[1] In the paper “Radiation belt electron precipitation into the atmosphere: Recovery from a geomagnetic storm” by C. J. Rodger et al. (Journal of Geophysical Research, 112, A11307, doi:10.1029/2007JA012383), the order of equations (3) and (4), as well as (6) and (7), were given incorrectly. These equations describe the effective recombination rates in the D-region of the ionosphere, $\alpha_{eff}$. The correct order for the equations are given below.

[2] For nighttime equations, small changes are made in the Rodger et al. [1998] expressions to provide the best quality agreement with SIC nighttime calculations. For altitudes above 80 km,

$$ \alpha_{eff} = 2.0 \times 10^{-12} (T_e/300)^{-0.55} \text{ m}^3\text{s}^{-1}, \quad (3) $$

where $T_e$ is the electron temperature, while for altitudes of 80 km and below,

$$ \alpha_{eff} = 2.5 \times 10^{-11} \sqrt[3]{300/T_e} \text{ m}^3\text{s}^{-1}. \quad (4) $$

For daytime equations, the following is used for altitudes above 84 km,

$$ \alpha_{eff} = 5.0 \times 10^{-13} (T_e/300)^{-0.55} \text{ m}^3\text{s}^{-1}, \quad (6) $$

while the following is used for altitudes of 84 km and below,

$$ \alpha_{eff} = 3 \times 10^{-12} \sqrt[3]{300/T_e} \text{ m}^3\text{s}^{-1}. \quad (7) $$
