Evaluation of the METRIC and TSEB remote sensing evapotranspiration models in the floodplain area of the Thaya and Morava Rivers.
Verze 2      

Popis: The attached file contains 7 graphs related to the study:
Study region: Floodplain ecosystem region at the confluence of the Morava and Thaya Rivers, the Czech Republic.
Study focus: Accurate determination of actual evapotranspiration (ETa) is essential for understanding surface hydrological conditions. The aim of this study was to evaluate two remote sensing models, METRIC and TSEB, for estimating ETa and energy fluxes in two ecosystems using the eddy covariance (EC) as a reference.
New hydrological insights for the region: Both models demonstrate the ability to quantify ETa across the region. Compared with the METRIC, which had a mean bias error (MBE) = 0.12 mm/day, the TSEB better detected ETa in the forest test site (MBETSEB = -0.03 mm/day). In contrast, the METRIC improved detection of ETa (MBEMETRIC = -0.03 mm/day) in grassland test site, where the TSEB overestimate daily ETa (MBETSEB = 0.52 mm/day). The models and EC indicate similar seasonal dynamics of the evaporative fraction and Bowen ratio throughout the growing season. Despite the overall agreement between the models and EC, the selected spatial outputs indicate some disagreement among them in terms of the spatial patterns of ETa. This disagreement is related to the sensitivity of TSEB to canopy height/roughness, as well as the a priori Priestley–Taylor coefficient in forests. Despite these shortcomings, this study highlights the applicability of remote sensing energy balance-based diagnostic models for studying hydrological processes in a spatially distributed manner.
This deposit contains 6 .xlsx files.

Files 1–4 represent a combination of outputs from available models (TSEB, METRIC) and eddy covariance measurements for specific ecosystems (grassland, forest) during the period 2015–2021. These files contain energy balance and evapotranspiration data, including the Bowen ratio and evaporation fraction derived from eddy covariance measurements.

Files 5 and 6 contain measured daily eddy covariance evapotranspiration data and interpolated daily model data for the period 2015–2021 in grassland and forest ecosystems. These files are supplemented with directly available clear-sky evapotranspiration data from the TSEB and METRIC models.

Thin hydrogenated amorphous silicon carbide layers with embedded Ge nanocrystals.

Popis: The in-situ combination of plasma-enhanced chemical vapor deposition (PECVD) and vacuum evaporation in a vacuum chamber allowed us to integrate germanium nanocrystals (Ge NCs) into hydrogenated amorphous silicon carbide (a-SiC:H) thin films deposited from monomethyl silane diluted with hydrogen. Transmission electron microscopy (TEM) and energy-dispersive X-ray (EDX) spectroscopy were used for the microscopic characterization of the thin films, while photothermal deflection spectroscopy (PDS) and near-infrared photoluminescence spectroscopy (NIR PL) were used for their optical characterization. The presence of Ge NCs embedded in the amorphous a-Si:C:H was confirmed by TEM and EDX. The Ge NCs embedded in a-SiC:H layers in-creased optical absorption in the NIR spectral region. The quenching of a-SiC:H NIR PL due to the presence of Ge indicates that the diffusion length of free charge carriers in a-SiC:H is in the range 10-30 nm, an order of magnitude less than in a-Si:H. The optical properties of a-SiC:H films were degraded after vacuum annealing at 550 C.
