This dataset is a model output from the European Monitoring and Evaluation Programme (EMEP) model applied to the South Asia driven by Weather and Research Forecast model meteorology (WRF). It provides daily mean atmospheric compositions and fluxes of the South Asia on a 0.1° x 0.1° resolution grid for years 2015 and 2030.
The EMEP model version used here is rv4.45, and the WRF model version is the 4.4.2.
This work was carried out within the South Asian Nitrogen Hub funded by the UK Global Challenges Research Fund (GCRF) of UKRI administered by the Natural Environment Research Council (NERC) (NE/S009019/1).

Provenance & quality
Daily average concentrations for a model domain covering the South Asia with a resolution of about 0.1°x 0.1° were calculated using the EMEP atmospheric chemistry transport model.
The data were processed from the full EMEP model output to a subset containing essential variables only. The Climate Data Operators version 1.9.10 was used to subset the model output.
