dmytrobuhai/ukrainian_air_quality_daily_pollution_in_wartime

This dataset presents daily measurements of air pollution across more than 35 Ukrainian cities during the years 2024–2025, collected from official open government sources. Each row represents a specific measurement of an air pollutant (e.g., sulfur dioxide, ammonia, soot) in a given city on a particular day.

To enrich the contextual dimension of this dataset, we included open-source incident data on civilian harm resulting from missile and drone strikes.

#🟢 Tasks Using Pollution Data (pollution_dataset.csv)

• 1️⃣ Time Series Forecasting: Air Pollution Prediction
• 2️⃣ Anomaly Detection in Air Quality (Detect unusual pollution spikes that deviate from normal patterns)
• 3️⃣ Clustering of Cities by Pollution Profiles

#🔴 Tasks Using Civilian Harm Data (ukr_harm.csv)

• 4️⃣ NLP: Attack Event Categorization (Classify attack descriptions into predefined categories)
• 5️⃣ Location-Based Risk Modeling (Assess the likelihood of future attacks in specific cities based on past trends)

#🟡 Tasks Using Both Datasets Together

• 6️⃣ Impact of War on Air Quality
• 7️⃣ Predicting Civilian Harm from Air Pollution Data
• 8️⃣ Spatio-Temporal Heatmaps of Pollution and Attacks

🔍 Data Cleaning & Standardization

Geolocation data was removed from ukr_harm.csv to protect privacy. Non-essential metadata was excluded. City names were standardized to match available locations in pollution_dataset.csv.
