Correction to: Nature Communications 10.1038/s41467-020-15687-x, published online 15 April 2020
The original version of this Article contained an error in Fig. 4c, in which y-axis label of “Normalized Emissions Ratio” was incorrectly given as “R/G”. The correct label should be “G/R”. This has been corrected in both the PDF and HTML versions of the Article.
