Comparison of the old (V1) and new (V2) neutral mass density observations of GRACE A in terms of orbit mean μ(ρV1, ρV2) (top) and orbit standard deviation δσ(ρ1, ρ2) (middle). Peak values exceeding the limits of the vertical axis are as low as 0.4 and as large as 2.0 in the orbit mean and as large as 200% in the orbit standard deviation. The accelerometer temperature is illustrated for reference (bottom).
