In the paper “Spatial and temporal dynamics in eddy covariance observations of methane fluxes at a tundra site in northeastern Siberia” by F. J. W. Parmentier et al. (Journal of Geophysical Research, 116, G03016, doi:10.1029/2010JG001637, 2011), a few typographical errors have been brought to our attention which have unfortunately slipped through, and we apologize for any inconvenience they may have caused.
 In equation (1), the conditions of L > 0 and L < 0 were reversed, and in the second part of the equation, a minus was given where a plus should have appeared. However, these mistakes are purely typographical. The same errors were not made in the code used, and all calculations presented in the paper were made with the correct equation, shown here in equation (1). Therefore, both the results and the conclusion of the paper remain unchanged. The correct equation is:
 Furthermore, in the last sentence of paragraph 21, the word “unstable” was given twice, while the second occurrence should have read “stable.” The correct sentence is: “As a consequence, unstable conditions are expressed in the range 0 < Φ < 1, neutral conditions occur at Φ = 1, and stable conditions are expressed for values of Φ > 1.”
 We'd like to thank Bernard Heinesch and students for bringing these typographical errors to our attention.
