tropospheric error modeling for gps positioning
in this paper a practical method for tropospheric effects on gps derived coordinates in absolute mode is presented. gps observations at the permanent gps stations can be used as source of information for the modeling. the developed model is a time-dependent model and as such differs from usual tropospheric models, which are based on atmospheric parameters, i.e. temperature, pressure and humidit...
متن کاملDetermining Tropospheric Concentrations of Trace Gases from Space
Background The new observations of the tropospheric distributions of trace gases such as NO2 (nitrogen dioxide), SO2 (sulphur dioxide), HCHO (formaldehyde), BrO (bromine monoxide) and O3 (ozone), retrieved from GOME (Global Ozone Monitoring Experiment) measurements, herald the opening of a new era for tropospheric production, as a result of agricultural activities, and above all by vehicles suc...

متن کاملTropospheric Range Error at the Zenith
The atmospheric range error in an electromagnetic signal arriving vertically at the earth is measured by the height integral of the refractivity N through the atmosphere. (N = 10^ (n-1) where n is the index of refraction.) N in the non-ionized atmosphere is the sum of "dry" and "wet" components, which are considered separately. Only the dry part is important at optical wavelengths,and the prese...
متن کاملA global single-sensor analysis of 2002–2011 tropospheric nitrogen dioxide trends observed from space
[1] A global nine-year archive of monthly tropospheric NO2 data acquired by the SCanning Imaging Absorption spectroMeter for Atmospheric CartograpHY (SCIAMACHY) instrument was analyzed with respect to trends between August 2002 and August 2011. In the past, similar studies relied on combining data from multiple sensors; however, the length of the SCIAMACHY data set now for the first time allows...
