Downloading World Ocean Atlas 2009 and Loading it into Matlab

Online Oceanographic Datasets and Data products

If the code or instructions below are helpful to you, I'd love to hear it. Always nice to know whether it's worthwhile to put these kinds of instructions online. (Send me an e-mail at the address above.) Even better, if you encounter and fix a relevant data-access issue that isn't in the "troubleshooting" below, let me know so I can add it to the page.


Gridded AVISO altimetry

URL: AVISO global products on a 1/3 x 1/3 deg grid.
  1. For geographic and temporal extraction go to geographic and temporal extraction page. Scrolling down the page, choose your poison. These use the same codes as above, DT/NRT and MADT/MSLA. Make sure you're global unless there's a specific region you fall into that they focus on (like mediterranean).
  2. Click your choice
  3. Choose "Downloading and extraction service" to follow the rest of these instructions. If you're familiar with OpenDAP that might be a better option for you.
  4. Fill out the form keeping "netcdf" as the format, filling in the appropriate lat/lon limits, and the time range of your choice. Check both the Grid_0002 and Grid_0001 boxes.
  5. Click "Download"
  6. Save the file, which includes little tags to indicate what data you chose
  7. Use the script to convert to a matlab structure here: load_aviso_uv_scr.m. Change the appropriate file names, latlon limits and export filename according to what you filled into the form.
