Xarray - multidimensional science data¶
This notebook reads aerosol index and Tropospheric $NO_{2}$ Concentration from Sentinel-5P TROPOMI data using Opengeo Tools
Tutorial data and code are from NASA ARSET program: https://appliedsciences.nasa.gov/join-mission/training/english/high-resolution-no2-monitoring-space-tropomi

Explore NetCDF file for its contents¶
The NetCDF file is like a folder with multiple sub-folders and files within it. Folders are called as groups and files within it are called as variables. NASA supplies a cross-platform app called Panoply which gives you a UI to query and visualize NetCDF files. Below is a screenshot of Panoply reading the Aerosol Index file.
The first step is to read this file as a netCDF4.Dataset class.
