Track and Trace

Track and Trace

The emerging cloud seeding communities use small amounts of organic dye to tag their cloud seeding attempts. The dye is dispersed with the condensation nuclei and trace amounts are thus contained in the resulting water droplets. Members of the weather modification community analyse precipitates under a microscope to record the provenance of a given cloud formation.
Once collated this data provides useful information about the effectiveness of the cloud seeding, broader weather systems and the source of the rain fall. Location colours are assigned by local football team, for example Leicester modifiers insert Indigo Carmine (blue) and Nottingham uses Malachite (green).
