm in diameter; comprises several chemical and particulate constituents, including nitrate, ammonium, elemental carbons, organic carbons, silicon and sodium ions and dust, and originates from a variety of sources,...

    Description

    This dataset contains information from global Moderate Resolution Imaging Spectroradiometer (MODIS) vegetation indices, which are designed to provide consistent spatial and temporal comparisons of vegetation conditions. Gridded vegetation index maps depicting spatial and temporal variations in vegetation activity are derived at 16-day and monthly intervals in support of accurate seasonal and inter-annual...

  • Modern-Era Retrospective analysis for Research and Applications, Version 2

    Alternate Title(s)
    MERRA-2
    Description

    This dataset contains information from The Modern-Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2), which provides global modeling data beginning in 1980. MERRA-2 builds upon the original MERRA project's two primary goals: to place NASA’s Earth Observing System (EOS) satellite observations in a climate context and to improve the representation of the atmospheric branch...

    Description

    This dataset contains daily global gridded (0.25 x 0.25) Nitrogen Dioxide Product (OMNO2d) concentrations. Nitrogen dioxide (NO2) is produced in the troposphere, where it is a precursor to ozone production, and plays a key role in ozone chemistry in the stratosphere; it is also an indicator of poor air quality. These data, which are derived from the Ozone Monitoring Instrument (OMI) aboard NASA’s Earth...
