摘要: We examined the usability of daily green–red vegetation index (GRVI) observations from Terra and Aqua Moderate Resolution Imaging Spectroradiometer satellite on cloud-free days for monitoring ecosystem changes in Bornean tropical forests at a 500 m spatial resolution over 11 years (2003–2013). The number observational GRVI data southwest monsoon period (May–October; 1–5 days/month) was greater than that northeast (November–April; 0–2 days/month). Spatial variation observation frequency noticed, with (morning) (afternoon) showing different geographic distribution patterns data. western Kalimantan mountains (Sarawak Sabah) 1–2 days/month eastern (Kalimantan). quality validated by using sky images taken same time as canopy surface rainforest.
