Anewgravimetric geoidmodel,Canadian Gravimetric Geoid 2010 (CGG2010), has been developed to upgrade the previous geoid model CGG2005. CGG2010 represents the...
The Canadian Geodetic Vertical Datum of 2013 (CGVD2013) is the first major update to the vertical datum in Canada in almost 100 years. Canada is not only...
The objective of this study is to evaluate two approaches, which use different representations of the Earth's gravity field for downward continuation (DC), for...
Natural Resources Canada (NRCan) is presently getting ready to release a new vertical datum for the country by November 2013. The Canadian Geodetic Vertical...
For more than a century, the levelling technique has been serving well Canada in realizing and maintaining its vertical datum through a network of some 90,000...
Canada is moving to the Canadian Geodetic Vertical Datum of 2013 (CGVD2013), which will be realized by a geoid model, by November 2013. During the transition...
A Stokes approach is formulated to adjust the geoid model for a selected spherical harmonic band when spectrally combining GOCE satellite gravity models with...
A new least-squares method is developed for estimating and removing the correlated errors (stripes) from the Gravity Recovery and Climate Experiment (GRACE)...
We propose an application of joint tomographic inversion using both transmitted and reflected arrivals to map velocity structures in thick permafrost areas of...
We present a joint transmission and reflection traveltime tomography algorithm based on the Fast Sweeping Method and the adjoint-state technique. In contrast...
