This is an animation of the GRACE Gravity Model 01 which was released in July of 2003. This model is based upon preliminary data provided by the GRACE mission. The release of this preliminary model is a major advancement for oceanographers and a taste of scientific advancements yet to come from GRACE. Improved weather and climate change predictions now result from this model of Earth's gravity field 10 to 50 times more accurate than previous models.
