A new approach for estimating northern peatland gross primary productivity using a satellite-sensor-derived chlorophyll index

, 2011
Carbon flux models that are largely driven by remotely sensed data can be used to estimate gross primary productivity (GPP) over large areas, but despite the importance of peatland ecosystems in the global carbon cycle, relatively little attention has ...

Improving model estimates of gross primary production [PDF]

Eos, Transactions American Geophysical Union, 2011
Balancing the global carbon budget is a daunting task complicated by the fact that even the most essential values elude direct observation. Gross primary production, the amount of carbon used by terrestrial vegetation to fuel its annual growth, is often estimated by extrapolation from observations using climate models, including the Community Land ...

Annual Gross Primary Production from Vegetation Indices: A Theoretically Sound Approach

Remote Sensing, 2017
A linear relationship between the annual gross primary production (GPP) and a PAR-weighted vegetation index is theoretically derived from the Monteith equation.

Clinical performance of the urine‐based TERT promoter AbsoluteQ Digital PCR for non‐invasive detection of bladder cancer

Molecular Oncology, EarlyView.
A urine‐based digital PCR assay targeting two hotspot TERT promoter variants detected bladder cancer with high sensitivity and no false positives in this case–control cohort. The streamlined AbsoluteQ workflow outperformed Sanger sequencing and supports non‐invasive molecular testing for bladder cancer detection.

Development and Extrapolation of a General Light Use Efficiency Model for the Gross Primary Production [PDF]

, 2011
The global carbon cycle is one of the large biogeochemical cycles spanning all living and non-living compartments of the Earth system. Against the background of accelerating global change, the scientific community is highly interested in analyzing and ...

Evidence for strong seasonality in the carbon storage and carbon use efficiency of an Amazonian forest [PDF]

, 2014
The relative contribution of gross primary production and ecosystem respiration to seasonal changes in the net carbon flux of tropical forests remains poorly quantified by both modelling and field studies.
