The Sentinel-6 PDP configuration update to Processing Baseline F06 only impacts High Resolution (HR) data for all timeliness. This update results in a significant improvement in the quality of HR geophysical retrievals. The new baseline reduces the number of Doppler beams (a.k.a looks) incoherently integrated within the stack to generate the multi-looked L1B power waveforms. This reduction, from originally 448 looks to now 322 looks, allows for not accounting in HR altimetry for undesired Doppler ambiguity effects within the stack observed from beginning of mission until present. With this new baseline, Significant Wave Height (SWH) differences between HR and LR are considerably reduced, and range differences between LR and HR are less dependent on SWH.

Product format and size remain unchanged.
