InSituMatched

The released InSituMatched dataset is divided by in-situ network and data split. Each file contains the same arrays and dimensions, but the number of matched samples differs.

Subset	Training samples	Testing samples
ABoVE	48	12
AmeriFlux	67	18
FLUXNET	68	16
ICOS-WW	9	4
Multiple-network sites	58	16

Variables

• ed_simulation_x — monthly ED input features at matched in-situ locations
• ed_simulation_y — age-specific ED simulation targets
• observed_y — in-situ GPP, RECO, and NEE observations
• lidar_age_weight_fraction — LiDAR-derived forest-age fractions
• esa_cci_bl_fraction — annual ESA CCI broadleaf PFT fractions
• esa_cci_nl_fraction — annual ESA CCI needleleaf PFT fractions
• esa_cci_gs_fraction — annual ESA CCI grass-and-shrub PFT fractions

The multiple subset contains sites occurring in more than one in-situ network.

All released arrays use sample-first orientation.
