This document describes and defines the prototype software for the generation of the Sentinel-1 Ocean Swell Spectra (OSW) component of the OCN product.
The main objective of the document is to provide a clear definition and description of the algorithm and processing system that are consistent with the S1 L2 processor.

📄 [DI-MPC-SETAP] Update of S-1 Instrument Timing Calibration for ETAD 2023 - PDF
Yearly (or Annual) Performance Reports provide the status of Sentinel-1 instrument and (L1/L2) product performance over the years. The annual document compiles key quality indicators during the reported year, and at times further in the past, highlighting eventual observed degradation or anomalous behavior. In particular, the following aspects are discussed:
L1: Impulse Response Function (IRF) key parameters, radiometric calibration/validation, geometric calibration/validation, NESZ calibration/validation, Radio Frequency Interferences (RFI)
L2: OCN Wind (OWI) calibration/validation, OCN Swell (OSW) calibration/validation and status on the OCN Radial Velocity product (RVL), which is not yet qualified.
The annual document also highlights the list of quality disclaimers and changes in processing baseline occurring during the reported year (due to processor version change or change in auxiliary data files). Finally, lists of relevant technical documentation and instrument unavailability are also appended.
The N-Cyclic Performance Reports provide information on product performance focusing on a period covering 4 cycles at a time. They provide interim reporting on L1 and L2 product performance before the publication of annual performance, allowing to timely identify eventual degradation.
The quality disclaimers provide a description of product performance degradation together with information on how to identify impacted products (for example, by SAR unit, acquisition time, generation time, etc). Each disclaimer file might contain information of several products affected by the same or similar anomaly.
The quality disclaimers contain a "percentage of degradation" of the impacted products. This percentage is an empirical estimation of the level of degradation, considering that a given degradation may have different impact on different users and their specific applications. It does not necessarily relate to the amount of products degraded. The following rule of thumb is used:
0 % degradation corresponds to no degradation. In fact, in that case there is no quality disclaimer.
1% is a degradation on meta data that can be overcome by the user, even if it is not convenient. The integrity of data is not affected.
1% can be as well a very a local degradation of the product data due to residual Radio Frequency Interference (RFI), that may prevent user to interpret the product in the affected areas. However, the presence of RFI is considered as useful information for some categories of users.
33% is used for L2 OCN data which nominally have three main components (OSW, OWI and RVL). This corresponds to a degradation of one third of the data, and applies for a large degradation of one of the three components of the L2 OCN products.
50% is a degradation that may impact the complete extent/coverage of the products, but not necessarily all users. For instance, the quality disclaimer 30 is on degradation of noise vector annotation, with impact on the complete coverage of the products that may impact certain applications, but not all of them.
100 % degradation corresponds to a complete degradation making the product useless for any application. It that case the product is removed from Sentinel-1 product catalogue.
Certain quality disclaimers correspond to reporting of specific product degradation on a given period. For instance, invalid annotation of burst ID on TOPS SLC products on a given cycle or product products containing residual RFI in a given month. In those cases, in addition to the "percentage of degradation" field, the quality disclaimer also contains the percentage of impacted products with respect to the total number of products of same processing level in the same period.

The Bottom of Rayleigh Reflectance (BRR) is a level 2 product over land that can be used in pixel classification. The Rayleigh correction formulation, defined for MERIS, remains pertinent for OCLI. One major improvement should be the use of a DEM of improved spatial resolution, and a smile correction is also simple to introduce.
