The HDF Group gave a presentation at the ESIP Summer Meeting about working with the CERES team to upgrade their HDF4 climate data products and make them more user-friendly. The HDF Group provided suggestions to the CERES team to structure the data according to Climate and Forecast Metadata conventions and update their HDF4 to HDF5 conversion tool. Working closely with science teams is a good model, as it allows The HDF Group to leverage their expertise in HDF features and product usability. A demo was also given of the new CERES data products.
