| Abstract | A special expedition was launched by the National Center for Antarctic and Ocean Research (NCAOR), India on board R/V Akademik Boris Petrov during 25 January to 1 April 2006 passing the Southern Ocean and reaching the Larsemann Hills area of East Antarctica. The surface layer in-situ data generated from the cruise are compared with that obtained from the NCEP reanalysis during the same period along the track of the vessel. It is concluded that the NCEP reanalysis sea surface temperature and air temperature have some discrepancies as the vessel enters the sea ice zone near the Antarctic coast. The air pressure is well modeled but the relative humidity shows high variability throughout the period of the study. The wind speed is poorly correlated with that obtained from the NCEP due to the use of "Course over the ground" in place of ship "heading" while calculating the true wind. |
