wass2s 0.1.10

A Python package for seasonal climate forecast.

wass2s: A python-based tool for seasonal climate forecast

wass2s is a comprehensive tool developed to enhance the accuracy and reproducibility of seasonal forecasts in West Africa and the Sahel. This initiative aligns with the World Meteorological Organization's (WMO) guidelines for objective, operational, and scientifically rigorous seasonal forecasting methods.

Overview

The wass2s tool is designed to facilitate the generation of seasonal forecasts using various statistical and machine learning methods including the Exploration of AI methods. It helps forecaster to download data, build models, verify the models, and forecast. A user-friendly jupyter-lab notebook streaming the process of prevision.

🚀 Features

• ✅ Automated Forecasting: Streamlines the seasonal forecasting process, reducing manual interventions.
• 🔄 Reproducibility: Ensures that forecasts can be consistently reproduced and evaluated.
• 📊 Modularity: Highly modular tool. Users can easily customize and extend the tool to meet their specific needs.
• 🤖 Exploration of AI and Machine Learning: Investigates the use of advanced technologies to further improve forecasting accuracy.

📥 Installation

1. Download and Install miniconda

• For Windows, download the executable here

• For Linux (Ubuntu), in the terminal run:

  sudo apt-get update
  sudo apt-get upgrade
  sudo apt-get install wget
  wget -c -r https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh --no-check-certificate
  bash Miniconda3-latest-Linux-x86_64.sh
  

2. Create an environment and activate

• For Windows: download yaml here and run

conda env create -f WAS_S2S_windows.yml
conda activate WASS2S

• For Linux: download yaml here and run

conda env create -f WAS_S2S_linux.yml
conda activate WASS2S

3. Install wass2s

pip install wass2s

4. Download notebooks for simulation

git clone https://github.com/hmandela/WASS2S_notebooks.git

5. Create CDS API key and use it to download NMME and C3S models data from the Climate Data Store (CDS) and IRI Data Library.

• Create an account with Copernicus by signing up here

• Once you successfully create an account, kindly log in to your Copernicus account and click on your name at the top right corner of the page. Note your "UID" and "Personal Access Token key".

• Configure .cdsapirc file.

In your activated terminal, kindly initiate the Python interpreter by entering the command python3. Subsequently, carefully copy and paste the below code, ensuring to replace "Personal Access Token" with yours.

import os

config_data = '''url: https://cds.climate.copernicus.eu/api
key: Personal Access Token
verify: 0
'''

path_to_home = "/".join([os.path.expanduser('~'),".cdsapirc"])

if not os.path.exists(path_to_home):
    with open(path_to_home, 'w') as file:
        file.write(config_data)
        
print("Configuration file created successfully!")

Upgrade wass2s

If you want to upgrade wass2s to a newer version, use the following command:

pip install --upgrade wass2s
