IPCC 2019 Tier 1 soil nitrogen emission and leaching factors.

IPCC 2019 Refinement Tier 1 default factors for managed soils: direct N2O emission factors for N inputs (EF1), flooded rice (EF1FR) and urine and dung deposited by grazing animals (EF3PRP), the indirect N2O factors for volatilisation and redeposition (EF4) and for leaching and runoff (EF5), and the leaching fraction FracLEACH-(H). Many are given as an aggregated value and as wet and dry climate values. A climate is wet if annual precipitation / potential evapotranspiration (PET) is greater than 1 in temperate and boreal climates, or annual precipitation is greater than 1000 mm in tropical climates (Table 11.1, footnote 4); otherwise it is dry.

Format

A tibble with columns:

parameter: IPCC parameter name: "EF1", "EF1FR", "EF3PRP_CPP", "EF3PRP_SO", "EF4", "EF5" or "FracLEACH_H".
disaggregation: Climate or water-management stratum the value applies to, e.g. "aggregated", "wet", "dry".
value: The factor.
unit: Unit of the factor.
source: Locator of the value in the IPCC 2019 Refinement.
