The framework has been put in place for the development of the AWG geophysical product processing systems. This development is to produce and test the scientific algorithms in a scalable operational demonstration environment -- STAR collaborate environment. The framework includes accommodations for all the Level 2 Advance Baseline Imager (ABI) products. The dependence of one product on the output of another product (product precedence) has been taken into account during the development of the framework. Data common to all the product systems have been read into the framework and passed to the appropriate product systems. These design features and the current status of the framework will be discussed. STAR Collaborative Research Environment  To develop and test scientific algorithms in a scalable operational demonstration environment  Hardware consists of operating systems that are within OSDPD  Multiple compilers are available for maximum code debugging capability  Develop algorithms using large quantities of simulated, proxy, and/or real data  The GOES-R AWG work is conducted within the STAR Collaborative Research Environment  Migrate and test AWG product systems  GOES-R AWG product validation.  Integration of AWG product systems into the AIT framework Organized Ancillary Data  Ancillary data used by more than one algorithm is read into the AIT framework and then passed to the individual product systems  This reduces the I/O time and removes unwanted redundancies  Current ancillary data that has been moved from product systems to the framework are:  NWP  Emissivity Current Status  Framework is in place  Completed parts:  NWP model ingest  Radiative Transfer Model installation  Configuration File Ingest  Current Work  Installation of the following product systems:  Cloud Mask  Sounds  Fire  Land Surface Temperature  NDVI  Aerosols ABIAOT Output retrieval results Retrieval over land 1.)
