Species driving Calabasas’s ragweed pollen

Species-level counts are not part of the modelled data Pollen Atlas publishes — the modelled index is reported per pollen type, not per species — so this section gives the type summary: ragweed pollen reads 23 (Low) today. The plant-by-plant detail that is available, from the Google Pollen API, is in the next section.

How to read this: the “ragweed” figure on this site is the modelled weed pollen index — the weed group (ragweed + mugwort) — printed under the ragweed name the rankings use.
