Forest net primary productivity (NPP) constitutes a key flux within the terrestrial ecosystem carbon cycle and serves as a significant indicator of the forests carbon sequestration capacity, which is closely related to forest age. Despite its significance, the impact of forest age on NPP is often ...
Define net profit. net profit synonyms, net profit pronunciation, net profit translation, English dictionary definition of net profit. n gross profit minus all operating costs not included in the calculation of gross profit, esp wages, overheads, and dep
Net Primary Productivity (NPP) is the basis of the material and energy transport calculation in ecosystem studies. NPP directly reflects the production capacity of plant communities under natural conditions. Ecosystem services are hot topics in the field of ecology. Many studies calculate ecosystem serv...
In this study, the net primary productivity (NPP) in China from 2001 to 2012 was estimated based on the Carnegie-Ames-Stanford Approach (CASA) model using Moderate Resolution Imaging Spectroradiometer (MODIS) and meteorological datasets, and the accuracy was verified by a ChinaFLUX dataset. It was...
For the Sentinel-2 and the UAV data, the plots’ extends (24 × 24 m) were used as “regions of interest” to extract weighted mean reflectance values at each band for further calculation. The characteristics of the band used at each scale are summarized in Table 2. Table 2. Band ...
Now that you understand what is NPS, it is time for you to learn how to calculate the NPS. It is actually a very simple calculation. All you need to do is subtract the percentage of Detractors from the percentage of Promoters. The resulting score can range from -100 to +100. For exam...
