GEE AOD Validation and Data Processing( only fix the code).

Project overview
Assist in debugging and enhancing a GEE script for accurate AOD data analysis and validation using MODIS and AERONET data over Saudi Arabia.

Data needs
- Process MODIS MAIAC (MCD19A2) daily AOD data at 550 nm specifically for Saudi Arabia.
- Validate against AERONET AOD Level 2.0 data from June, July, and August 2023 at the KAUST Campus station.
- Ensure temporal (±30 minutes) and spatial (10 km × 10 km and 25 km × 25 km windows) alignment of MODIS and AERONET data.
- Interpolate AERONET AOD at 550 nm using the Ångström exponent and available bands.
- Calculate statistical metrics: Pearson correlation, Mean Bias Error (MBE), and Root Mean Square Error (RMSE).


Additional information
- Access to the existing code will be provided for debugging and fixing.
