In this exercise, I learned to automate a download for each image from a collection as a GeoTIFF file for further processing.

My workflow out is described below:

1. Create and filter an image collection
2. Run a "for loop" on your image collection
3. Use ee.batch.Export to run the batch export after defining your filtered images
4. Start the task

See the demo link below to review and run my script for 12 images of average max surface temperature across Australia per month.
