General description of the script
Monthly composite (31 days before the chosen date), computed with best bands ratio. This script is here for those who want a cloud free image representing the last 31 days.
In order to select the best pixel in a month (and avoid cloud), a selection is made using a ratio :
- When blue < 0.12, date is chosen where max ratio of B08 against B02.
- If no pixel available above, when blue < 0.45, date is chosen where max ratio of B03 against B02.
- If water is detected, date is chosen where max ratio of B02 against B08.
- If snow is detected, median of scene with snow.
