4 PoDAG Meeting Douglas Fowler, NSIDC DAACOctober 25-27, 2006 4 Release 28 Improvements Corrections are now applied for oscillator frequency  As a result all elevations are shifted about 2 cm in the horizontal  The relative elevations between operations periods shift less than 3 to 8 mm. There are now improved corrections for saturation effects and improved flags to aid in data selection.
