Based on the nitrous oxide (N2O) emission model developed by Maavara et al. (2019, GCB) and the HydroLAKES database, we simulated the average annual N2O emissions from 1.4 million lakes and reservoirs. We give bounded estimates of N2O emissions based on emission factors of 0.3%, 0.9% and 1.5%. We have gridded the model outputs at a resolution of 0.5 degree (i.e. ~50 km), and report emission fluxes normalized by total grid cell area. In addition, we report the areal proportion of lakes and reservoirs, which can be used to transform these emission estimates into N2O emission rates per water surface area. All estimates are reported for four types of standing water bodies: 0) All lakes and reservoirs, 1) Natural lakes w/o dam constructions, 2) Reservoirs, and 3) Regulated lakes. This classification of lake types was directly adopted from the HydroLAKES database. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.900565"!
