Ocean Sciences

To address the effects of climate change on different components of the complex Earth-Ocean-Atmospheric system, many products are being generated under NICES programme which represent the ocean dynamics such as Ocean Surface Winds, Ocean Wind Stress, Ocean Color, TCHP etc. These products play an important role in understanding the spatial and temporal distribution of sea surface salinity, ocean thermodynamics and its circulations etc. and the interaction between the ocean and atmosphere. Following table lists out the various products available under NICES.

Several products are generated which represent the ocean dynamics such as Daily Ocean Heat Content of 700m Layer, Daily Tropical Cyclone Heat Potential, Ocean Heat Content (OHC) and Ocean Mean Temperature (OMT) at different Depth, Ocean Surface Winds, Ocean Wind Stress, Wind stress curl, Ekman Currents, Geostrophic Currents, Sea Surface Height Anomaly of SARAL AltiKa, Ocean Surface Currents, Eddy Kinetic energy EKE, Monthly Mean Sea Level Anomoly (MMSLA), Ocean Color Datasets for North Indian Ocean, Chlorophyll Concentration, Diffuse Attenuation, Sea Level Pressure, Co-Tidal Map, 26 Degree Isotherm, etc.
