N2 and  N2O concentrations and fluxes for the six large river networks in China

This dataset is a collation of 4-year direct measurement values of N₂ and  N₂O concentrations and fluxes for the six large river networks in China, along with information on location, hydrological, physical, and chemical conditions of the 56 sampling sites. These data will be very valuable for balancing the regional and global N budget. In addition, the Monte Carlo simulation code for upscaling and analyzing uncertainties are presented here.
