Example of preliminary analysis and data exploration of Sentinel-5P satellite data

S5P-Analysis

This is the companion repository of s5p-tools. It shows how to download, preprocess and analyze Sentinel-5P data with Python.

Setting up

We recommend setting up a virtual environment with conda for easy management of external dependencies.

1. Clone the s5p-tools repository locally.

   git clone https://github.com/bilelomrani1/s5p-tools.git
   

2. Create a virtual environment named s5p with Python 3.7 and s5p-tools dependencies.

   conda create -n s5p python=3.7
   conda activate s5p
   conda config --add channels stcorp
   conda install -y -c stcorp -c conda-forge jupyterlab cartopy dask harp seaborn
   pip install -r s5p-tools/requirements.txt
   

Downloading data

We use the default script provided by s5p-tools to download and process data from Sentinel-5P. Here, we query the tropospheric column of NO2 over mainland France between 01/06/2020 and 08/06/2020. For more details on how to use s5p-tools, please refer to the README.

python s5p-tools/s5p-request.py L2__NO2___ --aoi geojson/france.geojson --date 20200601 20200608

Opening the notebook

1. Create a Jupyter server with

   jupyter lab
   

2. Open the notebook s5p-analysis.ipynb.

abstract = "Monitoring of air pollution is an important task in public health. Availability of data is often hindered by the paucity of the ground monitoring station network. We present here a new spatio-temporal dataset collected and processed from the Sentinel 5P remote sensing platform. As an example application, we applied the full workflow to process measurements of nitrogen dioxide (NO2) collected over the territory of mainland France from May 2018 to June 2019. The data stack generated is daily measurements at a 4 × 7 km spatial resolution. The supplementary Python code package used to collect and process the data is made publicly available. The dataset provided in this article is of value for policy-makers and health assessment."
