Second, you need to concatenate the bands of two aligned Sentinel-2 scenes that show your area of interest in two seasons (e.g. planting and harvesting seasons) in the following order: B04_t1, BO3_t1, BO2_t1, B08_t1, B04_t2, BO3_t2, BO2_t2, B08_t2 (t1 and t2 represent two different points in time). The `ftw inference download` command does this automatically given two STAC items. The Microsoft [Planetary Computer Explorer](https://planetarycomputer.microsoft.com/explore?d=sentinel-2-l2a) is a convenient tool for finding relevant scenes and their corresponding STAC items.

To select the timeframe for the two images (Window A and Window B), we looked at the [crop calendar](https://ipad.fas.usda.gov/ogamaps/cropcalendar.aspx) by USDA and found the approximate time for planting and harvesting. For example, if you open the crop calendar and select [China](https://ipad.fas.usda.gov/rssiws/al/crop_calendar/che.aspx), you will find that most of the crops are planted from Feb to May, and harvested from Aug to Nov. We then put these dates as filtering parameters in the planetary computer platform. Set the cloud threshold to 10% or less. Then select a clear observation that covers the full tile.
