Information on the products on this repository
These data is created using the R scripts with the random forest models and upscaling procedures found in: https://github.com/rocher-ros/RiverMethaneFlux.
Raw files to reproduce this product can be found in https://doi.org/10.5281/zenodo.7733604
The results of this analysis are published in the article "Global Methane emissions form rivers and streams" (accepted).
Main author is Gerard Rocher-Ros, for which correspondence can be sent to firstname.lastname@example.org
Units of the variables in the product are:
-River methane concentration: mmol CH4 m-3
-River methane diffusive flux rates: mmol CH4 m-2 d-1 (of river area)
-River methane diffusive emissions: Giga grams of C-CH4 (for each pixel).
The spatial resolution of the product is 0.25 degrees (which corresponds to around 27 km). The files are in WGS84.
There are four main products in this folder, packed as geotiff files, and described below.
+ The file "river_methane_yearly.tiff" contains three layers:
- Yearly average river CH4 concentrations (ch4_conc_avg)
- Yearly average river CH4 diffusive flux rates (ch4_flux_avg)
- Yearly total river CH4 diffusive emissions (ch4_emissions_year)
+ The file "river_methane_concs_monthly.tiff" contains twelve layers, with the modelled river methane concentrations for each month.
+ The file "river_methane_flux_monthly.tiff" contains twelve layers, with the modelled river methane flux rates for each month.
+ The file "river_methane_emissions_monthly.tiff" contains twelve layers, with the total river methane emissions for each month.
