Tentative calibration of EIGEN 2 using satellite crossover altimetry data
Abstract
EIGEN 2 (GFZ+CNES) is a new gravity model based solely on about one year of the CHAMP data. The formal covariance matrix of EIGEN 2 is available and a calibration/scaling factor or factors are sought. EIGEN 2, completely independent of any satellite altimetry, is ideal for testing by means of long-term averaged, accurate and carefully corrected single-satellite crossovers, using the crossovers themselves as well as the latitude lumped coefficients. Data from ERS 1/2 and Geosat are used.
