Evaluation of the MERIS terrestrial chlorophyll index (MTCI)
Advances in Space Research, 2007The medium resolution imaging spectrometer (MERIS), one of the payloads on Envisat, has fine spectral resolution, moderate spatial resolution and a three day repeat cycle. This makes MERIS a potentially valuable sensor for the measurement and monitoring of terrestrial environments at regional to global scales. The red edge, which results from an abrupt

Global composites of the MERIS Terrestrial Chlorophyll Index
International Journal of Remote Sensing, 2007From the year 2006, the European Space Agency (ESA) supported the production of the global composite (Level 3) of a unique terrestrial chlorophyll product called the MERIS Terrestrial Chlorophyll I...

Solar-induced chlorophyll (chl) fluorescence (SIF) has been shown to be positively correlated with vegetation photosynthesis, suggesting that it is a useful signal for understanding of environmental responses and spatial heterogeneity of photosynthetic activity at various scales from leaf to the globe.

Remote sensing techniques can offer powerful tools for measuring concentrations of chlorophyll-a chl-a, which is an important proxy for water quality. However, remote estimates of chl-a can be difficult in water bodies that have high levels of total suspended matter TSM.

Remote Sensing for Agriculture, Ecosystems, and Hydrology XXI, 2019
We present an algorithm for estimating gross primary production (GPP) capacity based on chlorophyll indexes and light-response curves. Leaf chlorophyll content is a major determinant of GPP capacity. The initial slope of light-response curves and maximum GPP capacity under light saturation were determined using flux and Moderate Resolution Imaging ...

Chlorophyll a concentration as an index of sediment surface stabilisation by microphytobenthos?
Continental Shelf Research, 2000In this study the potential of predicting critical erosion shear stresses from microphytobenthos chlorophyll a surface concentrations in the upper mm of the sediment surface was investigated. The results should provide a better basis for estimating sediment surface stability on large scales by means of optical remote sensing. To achieve a comprehensive

Heat stability of chlorophyll as an index of adaptation for overwintering
Biochemie und Physiologie der Pflanzen, 1970Summary The difference between the percentages of transmission of chlorophyll extracts from the heated and unheated samples of green tissues, recorded at 640 m µ , constitutes the “chlorophyll index”. The relative stability (or the lack of it) of this index over a period of time appears to be a dependable criterion of adaptation for over-wintering ...

Structure-resistant Chlorophyll Index: A Novel Indicator for Leaf Chlorophyll Content Monitoring
Leaf Chlorophyll Content (LCC) serves as an indicator of vegetation photosynthetic capacity. The quick and accurate characterization of LCC is essential for assessing vegetation productivity and carbon sequestration capacities. Remote sensing technology provides various indicators that are important tools for large-scale LCC monitoring.Jinhua Li +8 more

Estimation of Chlorophyll Concentration Index at Leaves using Artificial Neural Networks
Journal of Circuits, Systems and Computers, 2016In this study, the effectiveness of an SPAD-502 portable chlorophyll (Chl) meter was evaluated for estimating the Chl contents in leaves of some medicinal and aromatic plants. To predict the individual chlorophyll concentration indexes of St. John’s wort (Hypericum perforatum L.), mint (Mentha angustifolia L.), melissa (Melissa officinalis L.), thyme (

The MERIS terrestrial chlorophyll index [PDF]
, 2005 This thesis reports on the design, evaluation and application of a surrogate REP index for use with spectral data recorded at the standard band settings of the Medium Resolution Imaging Spectrometer (MERIS). This index, termed the MERIS terrestrial chlorophyll index (MTCI) uses data in three red and NIR wavebands centred at 681.25 nm, 708.75 nm and ...
