  Terra Fusion is NASA ACCESS 2015 project. Terra Fusion is an ultimate test dataset for the existing software stack around netCDF and cloud. Terra Fusion helped us to find issues in Hyrax, THREDDS, GDAL, and ArcGIS. For example, GDAL alone can't handle TerraFusion properly since netCDF swath handling needs improvement. SDT is necessary to read lat/lon and reproject swath to grid. We subsetted MODIS and created an aggregated netCDF. Then, we created a mosaic dataset directly from the aggregated netCDF. Here, there are a lot of technical details but the valuable lesson is that the meeting the CF convention conventions alone is not enough to make dataset fully interoperable with GDAL and ArcGIS.
