Despite their importance, there is currently a lack of an accurate, long-term, high-resolution national cooking emission inventory in China, primarily due to the challenges in obtaining high-quality activity level data over extended periods and at fine spatial scales. Here, we address these limitations by leveraging advanced machine learning techniques to predict activity levels and further estimate emissions.
