This dataset provides air negative oxygen ion concentration index data at 3-hour, 6-hour, and 12-hour intervals for the next three days, covering 72 grid points in Anji County, and is updated twice daily via rolling release. Based on refined grid forecasting technology, it delivers high-resolution air negative oxygen ion concentration index information tailored to users' actual locations. Users can directly utilize the data after retrieval, such as matching their current location to the nearest grid point.

This dataset can be applied to improving environmental quality, safeguarding public health, and optimizing tourism experiences, among other use cases. Negative (oxygen) ions are beneficial to physical and mental health: they can improve cardiopulmonary function, promote metabolism, and enhance the body's disease resistance, and are often referred to as "air vitamins", regarded as the primary factor supporting livable cities and communities.

The concentration of negative (oxygen) ions in the air varies with environmental conditions; they are relatively abundant in parks, suburban fields, coastal areas, lakes, near waterfalls, and forests. Currently, our county has carried out negative oxygen ion monitoring.

We automatically extract objective forecast products of intelligent grids covering the Anji area at 3-hour, 6-hour, and 12-hour intervals, establish a multiple linear statistical relationship between meteorological elements and the air negative oxygen ion concentration index, and automatically generate intelligent grid objective forecast products for the air negative oxygen ion concentration index at the aforementioned intervals after localizing the algorithm and rules for the air negative oxygen ion concentration index. The calculation formula is:
Negative Oxygen Ion Concentration = 50 + 150 × Average Wind Speed + 50 × UV Index - 5 × Relative Humidity + 20 × 3-hour Precipitation

According to the meteorological industry standard *Grade of Air Negative (Oxygen) Ion Concentration* (QX/T 380-2017), air freshness is divided into four levels based on the concentration of negative (oxygen) ions in the air:
1. Level 1: High negative oxygen ion concentration, fresh air, with concentration ≥ 1200 (particles/cm³);
2. Level 2: Relatively high negative oxygen ion concentration, relatively fresh air, with 500 ≤ concentration < 1200 (particles/cm³);
3. Level 3: Moderate negative oxygen ion concentration, average air quality, with 100 ≤ concentration < 500 (particles/cm³);
4. Level 4: Moderate negative oxygen ion concentration, average air quality, with 0 < concentration < 100 (particles/cm³).
