Methodological steps:

1) Extract_data.py: loads point-specific data (FFEM-DB-points.xlsx), removes duplicate records based on date, latitude and longitude. Based on the year of each data point, the script selects the MSWEP dataset (https://www.gloh2o.org/mswep/). For each data point: extracts a spatial area around the latitude and longitute (±0.15 degrees) and a time range from 75hours before to 50 hours after the given data, creating a 5 days temporal window. For each point it saves a new NetCDF file named after the point ID and country.

2) Max_rolling_R.py: Opens each NetCDF file, calculating rolling sums of precipitation over 3, 6, 12, 24, 48 hours. Determines the maximum precipitation value for each rolling sum. Saves the calculated maximum values in a Dataframe and exports it to an excel file. Merges the precipitation data with the external dataset (points.xlsx) based on the id column. Saves the merged dataset to excel file (floods_mswep_merge.xlsx). 

3) Fill_blanks.py: It reads the floods_mswep_merge.xlsx, gerates a unique identifier for each row based on latitude, longitude and country and then fills missing values in specific columns ('Max3h', 'Max6h' etc) with the maximum values for each unique identifier. It then saves the updated data to the final xlsx file (filled_floods_mswep_merged.xlsx).
