There are 10 granules at <= 5% cloud cover There are 7 granules at 0% cloud cover

I chose the 10 granules at <= 5% cloud cover to download. Here is my search query url

Downloading the data

• Use step1_download_hls.sh to download all the granules. This will download all the files into the directory you run the script from. This script is a copy/paste from the EarthData website.
• Next, use step2_organize_granules.py to place all of the downloaded granules into a directory structure that is easier to work with. Each directory is unique based on the granule and the date.

After running step2_organize_granules.py, your directory should look like this*

• The current version puts all the granules into a 'granules' directory

Mosaic granules

 sh step3_mosaic_granule_bands.sh

This will mosaic all the bands for each granule into a single file. The output will be in the same directory as the granule. The output file will be named '<granule_name>_mosaic.tif'

Let's check to make sure the mosaics look good. We can use gdalinfo to check the metadata of the mosaic.

 gdalinfo granules/<granule_name>/<granuel_name>_mosaic.tif
> Band 1
> Band 2
> Band 3
> Band N
