General structure of the Product Guides

Several sections are included in all Product Guides:

  1. An Introduction defines which products are going to be addressed. Generally, the Product Guides are intended to cover products generated in the EUMETSAT EPS Core Ground Segment, which consist of up to Level 1b for ASCAT, GOME, GRAS and AVHRR/3 and up to Level 2 for ATOVS and IASI. The EUMETSAT Satellite Application Facilities take the processing to higher levels for several of the EPS instruments, and in that case the relevant SAFs are introduced and a pointer to their corresponding information pages and/or help desks is also given.
  2. A list of Reference Documentation is given for each Product Guide, including the source of the information or in some cases recommended further reading.
  3. Product Configuration History is then introduced. The contents of this section will be available as soon as the products become operational.
  4. A Product Overview section then follows, including a wide overview of the relevant instrument(s), the data processing, available products, general product contents and a summary of potential applications. This section is intended to introduce the products to potential users and to help the users to choose which product is more relevant for their application.
  5. A section of EPSView is included here to introduce how the EPSView tool can be best exploited to get familiar with the products addressed in this particular guide.
  6. An overview of the Product Formats and Dissemination intends to tell the user how to get the data, which dissemination means are available and in which formats the products are available. An introduction to the different formats is here included, including EPS Native, HDF5 and WMO formats. Note that different formats do not always include the same structure/information for a product. The product structure/contents of the EPS Native format is here given in detail, and the other formats are described in relation to it. The format description in this section is limited to product sections. Further dissection of the products down to field and even bit level is offered in several Annexes of each Product Guide.
  7. A detailed account of the product Processing Algorithms is given here. At this stage, this section has not yet been developed for any of the Product Guides, but a reference is given to the appropriate Product Generation Specification documents.
  8. Product Validation is then addressed, highlighting the product validation activities, methods and conclusions on accuracy for a given operational product. At this stage, this section has not yet been developed for any of the Product Guides, but a reference is given to the appropriate Calibration and Validation plans.
  9. Finally, Product Routine Monitoring is described and pointers to the location of the latest statistics on product performance and availability is given. At this stage, this section has not yet been developed for any of the Product Guides, but a reference is given to the appropriate Calibration and Validation plans.

Several Annexes complement the main body of information of each Product Guides. The following are common Annexes to all guides:

Specific Annexes to each Product Guide include, among others, a detailed description of the contents and format of the relevant EPS native product, down to bit level.

Product Guides evolution and configuration control

The evolution of these on-line Product Guides will be handled separately for every guide. In the cover page of each guide, a link to a page describing a history of changes to each section will be included. The dates of each modified page will be updated consistently with the last modification. Modifications related to document formatting will not be recorded, only relevant content changes. Every time a modification is made to a file, a new PDF will be generated, and only the latest PDF compilation will be accessible to the user through these pages.
