Fictional example: Zoe compares two index screenshots for a local report. They concern different days. She dates them before comparing and separately looks for pollen information, without treating the index as a measurement of personal exposure.
Your useful record: Territory, day, displayed category and source organization.
A background index does not measure individual exposure in every street.
