Highlights A method to compute the water vapor path delay correction of altimeter sea surface height has been improved. This method is using total precipitable water measurements from scanning microwave radiometers. The method is applied to near real time production of Jason-2 and Cryosat-2 IGDR. The new correction improves the Cryosat-2 sea surface height accuracy.
Abstract This paper presents improvements of a method (Stum et al., 2011) aimed at computing the water vapor path delay correction of altimeter sea surface height, using total precipitable water measurements from scanning microwave radiometers. The main interest of this improved method is for the Cryosat-2 mission over the ocean. Focus is made on the applicability of the method in near real time. An experiment to produce an operational path delay correction for Jason-2 and Cryosat-2 Interim Geophysical Data Records (IGDR) has been set up. Results confirm that the new correction, although less accurate than the one attainable with an embarked radiometer, improves the Cryosat-2 sea surface height accuracy.
