Correction to "Using thermal time and pixel purity for enhancing biophysical variable time series: An interproduct comparison" [Apr 13 2119-2127]

There is an error in the above-named article [ibid.,vol. 51, no. 4, pp. 2119-2127, Apr. 2013] regarding the definition and the implementation of equation (3), defining the proposed temporal smoothing index (TSI). The correct formula is provided. These corrections do not change any of the general conclusions of the paper, but some of the comments regarding the interpretation of this table are revised.
