Update From Aquarius PI Gary Lagerloef: First Light Image Released[23-Sep-11] I am pleased to say that an Aquarius "first light" image was the subject of a NASA Press Release on Thursday, and is generating quite a bit of excitement. You can see the image and learn more about it at the following links:

There are a few other things to know about the image: It is a composite of the first two and a half weeks of data since Aquarius became operational on August 25. These data contain uncertainties, and calibration and data validation work remains. Measurements in the southernmost ocean regions are not yet reliable as they are associated with high winds and low surface temperatures. The north-south striped patterns visible throughout the image are artifacts of small residual calibration errors and thus are not real. Low salinity values immediately adjacent to land and ice-covered areas are due to proximity to coastlines or ice edges, which introduces errors into the data. Although preliminary near-shore corrections have been applied, these will require additional analyses to correct.
It's a very good start. Enjoy the view!
