Comparison of GLOUP botom pressure data with barotropic Kalman filter
results (kf019) and control integration (c20000630):

Map of bottom pressure measurements is here[1] . Coherency squared
between c20000630 and gloup data (simulation) and kf019 and gloup data
(assimilation) is here[2] . Barotropic Kalman filter bottom pressure
estimates are more coherent with observations than the control
integration for periods longer than 20 days.

Raw time series:
 52 E, 46 S[3]
 53 E, 47 S[4]
 69 E, 48 S[5]
 78 E, 38 S[6]
 302 E, 55 S[7]
 302 E, 57 S[8]
 304 E, 58 S[9]
 305 E, 61 S[10]
 305 E, 60 S[11]
 324 E, 32 S[12]

Follows table of variance, residual variance, and skill where skill is
defined as:
