Questions on data processing and products Data Processing Q Which version of the AATSR IPF was used to produce my data?
The AATSR IPF version number is a field within the Main Product Header of the data. Volume 5 of the ENVISAT Product Specification (Product Structures) details the contents of the product headers.
