Data and analysis code for: Methane emission factors for Boro and Aman rice in Bangladesh: a systematic review and site-level comparison of inventory approaches

This dataset accompanies the review "Methane emission factors for Boro and Aman rice in Bangladesh: a systematic review and site-level comparison of inventory approaches" (M. Kamruzzaman). It contains seasonal methane (CH₄) and nitrous oxide (N₂O) values extracted from seven peer-reviewed field studies of Boro (dry-season) and Aman (monsoon) rice in Bangladesh: 13 baseline site-seasons under continuous flooding and mineral fertiliser; 18 paired comparisons of alternate wetting and drying, urea deep placement, N rate, and manure or compost; 32 treatment-level records comparing IPCC Tier 1, Tier 2 and Tier 3 estimates with site-level measurements; 12 N₂O emission-factor estimates. Supplementary Tables S1–S8 of the article are included. The Python code (MIT licence) reproduces every number, table and figure in the article. That covers the pooled emission factor (1.55 kg CH₄ ha⁻¹ d⁻¹; 95% CI 1.32–1.81) and its prediction interval, the mixed model, the sensitivity analyses and the national estimates. The national estimates include a reconstruction of the national inventory in Bangladesh's First Biennial Transparency Report. The code also covers the site-level consistency check. To reproduce the results, run python run_all.py in the code folder. README.md describes the folder structure and every variable. The values were extracted from the published studies cited in the article, so please cite those studies as well as this dataset.
