Alt Description ΔAGB Bias Accuracy Precision r
1 90 m C-band SRTM as reference DSM, AGB model calibrated only in 2010 12.1 -2.6 65 65 0.66
2 30 m X-band SRTM as reference DSM, AGB model calibrated only in 2010 20.4 5.7 59 59 0.73
3 90 m C-band SRTM as reference DSM, AGB calibrated with separate models in 2000 and 2010 21.9 7.2 63 63 0.67
4 30 m X-band SRTM as reference DSM, AGB calibrated with separate models in 2000 and 2010 19.0 4.3 59 59 0.73

Field measured ΔAGB was used as the reference with a mean value of 14.7 t/ha.
