Surface winds over oceans are required for several operational, oceanographic, atmospheric and climatological studies. OSCAT Daily Wind Composites have been generated by interpolating OSCAT level-2B wind fields using Variational Inverse Method (VIM) inbuilt in Data-Interpolating Variational Analysis (DIVA) software. These products will have their utility in daily weather and modeling activities. The output products consist of zonal and meridional wind components with their respective error fields as computed by DIVA. Further details have been provided in the technical document.
