GSICS Processing and Research Centres (GPRCs) shall recommend GSICS Products for the satellite instruments for which they have operational responsibility.
GSICS aim for the inter-calibration algorithm implemented by each GPRC to be as consistent as possible for a given class of instrument/channel. To ensure this the ATBDs are defined in a hierarchical structure, based on common general principles.
The ATBDs for each class of instrument are based on a consensus of the best method (or combination of methods) and a common reference instrument.
The finest level of the hierarchical ATBD allows for the specific details of each instrument to be considered.
The GSICS Coordination Center aim to implement a "baseline" algorithm based on the most consistent inter-calibration algorithm for all instruments within a class.
The baseline provides GPRCs with a reference against which they can compare their implementation.
The results of the baseline algorithm for a particular satellite instrument may be considered as official GSICS products upon approval of the GPRC that has operational authority for that instrument.
The development of the baseline algorithm is initiated within GSICS upon GRWG recommendation to, and acceptance of this recommendation by, the Executive Panel.
Developers are encouraged to research further improvements in the algorithms. If these can be shown to be beneficial, a new version of the Product can be released. This shall be accompanied by a new version of the baseline implementation, and other GPRCs implementations.
During a Product's progression through the GSICS Procedure for Product Acceptance, revisions can be made to the baseline by consensus agreement. These should coincide with changes between demonstration, pre-operational and operational status.
