a global scale. Products are Gross Primary Production (GPP), Net Primary Production (NPP). It is based on a modified version of the Farquhar approach (Haxeltine and Prentice 1996, Farquhar et al. 1980). Where possible, it uses vectorization and parallelization and dynamically downloads latest ...
The MOD17A2H V6 Gross Primary Productivity (GPP) product is a cumulative 8-day composite with a 500m resolution. The product is based on the radiation-use efficiency concept and can be potentially used as inputs to data models to calculate terrestrial energy, carbon, water cycle processes, an...
GCOM-C SGLI land products are being developed toward better understandings of terrestrial carbon cycle and future climate change projection. In this paper, we will introduce two research products, Leaf Area Index (LAI) and Net Primary Productivity (NPP) and their application of these products to...
in Fenno-Scandia as a case study, we investigate whether net primary production (NPP) and maintenance respiration are constant fractions of gross primary production (GPP) as even-aged mono-specific stands progress from initiation to old age. A model of the ratio of NPP to GPP is...
GPP is integrated over the growing season to estimate Net Primary Production (NPP). Growth and maintenance respiration costs for NPP are either accounted for indirectly, e.g. Carnegie-Ames-Stanford Approach (CASA: Potter et al., 1993) and the Moderate Resolution Imaging Spectroradiometer GPP/NPP ...
[20] evaluated landscape variability in soil-water-plant relations and net primary production (NPP) in tall grass prairie and found that NPP was linearly related with soil water content along two transects (R2 = 0.66). Reynolds et al. [21] studied the relationship between rainfall, soil ...
The MOD17 algorithm uses the radiation-use efficiency concept first proposed by Monteith [3] and provides a method for estimating pixel-wise GPP and Net Primary Productivity (NPP) globally [5]. Satellite-derived GPP, such as from MODIS, is useful because it helps model terrestrial energy, ...
Detailed biometric data can be used to estimate Net Primary Productivity (NPP), i.e., the amount of C fixed by GPP after excluding autotrophic respiration [39]. Such data can also be integrated with photosynthetic and respiration measurements, to ultimately infer GPP and NEP [40]. In this ...
