Enviro-HIRLAM model output for April 2020 air pollution case study
收藏资源简介:
Case study: wildfires and dust storm air pollution events occured in April 2020 in the norther part of Ukraine (including the abandoned Chornobyl Exclusion Zone).The presented dataset contains the seamless Environment – HIgh-Resolution Limited Area Model (Enviro-HIRLAM) model output with a 1.5 km horizontal resolution. Period of study cover 5-30 April 2020. The model domain consists of 410×410 grid points in a rotated system of coordinates. Extracted for the 11 lowest Enviro-HIRLAM model levels. The model description can be found by the following link: https://doi.org/10.5194/gmd-10-2971-2017 Model configurations: (1) reference (REF) run without aerosol effects; (2) run with direct aerosol effects (DAE) included; (3) run with indirect aerosol effects (IDAE); and (4) run with combined direct and indirect aerosol effects (COMB). Domain and rotated system characteristics:- number of grid points along longitude = 410; - number of grid points along latitude = 410; - south boundary in rotated system of coordinates (deg) =-27.484;- north boundary in rotated system of coordinates = -21.349;- west boundary in rotated system of coordinates = -35.450;- east boundary in rotated system of coordinates = -29.315;- coordinates of South pole - latitude (deg) = 0.0;- coordinates of South pole - longitude =80.0 File format: NetCDF (converted from GRIB) Example of file names: "met_fc20200405_00+003.nc", "metflux_fc20200405_00+003.nc", "aer_fc20200405_00+003.nc", where "20200405" is 5 April 2020; "00+003" is 03UTC.
