大气中二氧化碳（CO2）的浓度正在增加，但鉴于我们目前对碳源和碳汇的了解，仍低于预期。据推测，陆地生物圈，特别是热带森林，是大气碳的主要汇。形成这些汇的一个可能机制是，在放弃以前砍伐的土地后，森林迅速再生。为了量化再生热带森林所吸收的碳量，需要有关其位置的数据，而且由于已知年轻的再生森林比老的再生森林生长得更快，吸收的碳更多，因此需要有关其年龄的数据。再生林的生物物理特性随年龄变化而变化，与周围成熟林不同。某些关键的生物物理特性可以被探测到，至少在原则上，使用卫星传感器数据记录在红色和近红外（NIR）波长。然而，尽管这种关系……
The concentration of carbon dioxide (CO2) in the atmosphere is increasing, but is still less than expected given our current knowledge of carbon sources and sinks. It has been hypothesised that the terrestrial biosphere in general and tropical forests in particular are acting as major sinks for atmospheric carbon. A possible mechanism for these sinks is the rapid regeneration of forests following the abandonment of previously cleared land. To quantify the amount of carbon sequestered by regenerating tropical forests requires data on their location and, since it is known that young regenerating forests grow faster and sequester more carbon than do old regenerating forests, data on their age. The biophysical properties of regenerating forests change with age and are different from those of the surrounding mature forests. Certain key biophysical properties can be detected, at least in principle, using satellite sensor data recorded in red and near infrared (NIR) wavelengths. However, while the relationship b...
