We are working with the Priceton Ocean Model (POM). We have reasonably well simulated the sea level using POM. Since we are new to the assimilation field, can anyone suggest the best method to be adopted for SLA assimilation for mesoscale studies?
pls refer to our papers: Title: The 4-D structure of upwelling and Pearl River plume in the northern South China Sea during summer 2008 revealed by a data assimilation model

Thank you very much dr D.Wang. We are Implemeted POM at Gulf of Khambat on the west coast of India. Your experience and suggestions will help us to improve a lot.
you can improve the results by adding the tidal effects in the model. particularly for the Gulf of Kambhat simulations, grid generation play a prominent role. please take care of these two things to improve your results.
Thank you dear sir. I am looking foreward for your suggestions to improve the model. recently we have incorporated the tide at stations and seems it simulate reasonably well. now we are trying to assimilate altimeter data will it be more reasonable.
if your problem is to process the SLA alongtrack, i developed a routines to obtain the sea level anomalies alongtrack from Jason-1.
Hi dear Carlos, thank you for your reply. That will be very much helpful for me. I am only a beginner in assimilation field, We successfully implemented POM in coastal waters of India and well validated with tide and currents. I would like to get your suggestions regarding the processing levels required for altimeter data of coastal areas and also the best assimilation tool which i should prefer. I will be obliged for your support and suggestions.
Hi Mohammed Salim, We have assimilated along track SLA using Ensemble Optimal Interpolation technique. My suggestion is that before you jump into the data processing part, first you decide which technique you want to use and then make step by step algorithm. Then you will get an idea of the format of the datasets to be used.
Thank you so much. If you can provide me some basic manual or documents or papers regarding assimilation for a beginner. it will be so much helpful to me.
There are so many books and papers available on data assimilation. I hope this paper will provide you a beginning in Ensemble Kalman Filter.

Hi, I am attempting to use POM. Some clarification is needed regarding the time varying surface flux forcing. In what units are wtsurf, wssurf and swrad are to be input into the model? Can any one give the information? Thanks in advance.
