Nitrogen and Carbon fixation by cryptogams

Carbon and Nitrogen fixation by cryptogamic ground and plant cover in g/m^2/yr as published in Fig. 3 (MODIS) and S2 (Olson) of Elbert et al. (2012), DOI:10.1038/ngeo1486 Each file contains 3 variables: CGC: fixation by cryptogamic ground cover<br>CPC: fixation by cryptogamic plant cover<br>CGC_CPC: the sum of both Keep in mind that not all ecosystems were covered and "empty" areas or low values do not mean nothing is fixed there by cryptogams.
