Atmospheric delay modeling for satellite laser altimetry
… ranges must be corrected for certain biases. Atmospheric delay is one such bias. As the laser pulse travels through the atmosphere it will be refracted, introducing a delay into the travel time. This delay must be estimated to correct the ranges and the delay estimations need to be validated. …

Theoretical and Experimental Analysis of the Performance of Two-Color Laser Ranging Systems
In satellite laser ranging, atmospheric refraction increases the optical pathlength from the ground to an orbiting satellite. Two-color laser ranging systems can be used to determine the atmospheric delay by measuring the difference in propagation times between optical pulses transmitted at the two …

Analysis of atmospheric delays and asymmetric positioning errors in the global positioning system
Abstract Errors in modeling atmospheric delays are one of the limiting factors in the accuracy of GPS position determination. In regions with uneven topography, atmospheric delay phenomena can be especially complicated. Current delay models used in analyzing GPS data from the Plate Boundary …

Crustal deformation source monitoring using advanced InSAR time series and time dependent inverse modeling
… the signal decorrelates and is distorted by atmospheric delay. In this thesis I detail new analysis methods to reduce the limitations of conventional InSAR, by combining the benefits of advanced InSAR methods such as the permanent scatterer InSAR (PSI) and the small baseline subsets (SBAS) …
