In this example, a multilayer perceptron-based data imputation model is employed to simulate the missing air quality data at the monitoring station based on the air quality data of the neighboring stations. The dataset used in this study were downloaded from the air quality database of Hong ...

Download the AQI Dataset and put its content in the directory AQI-Attention-based-DNN/data/ Test With Different Models ADNNet.ipynb and ADNNet_multisteps.ipynb represent the implementation of one-step prediction and multi-step prediction respectively. --baseline: LSTM, N-BEATS, Informer, Autoform...
The Hot Spot Analysis calculates the Getis-Ord Gi* statistic for each city in a dataset. By definition, Gi* is calculated as follows (Getis and Ord, 1992):(2)where wi,j is the spatial weight between city i and city j; x, n, and \(\overline{x}\) have the same meanings as in ...
Existing methods for fine-scale air quality assessment have significant gaps in their reliability. Purely data-driven methods lack any physically-based mechanisms to simulate the interactive process of air pollution, potentially leading to physically inc
However, it should be emphasized that the number of Very Unhealthy hours for Kragujevac was less than 10 (2‰ of the testing dataset). In contrast to Kragujevac and Skopje, the precision of air quality classifications improved for Lahore as PM2.5 concentrations increased from first to second ...
The ERA5 reanalysis data were downloaded from https://www.ecmwf.int/en/forecasts/dataset/ecmwf-reanalysis-v5. The AURA OMI/MLS tropospheric O3 column was downloaded from https://acd-ext.gsfc.nasa.gov/Data_services/cloud_slice/new_data.html. The total O3 column of SBUV Merged Ozone Data ...
The air quality changes in these cities were further examined using a ground-level air quality dataset made available by pollution monitoring institutions. 2.2.2. AQI/IP data and instrumentation For an in-depth analysis of air quality changes in these cities, the air quality index (AQI) and ...
