Gridded NRT Wave products:
We inform all the users that the Copernicus Marine Environment Monitoring Service CMEMS is now in charge of the processing and distribution of the gridded (L4) NRT wave products. Indeed in the frame of the Transition AVISO+ to CMEMS, AVISO+ focuses on the distribution of innovative products whereas CMEMS is dedicated to the operational products and services.
Since July 2019, gridded L4 wave NRT products (called WAVE_GLO_WAV_L4_SWH_NRT_OBSERVATIONS_014_003) have been added to the CMEMS catalogue. 
Therefore the CMEMS catalogue disseminates Near-Real-Time gridded L4 wave products as well as two along-track L3 wave products (altimetry and spectral)

Thus, the production of the AVISO+ gridded L4 NRT wave products will stop by December 3 2019. As for the moment, this Aviso+ time series is not homogeneous in time, and it is the only one provided before 2019, it has been decided to reprocess it since September 2013.

Compared to AVISO+, the CMEMS gridded L4 wave products on a 2°x2° grid are based on several up-to-date missions and benefit from an improved processing fully described in the CMEMS QUality Information Document: QUID
You will find the list of AVISO+ and CMEMS wave products in the document Migration AVISO+ to CMEMS and AVISO+ to C3S (section 8) and a brief overview of the differences between the two L4 NRT wave products and the reprocessing details in section 8

For the moment on CMEMS, only the NRT products are distributed beginning on July 2019. It is planned to disseminate a Delayed-time product on CMEMS by the beginning of 2021.

So the user is invited to register to CMEMS as soon as possible: the useful links to CMEMS are indicated in the  document Migration AVISO+ to CMEMS and AVISO+ to C3S.

Gridded NRT Wind products:
Concerning the gridded L4 NRT wind products , it is planned to stop the production on December 3 2019 and to deliver a reprocessed time series. All information in the document Migration AVISO+ to CMEMS and AVISO+ to C3S (section 9)
