Accurate estimates of the spatiotemporal distribution evapotranspiration (ET) are essential for understanding terrestrial energy, carbon and water cycles. Station-based observations limited their spatial coverage whereas satellite-derived ET products exhibit large discrepancies uncertainties. Here we presented a Deep Neural Networks based Merging (DNN-MET) framework that combines information fr...

Estimating evapotranspiration (ET), the main water output flux within basins, is an important step in assessing hydrological changes and availability. However, direct measurements of ET are challenging, especially for large regions. Global products now provide gridded estimates at different temporal resolution, each with its own method estimating based on various data sources. This study invest...

Aging in leaves is characterized by a decrease in chlorophyll content and an accompanying loss of protein and ribonucleic acid. It is well known that these symptoms of senescence occur at an accelerated rate in excised mature leaves and in leaf discs floated on water. In recent years it has been established that several chemical substances retard the senescence of leaves. Among the compounds wh...

Context. Low-frequency radio arrays are opening a new window for the study of the sky, both to study new phenomena and to better characterize known source classes. Being flat-spectrum sources, blazars are so far poorly studied at low radio frequencies. Aims. We characterize the spectral properties of the blazar population at low radio frequency, compare the radio and high-energy properties of t...

Abstract For about half a century, the radio pulsar population was observed to spin in ∼0.002–12 s range, with different classes having spin-period evolution that differs substantially depending on their magnetic fields or past accretion history. The recent detection of several slowly rotating pulsars has reopened long-standing question exact physics, and observational biases, driving upper bou...

Abstract The growing use of global-scale environmental products in hydro-climatic modeling (with different assumptions, resolutions, and precisions) has increased the variety their applications complications uncertainties evaluations. Researchers have recently turned to statistical blending (fusion) these achieve optimal while avoiding difficulties. proposed this study includes five large-scale...

Currently available evapotranspiration (ET) products have not provided us with an accurate estimation for global irrigated land area. Thermal energy balance (EB) model has the potential to solve this problem. The of aerodynamic resistances is a major complication in most remote sensing ET models. An EB using column canopy-air turbulent heat diffusion method was developed more realistically depi...

Dyes plays an important role in our everyday life. From manufacturing plastics, paints, textile and even pills contain traces of dye used. With the ever-increasing demand for with growing world populations, use synthetic dyes has grown linearly. Bioremediation using microorganisms is on rise. The ability to accurately predict rate bioremediation relies upon gathering accurate decolourisation, w...

• Blue and green water fluxes were estimated from four remote sensing methods. Budyko SN methods should be applied with cautions for semiarid catchments. All show similar spatial distribution pattern of blue fluxes. Forested areas Mt. Kilimanjaro Meru consume up to 30 % water. EK method yields the most realistic results. Kikuletwa catchment, Upper Pangani River Basin, Tanzania. This study compa...

ABSTRACT Two recent discoveries, namely PSR J0901?4046 and GLEAM-X J162759.5?523504.3 (hereafter J1627), have corroborated an extant population of radio-loud periodic sources with long periods (76 1091 s, respectively) whose emission can hardly be explained by rotation losses. We argue that J1627 is a highly magnetized object consistent magnetar (an ultra-long period magnetar, ULPM), demonstrat...
