Tidal variation restore using FES2014b

Hi Altimetry Community,

I'm wondering if it is possible to restore the tidal variation in the SARvatore products (Sentinel-3A) using FES2014b, the aforementioned because the tides are absent from SAR solutions (Sea Level Anomalies). I'm currently working in monitoring sea level in coastal zones using altimetry.

Any help or advice is very welcome!
Thanks in advance.

Hello dear User

 

yes of course you can restore the tidal variation.

The applied tide correction is in the field OET_Corr_1Hz (for 1 Hz case) and OET_Corr_20Hz (for 20 Hz case). 

You can make SLA_20Hz+OET_Corr_20Hz to restore the tide (20Hz case)

Pay attention SLA_20Hz has not the sea state bias (SSB) correction applied. 

You should take care to apply the SSB by your self making:

SLA_20Hz - SSB_20Hz 

 

All best

Dear Salvatore Dinardo,

Thanks for your reply. I applied the tide correction and sea state bias as you suggested and the results improved a lot.

Again, thank you very much for your help.

 

Best regards,
