  2. Data-based analysis of DBx at GEO Statistical interpolation combines observations with a background model, to improve the estimated state globally. The figure shows predicted DBx at the position of GOES-12, computed from the Tsyganenko (2001) field model and data from GOES-10.

  3. Estimating error correlations in the Tsyganenko (2001) B-field model Statistical interpolation requires error structure of background model. Here, error correlations are estimated numerically, by perturbing model inputs and parameters. Left: contours of DBz error correlation coefficient, relative to point marked “+” in equatorial plane.
