GPS tomography: validation of reconstructed 3-D humidity fields with radiosonde profiles [PDF]
Annales Geophysicae, 2013 Water vapor plays an important role in meteorological applications; GeoForschungsZentrum (GFZ) therefore developed a tomographic system to derive 3-D distributions of the tropospheric water vapor above Germany using GPS data from about 300 ground ...

INVESTIGATION OF THE AIR QUALITY CHANGE EFFECT ON GNSS SIGNALS [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017 Air pollution is the most important environmental problem in Zonguldak city center. Since bituminous coal is used for domestic heating in houses and generating electricity in thermal power plants, particulate matter (PM10) is the leading air pollutant ...

Kinematic GNSS Estimation of Zenith Wet Delay over a Range of Altitudes
Journal of Atmospheric and Oceanic Technology, 2016 AbstractAtmospheric water vapor estimates from static ground-based Global Navigation Satellite System (GNSS) receivers are now operationally assimilated into numerical weather prediction models, either as total precipitable water vapor (PWV) or zenith total delay.

Tropospheric Refractivity Profile Estimation by GNSS Measurement at China Big-Triangle Points
Atmosphere, 2021 Atmospheric radio refractivity has an obvious influence on the signal transmission path and communication group delay effect. The uncertainty of water vapor distribution is the main reason for the large error of tropospheric refractive index modeling ...

Intercropping mitigates incidence of the oilseed rape insect pest complex
Pest Management Science, EarlyView.Intercropping reduces the incidence of the oilseed rape insect pest complex with a significant impact of the direct visual and physical disruption provided by the companion plant. Abstract BACKGROUND Oilseed rape (OSR, Brassica napus) is a major crop requiring numerous phytosanitary treatments.

Developing a global model for the conversion of zenith wet tropospheric delays to integrated water vapour [PDF]
Acta Geodaetica et Geophysica, 2018 The tropospheric wet delay is a significant systematic error of GNSS positioning, nevertheless it carries important information to meteorologists. It is closely related to the integrated water vapour that is the upper limit of precipitable water. The zenith wet delay can be converted to the integrated water vapour using a simple conversion factor. This
