Getting to know the oceans Mean Dynamic Topography (MDT) derived from the satellite altimetry data helps to study climates and steady state currents in the oceans. A MDT model named as MDT_IAU_TN_2014, including steady state surface currents was developed by the Islamic Azad University of IRAN, Tehran-North branch, hydrography group. The model includes magnitudes and directions of currents in the region of Persian Gulf and Indian Ocean given in a grid with 2’x2’ arc minutes spacing in the latitude and longitude directions. To build up the model, a Mean Sea Surface (MSS) model should be subtracted from a Geoid heights model. An MSS called MSS_IAU_TN_2014, is derive using observations of 21 years of 6 altimetry satellites: Topex-Poseidon (T/P); ERS (E1) and (E2); Jason (J1) and (J2); Geosat Follow-On (GFO). MSS_IAU_TN_2014 differences relative to the MSS_CNES_CLS_2011 has 0.1 m RMS. Also a series of global geopotential coefficients estimated from four years of GOCE data is used to compute the geoid. A truncated Gaussian Filter with truncation radius of 1.386 arc degrees was used to match the spectral content of both MSS and Geoid. Sea Level Anomaly (SLA) an In-Situ data could be used to make the MDT_IAU_TN_2014 independent from any other models. At last, MDT_IAU_TN_2014 was compared with MDT_CNES_CLS09 0.51m RMS and MDT_DTU_2010 with 0.033m RMS. Velocity vectors from MDT_IAU_TN_2014 shows near coast currents perfectly, but there is some weakness in Oman Sea gyres details.
