Abstract Water vapor‐weighted mean temperature, T m , is a vital parameter for retrieving precipitable water vapor (PWV) from the zenith wet delay (ZWD) of Global Navigation Satellite Systems (GNSS) signal propagation. In this study, at 368 GNSS stations 2000–2012 were calculated using three methods: (1) temperature and humidity profiles ERA‐Interim, (2) Bevis – s relationship, (3) Pressure Temperature 2 model. derived first method was used as reference to assess errors other two methods....
Tomography—cross-sectional imaging based on measuring radiation transmitted through an object along different directions—enables non-invasive of hidden stationary objects, such as internal bodily organs, from their sequentially measured projections. Here we adapt tomographic methods to visualize—in one laser shot—the instantaneous structure and evolution a laser-induced propagating transparent Kerr medium. We reconstruct 'movies' pulse's diffraction, self-focusing filamentation phase...
The real-time State Space Representation (SSR) product of the GNSS (Global Navigation Satellite System) orbit and clock is one most essential corrections for precise point positioning (PPP). In this work, performance current SSR products from eight analysis centers were assessed by comparing it with final accuracy PPP. Numerical results showed that (1) accuracies GPS better than 8 cm satellite 0.3 ns clock; (2) GLONASS (GLObalnaya NAvigatsionnaya Sputnikovaya Sistema) 10 RMS (Root Mean...
We report a study of the magnetic and magnetotransport properties layered transition-metal pnictide ${\mathrm{CaMnSb}}_{2}$. ${\mathrm{CaMnSb}}_{2}$ is quasi-two-dimensional system with an orthorhombic crystal structure, containing two distinct layers distorted Sb square sheet edge-sharing ${\mathrm{MnSb}}_{4}$ tetrahedron. It was found that orders antiferromagnetically below ${T}_{\mathrm{N}}$ = 302 K exhibits expected highly anisotropic electrical transport properties. At low temperatures...
Nowadays, the Global Navigation Satellite Systems (GNSS) have become an effective atmospheric observing technique to remotely sense precipitable water vapor (PWV) mainly due their high spatiotemporal resolutions. In this study, from investigation for relationship between GNSS-derived PWV (GNSS-PWV) and heavy precipitation, it was found that several hours before probably start with a noticeable increase followed by steep drop. Based on finding, new model including five predictors...
Abstract. Surface pressure is a necessary meteorological variable for the accurate determination of integrated water vapor (IWV) using Global Navigation Satellite System (GNSS). The lack observations big issue conversion historical GNSS observations, which relatively new area applications in climatology. Hence use surface derived from either blind model (e.g., Pressure and Temperature 2 wet, GPT2w) or global atmospheric reanalysis ERA-Interim) becomes an important alternative solution. In...
We present an in-depth experimental-computational study of the parameters necessary to optimize a tunable, quasi-monoenergetic, efficient, low-background Compton backscattering (CBS) x-ray source that is based on self-aligned combination laser-plasma accelerator (LPA) and plasma mirror (PM). The main findings are (1) LPA driven in blowout regime by 30 TW, fs laser pulses produce not only high-quality, quasi-monoenergetic electron beam, but also relativistically intense (a0 ∼ 1) spent drive...
Global navigation satellite systems (GNSS) has been applied to the sounding of precipitable water vapor (PWV) due its high accuracy and spatiotemporal resolutions. PWV obtained from GNSS (GNSS-PWV) can be used investigate extreme weather phenomena, such as formation mechanism prediction rainfalls. In study, a new, improved model for rainfall forecasting was developed based on data 9-year period 2010 2018 at 66 stations located in USA. The new included three factors—PWV value, increase,...
The Chinese giant salamander Andrias davidianus is the largest living amphibian. Most wild populations are threatened and some already extinct. government has declared species a Class II Protected Species, it listed as Critically Endangered in Red Book of Amphibians Reptiles Data Deficient on IUCN List. Populations have declined sharply both range number since 1950s because habitat loss fragmentation, hunting for commercial luxury food trade. Remaining appear to be distributed 12 areas...
Abstract. The Global Positioning System (GPS) is a powerful atmospheric observing system for determining precipitable water vapour (PWV). In the detection of PWV using GPS, weighted mean temperature (Tm) crucial parameter conversion zenith tropospheric delay (ZTD) to since quality affected by accuracy Tm. this study, an improved voxel-based Tm model, named GWMT-D, was developed global reanalysis data over 4-year period from 2010 2013 provided United States National Centers Environmental...

Typhoons can be serious natural disasters for the sustainability and development of society. The a typhoon usually involves pre-existing weather disturbance, warm tropical oceans, large amount moisture. This implies that variation in atmospheric water vapor over path used to study characteristics typhoon. is reason precipitable (PWV) often capture signature meteorology. investigates usability real-time PWV retrieved from global navigation satellite systems (GNSS) typhoons’ characterizations,...
In recent years, tropospheric products obtained from ground-based global navigation satellite system (GNSS) measurements, especially the zenith total delay (ZTD) and precipitable water vapor (PWV) estimates, have advanced their usages in meteorological applications such as detection of precipitation events. Generally, a cumulative anomaly (CA) time series any atmospheric variable, which represents long-term departure variable its "normal" cycle, is widely used for quantitatively estimating...
In this study, a comprehensive investigation into the inter-relationships among twelve atmospheric variables and their responses to precipitation was conducted. These include two Global Navigation Satellite Systems (GNSS) tropospheric products, eight weather time-varying parameters. Their observations corresponding record over period 2008–2019 were obtained from pair of GNSS/weather stations in Hong Kong. Firstly, based on correlation regression analyses, cross-relationships systematically...
