The <Metadata_Association> field describes metadata associated with the data set; i.e., the name and other details of input data, data sets associated (in science data terms) with the instance and/or data sets dependent on the collection. <Metadata_Association> can also be used to relate generalized aggregated metadata records (parents) to metadata records with highly specific infomation (children).
<Description>Near real-time (NRT) data are available from MODAPS for certain Aqua and Terra MODIS L0, L1, L2, L2G, and L3 products. Whereas the standard MODIS forward processing acquires 2-hour L0 files for Aqua and Terra from EDOS within 7-8 hours of real time, LANCE-MODIS acquires session-based L0 files from EDOS and the end of the session is available within 10-30 minutes after real time.</Description>
