Goal of the competition

In this challenge, the competitors' goal was to build a model to predict the yearly Aboveground Biomass (AGBM) for 2,560 x 2,560 meter patches of Finnish forests using satellite imagery from Sentinel-1 (S1) and Sentinel-2 (S2). AGBM is a widespread metric for the study of carbon release and sequestration by forests and is used by forest owners, policymakers, and conservationists to make decisions about forest management.

Winning submissions

Place	User	Private Score	Summary of Model
1	kbrodt	27.63	Combined S1 and S2 images into a 15-band 12-month composite, used a UNET model with test time augmentation.
2	Team Just4Fun: qqggg, HongweiFan	27.68	Used a SWIN UNETR model adopted from the Medical Open Network for AI on satellite features represented in 3D.
3	yurithefury	28.04	Aggregated S1 and S2 data into 6 median composites per year, ensembled together 15 models using UNET++ architecture.
MATLAB Bonus Prize	Team D_R_K_A: kaveh9877, AZK90	31.08	Combined S1 and S2 images into a 15-band 12-month composite, used a 1-D CNN to perform by-pixel regression. The resulting labels were added as a 16th band to the composites, which were then passed through a 3-D U-Net model.

Additional solution details can be found in the reports folder inside the directory for each submission.
