AB: Giovanni, a web-based application developed by NASA Goddard provides a simple and intuitive way to visualize, analyze and access vast amounts of Earth science satellite remote sensing data and model simulations without having to download the data and programs to read. One of the instances in Giovanni is cloud, aerosol and other atmospheric data products from Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Terra (EOS AM) and Aqua (EOS PM) satellites. Recently, the next generation of MODIS data products, tagged Collection 005 and remarked by significant improvements, have been released to replace the earlier Collection 004 data products. This paper will present a variety of intercomparison results between the two satellite and the two versions of aerosol and cloud data products. The intercomparison studies will help to better evaluate and validate the variability of aerosol, cloud and other related atmospheric physics in the multiple years satellite remote sensing data, and satellite, sensor and retrieval algorithm related issues. MODIS aerosol and cloud products will be also compared to the Goddard Chemistry Aerosol Radiation and Transport (GOCART) model simulations, the Multi-angle Imaging Spectroradiometer (MISR) aerosol products and other A-Train active aerosol and cloud measurements for future data fusion among multiple satellites and sensors to maximize the satellite remote sensing data usability and generate the best data products for science applications.
