Jan 2024 - Jun 2024 (6 months)

To facilitate precise climate time series analysis for the environmental management plan in the construction project I perform data acquisition and preprocessing using python libraries such as Pandas and NumPy. I check for stationarity using statistical tests and conduct basic time series treatments, including analyzing the ENSO (El Niño-Southern Oscillation) component. I use Jupyter notebooks and libraries like Matplotlib and Seaborn for data visualization. Reviewing and validating the processed data help identify anomalies and trends, which are documented and integrated into the management plan.
