Table 6 Summary of the correlations between AGB and the backscatter of HV polarization

From: Time-series maps of aboveground biomass in dipterocarps forests of Malaysia from PALSAR and PALSAR-2 polarimetric data

Year Sensor Prediction equation R2 Number of samples (n) RMSE
(Mg ha−1)
2010 PALSAR y = 2182.9e0.1442x 0.2735 254 115.89
2016 PALSAR-2 y = 8665e0.2535x 0.5581 80 117.45
2010 and 2016 PALSAR+PALSAR-2 y = 3166.7e0.1744x 0.3541 334 116.91
  1. Backscatter is in gamma naught (γ°, dB) and AGB in (Mg ha − 1). All correlations are significant at p < 0.05
