1.1.7 Summary of Applications vs. Products

Level 1B products are routinely produced and archived but not distributed to Users. Users requiring the altimeter waveforms will find them conveniently stored in the L2 SGDR product with collocated geophysical corrections and the output of the four retracking algorithms. In other words, the SGDR product holds the full GDR product augmented by averaged and individual echo waveforms. Therefore users of ENVISAT Altimetry need not access the Level 1B products.

 

The table below shows the applicability of the L2 products to various user applications. This table provides a quick reference whereas the products are described in detail in RA2/MWR Products and Algorithms(Chapter 2. ) .
