ICON-ART PRIEST v1.0 monthly model output

This dataset provides monthly-mean output from ICON-ART PRIEST v1.0, an extension of ICON-ART designed to simulate the transport, transformation, and deposition of Perfluoroalkyl Carboxylic Acids (PFCAs) in the global atmosphere. The product contains 4-D global fields (time × height × latitude × longitude) of mass concentrations for three PFAS-related tracers: PFOA: mass_concentration_of_perfluorooctanoic_acid_in_air (kg m⁻³) PFNA: mass_concentration_of_perfluorononanoic_acid_in_air (kg m⁻³) 8:2-FTOH: mass_concentration_of_8_2_fluorotelomer_alcohol_in_air (kg m⁻³) File format: NetCDF.Dimensions: time × lon × lat × height = 178 × 360 × 181 × 60.Coordinates: lon (degrees_east), 360 points on a regular longitude grid. lat (degrees_north), 181 points spanning the globe. height_3 (standard_name: height; long_name: generalized_height), 60 vertical levels. time in minutes since 2000-01-01 (gregorian) with a bounds attribute referencing time_bnds.Temporal coverage: nominally 2005–2019 (see the time coordinate for exact start/end months).Units & missing values: tracer units are kg m⁻³; missing data are encoded as NaN. Source: Processed tracer output from an ICON-ART PRIEST model simulation.Creator: Hiram A. Meza-Landero.Intended use: analysis of global distribution, seasonality, and interannual variability of atmospheric PFOA, PFNA, and 8:2-FTOH; model–observation comparison; and PFAS transport studies.
