MeteoGalicia-Application

README Version in Spanish/Castilian (versión en español/castellano)

Overview

This application processes meteorological data (from 2007 to present) from MeteoGalicia, a regional meteorological agency in Galicia, Spain. MeteoGalicia provides weather forecasts, climate data, and environmental monitoring for the region. It also offers historical records of various meteorological variables such as temperature, precipitation, solar radiation, and wind speed.

The application allows users to convert, analyze, and visualize historical weather data efficiently. It includes a user-friendly GUI for easy interaction and data conversion scripts to transform CSV files into ODS spreadsheets. Users can also generate graphs based on meteorological trends, making it a valuable tool for researchers, analysts, and weather enthusiasts working with historical climate data.

Recent Changes

As of 2025, MeteoGalicia has updated its website and changed the format of its CSV data output. Currently, this application does not work with the new CSV format but remains functional with older CSV files.

Features

• User-Friendly GUI: The graphical interface allows users to browse and select input files, convert data, and generate graphs effortlessly.
• Data Conversion: Converts CSV files into human-readable ODS spreadsheets by reorganizing and processing meteorological data.
• Graph Generation: Users can visualize yearly meteorological trends in an easy-to-read bar chart.
• Dark Mode & Language Switching: Toggle between light/dark mode and switch between English and Spanish.
• Standalone Executable Available: No setup required; just run the .exe file (see below).

Installation & Usage

Option 1: Run the Standalone Executable (Recommended)

• Download the executable Aplicación - Proyecto de Información Meteorológica.exe from the repository.
• Ensure the _internal folder is in the same directory (included in the GitHub repo).
• Run the .exe file, and the GUI will launch.

Option 2: Run the Python Script

If you prefer to run the script manually:

1. Clone the Repository:

   git clone https://github.com/yourusername/MeteoGalicia-Application.git
   cd MeteoGalicia-Application
   

2. Install Dependencies:

   pip install -r requirements.txt
   

3. Run the Application:

   python gui.py
   

How to Use

1. Obtain a CSV File (from older MeteoGalicia data):

   • Visit MeteoGalicia.
   • Select "Variables mensuales", choose a variable, and specify a date range.
   • Click "CONSULTAR" and then download "Resultados en formato CSV en columnas".
   • This CSV file is your input file.

2. Convert the CSV to ODS:

   • Open the application.
   • Select the CSV file as the input.
   • Click "Create ODS File" to generate a processed spreadsheet.

Example ODS Conversion:

Dependencies

The following Python packages are required (installed via requirements.txt):

• pandas
• pyexcel_ods3
• numpy
• matplotlib
• tkinter

Notes

• This application does NOT support MeteoGalicia's new 2025 CSV format. If you encounter issues, try using older data files.
• If using the standalone executable, ensure the _internal folder is in the same directory.
• The graphs provide insights into historical weather trends but may require additional preprocessing for compatibility with future data formats.
