Species driving New Rochelle’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 38 (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.

This month sits outside the usual ragweed pollen window for the Northeast pattern, so today’s ragweed pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first.
