The RRI, R80P, and YrYr metrics are based on approaches\ndescribed by Frazier et al. (2018)\n. Threshold-based recovery-time\napproaches have been used to quantify post-fire vegetation\nrecovery from spectral time series by Chompuchan and Lin (2017)\n. Exponential recovery\nformulations have also been applied to post-fire vegetation\ntime series by Gouveia et al. (2010)\n. Parametric recovery models,\nincluding exponential, logistic, and Gompertz formulations, are\nprovided to characterize nonlinear post-disturbance recovery\ntrajectories.", "License": "GPL-3",
