Highlights ► Remotely sensed vegetation indices correlated with crop biophysical parameters. ► GLAI and chlorophyll content of croplands correlated with soil respiration. ► Remotely sensed vegetation indices showed good relationships with soil respiration. ► It is possible to estimate...
Highlights ► Spatial spread predictions, e.g. fire or disease, are rarely objectively validated. ► We developed a method to assign landmarks to vector driven spread patterns. ► Landmark based methods can objectively assess spread predictions. ► Discrimination of error sources allows model...
Highlights ► 515 Scots pine ring width samples were collected at three Carpathian cliff sites. ► An ensemble approach of 3240 growth–climate interactions was applied. ► Hydroclimatic sensitivity of pine growth revealed spatiotemporal inconsistency. ► Orographic-induced climatology...
Highlights ► We study image-related influences on the LAI estimation from hemispherical images. ► These are the radiometric image resolution, file format and image band selection. ► The latter two affect the LAI estimation and hamper the determination of optimum exposure. ► We develop an...
Highlights ► Sap flow methods do not accurately determine thermal diffusivity. ► Inaccurate determination of diffusivity leads to inaccurate sap flow measurements. ► A new method and sensor are proposed to accurately determine diffusivity.
Highlights ► We studied the seasonal patterns in leaf reflectance, photosynthesis and color in two tree species. ► We aimed at elucidating the interdependence of drivers of large-scale remotely sensed signals. ► Spectral indices accurately reflected leaf physiology and model parameters...
Highlights ► Forced cuttings were tested as data source for calibrating grape budburst models. ► Calibration on forced cuttings was more consistent than that based on field data. ► Despite that, both calibration approaches provided comparable estimates accuracy. ► They however diverged...
Highlights ► MSG radiation estimates are accurate and unbiased compared with flux tower measurements. ► Quality of MSG radiation estimates is uniform over Europe. ► Gridded MSG radiation is consistent with ERA-INTERIM but superior to gridded station data. ► Impact on crop simulation...
Highlights ► Developed semi-analytic multi-layer model to predict gap probability and radiation transfer in clumped canopies. ► Analytic approximation to the crown porosity: computationally efficient and demonstrated validity. ► Applied to complex canopy structures. ► Can be formulated in...
