  "description": "This long-term dataset contains monthly Level 3 (L3) gridded ammonia (NH3) total column data derived from IASI (Infrared Atmospheric Sounding Interferometer) measurements onboard Metop-C (Meteorological operational satellite-C) data produced as part of the European Space Agency's (ESA) Climate Change Initiative (CCI) Precursors for aerosols and ozone project. The temporal range of this dataset is from September 2019 to June 2025. Full documentation can be found at the project website https://climate.esa.int/en/projects/precursors-for-aerosols-and-ozone/.The version number is 4.0.1R. Data are available in NetCDF format.This dataset forms part of the ESA Precursors Climate Change Initiative (Precursors_cci): Precursors IASI NH3 L3 data products v4R.  doi:10.5285/463862326d574951bea52527f9df397d. https://dx.doi.org/10.5285/463862326d574951bea52527f9df397d",
