In the last part of the Tutorial, you will create a temporary averaged NO₂ map using "wildcards". In Python, wildcards are a symbol used to replace or represent one or more characters - e.g. an asterics (*) which is used to specify any number of characters. This lets you apply a function to multiple files.

For this tutorial you will complete the following three steps:

• Import all Sentinel-5p NO₂ Level 2 data and regrid into a common grid by applying relevent operations
• Create a temporally averaged merged product by applying 'reduce_operations()' to the 'harp.import_product()' function
• Plot with Visan using 'wplot()' function
