Even though the contribution of aviation sector to global economy is very notable, it also has an adverse impact on climate change. Improvements have been made in different areas (i.e., technology, sustainable fuel, and design) mitigate these effects. However, rate improvement small compared increase demand for air transportation. Hence, greenhouse gas emissions are steadily increasing this trend expected continue unless adequately addressed. In context, study examined following: (i) factors...
In September 2014, Kashmir witnessed a catastrophic flood resulting in significant loss of lives and property. Such massive losses could have been avoided if any structural support such as dams were constructed the Jhelum basin, which has history devastating floods. The GIS-based multicriteria analysis (MCA) model provided three suitability zones for dam locations. final suitable sites identified within highest zone based on topography (cross-sections), stream order, high zone, minimum site...
Large-scale debris cover glacier mapping can be efficiently conducted from high spatial resolution (HSR) remote sensing imagery using object-based image analysis (OBIA), which works on a group of pixels. This paper presents the spectral and capabilities OBIA to classify multiple classes multisource approach by integrating multispectral, thermal, slope information into one workflow. The novel contributions this study are effective small yet important geomorphological features, classification...
Water scarcity is a global challenge, especially in arid regions, including Middle Eastern and North African countries. The distribution of water around the earth not even. Trading form an embedded commodity, known as footprint (WF), from water-abundant regions to water-scarce viable solution problems. Agricultural products account for approximately 85% earth’s total WF, indicating that importing water-intense crops, such cereal can partially solve local problem. This study investigated...
An optical algorithm is developed for the retrieval of downwelling diffuse attenuation coefficient K <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">d</sub> (490) in Red Sea using a comprehensive hydrolight simulated data set (N = 5000). We found robust relationship between and ratio remote sensing reflectance Rrs(443)/R xmlns:xlink="http://www.w3.org/1999/xlink">rs</sub> (555), with an excellent determination (R <sup...
The study evaluates the impacts of India’s COVID-19 lockdown and unlocking periods on country’s ambient air quality. India experienced three strictly enforced lockdowns followed by where economic social restrictions were gradually lifted. We have examined in situ satellite data NO2 emissions for several Indian cities to assess India. Additionally, we analyzed acquired from Sentinel-5P TROPOMI sensor over a few districts Punjab state, as well National Capital Region. comparisons between...
Previous success in improving the CO2 capacity of physical solvents for pre-combustion carbon capture by imparting poly(ethylene glycol) (PEG) functionality led us to compare tributyl phosphate (TBP), tri-isobutyl (TiBP) and three analogous organophosphate which length PEG-substitution was varied. The PEG-substituted proved have acceptable densities viscosities application interest, but all showed poorer absorption than TBP or TiBP. Inclusion hydrophilic PEG groups (1) – (3) also undesired...
Semi-analytical algorithms (SAAs) invert spectral remote sensing reflectance (Rrs(λ), sr−1) to Inherent Optical Properties (IOPs) of an aquatic medium (λ is the wavelength). Existing SAAs implement different methodologies with a range IOP models and inversion methods producing concentrations non-water constituents. Absorption spectrum decomposition (ADAs) are set developed partition anw(λ), m−1 (i.e., light absorption coefficient without pure water absorption), into subcomponents...
Despite the importance of optical properties such as downwelling diffuse attenuation coefficient for characterizing upper water column, until recently no in situ measurements were published Red Sea. Kirby et al. used observations from Coastal Zone Color Scanner to characterize spatial and temporal variability (K<sub>d</sub>(490)) To better understand its utility Sea, it is imperative comprehend relationship with properties. Two apparent properties, spectral remote sensing reflectance...
