out
The folder where the image file will be written (i.e. /path/to/your/folder).
bbox Defines the bounding box in the form lat1,lon1,lat2,lon2, where each value is in decimal degrees. lat1 must be greater than lat2 and lon1 must be less than lon2 (i.e. the coordinate lat1,lon1 is the top left corner of the bounding box and lat2,lon2 is the bottom right corner).
username Your username for Copernicus Open Access Hub. Can be created here.

-m mission The mission to download images from. 1, 2, or 3. Defaults to 1.
