This work presents a parametric-solver algorithm for estimating atmospheric stability and friction velocity from floating Doppler wind lidar (FDWL) observations close to the mast of IJmuiden in North Sea. The focus study was two-fold: (i) examine sensitivity computational retrieved variables derived classes (the latter through confusion-matrix theory), (ii) present data screening procedures FDW...

Precipitation nowcasting is an important tool for economic and social services, especially forecasting severe weather. The crucial challenging part of radar echo image prediction the focus radar-based precipitation nowcasting. Recently, a number deep learning models have been designed to solve problem extrapolating images. Although these methods can generate better results than traditional extr...

The ‘Living Planet Programme’ of the European Space Agency (ESA) is gaining momentum. Six Earth Explorer missions are currently being implemented including ADM-Aeolus, ESA’s Doppler Wind LIDAR (DWL) mission. The Aeolus mission will demonstrate the capability of a space-borne high spectral resolution DWL to accurately measure wind profiles in the troposphere and the lower stratosphere (0-30 km)....

Parental lines, namely: F1, F2, BC1, BC2, BC11, BC12, BC21, BC22, BC1 selfed, and BC2 selfed generations of three crosses involving six cultivars of durum wheat (Triticum durum Desf.) were studied for awn length under normaland late-sown environments to analyze the nature of gene effects and components of heterosis (over the better parent). A sixparameter model in the cross Cocorit 71 x A-9-30-...

Abstract. The realization of the European Space Agency's Aeolus mission was supported by long-standing development and field deployment Atmospheric LAser Doppler INstrument (ALADIN) Airborne Demonstrator (A2D) which, since launch satellite in 2018, has been serving as a key instrument for validation ALADIN, first-ever wind lidar (DWL) space. However, capabilities A2D are compromised deficiencie...

Abstract. Since the start of European Space Agency's Aeolus mission in 2018, various studies were dedicated to evaluation its wind data quality and particularly determination systematic random errors Rayleigh-clear Mie-cloudy results provided Level-2B (L2B) product. The control (QC) schemes applied analyses mostly rely on estimated error (EE), reported L2B data, using different often subjective...

According to the European Directives (UE) 2020/2184 and 2009/54/EC, which establishes sanitary criteria for water intended human consumption in Europe, suitable must be free of bacterial indicators Escherichia coli, Clostridium perfringens Enterococcus spp. Drinking is also monitored heterotrophic bacteria, are not a health risk, but can serve as an index bacteriological quality. Therefore, rap...

There are two criteria by which economists measure the outcomes of tax policy: 1. E¢ ciency, which is traditionally the purview of economics, and does not involve ethical and normative judgments. E¢ ciency considers only how resources are allocated 2. Equity, which considers the distribution of resources. We will need to refer to social norms and value judgments to get conclusions based on this...
