Atmospheric ammonia can change the qualities of aerosol particles
When aerosol particles react with ammonia in the atmosphere their qualities can be altered.

For example, the capability of the aerosol particles to scatter light, to absorb moisture or to act as a cloud condensation nuclei can change. These changes can potentially alter the direct or indirect radiative forcing of the aersols, and thus, their impact on climate change.
