The ICESat-2 SIPS (Science Investigator-led Processing System) software development team is preparing to design and implement ICESat-2 standard data products. The team has initiated two distinct but related efforts to identify and prototype standards and conventions that are applicable to the ICESat-2 standard data products. The first effort consists of converting current ICESat GLAS binary data products into HDF5. This is a 7-month task restricted to adopting and implementing an initial snapshot of standards and conventions. The second effort is a longer-term activity using a prototype SIPS to design and create scientific data products for MABEL, an aircraft-based ICESat-2-like photon-counting instrument. The MABEL effort will extend past the end of the GLAS conversion effort and will prototype standards and conventions deemed too ambitious for the GLAS conversion. Both prototype efforts feed directly into the ICESat-2 standard data product design process. The overall goal is to create and design standard data products that will be standards-compliant, enable interoperability between ICESat and ICESat-2 data, and promote data interoperability with other present and future Earth Science missions.
