• The authors regret that an error was made when creating Table 1. For the Mt. Kenya campaign, the values listed in the column “MAAT (Peterse et al., 2012)” were the in situ temperatures instead of the temperatures derived from Peterse et al. (2012) calibration. This error is corrected in the Table 1 below. This error does not change any fundamental conclusions of the paper as the correct temperature values were used to develop the calibrations presented.• In addition, the source used to determine the temperature lapse rate along Mt. Kenya was not well referenced. The temperature values were derived from the Worldclim global climate dataset (Hijmans et al., 2005) instead of the association of the Kenya Meteorological Department (1984), Camberlin et al. (2014) and Smith (1993) data. Please note that the given temperature lapse rate was correct. This correction has thus no impact on the fundamental conclusions of the paper.The correct sentence in the materials and methods part should be: “Based on meteorological data from weather stations along Mt. Kenya and in Central Kenya (WorldClim; Hijmans et al., 2005), temperature lapse rate along Mount Kenya was determined as 0.63 °C/100 m.” The authors would like to apologize for any inconvenience caused.
