Dear Colleagues,

for those who attend the EGU2015, please join at the Splinter meeting:

IAG Joint Working Group on Gravity Modeling and Inversion (public)
Convener: Carla Braitenberg
Tue, 14 Apr, 12:15–13:15 / Room Y3

Best regards,
Carla

We added a new software isGrafLab (Irregular Surface GRAvity Field LABoratory), which is a modified version of GrafLab. isGrafLab is capable to perform fast (it uses accelerated routines) and yet sufficiently accurate spherical harmonic synthesis on dense grids at irregular surfaces (e.g. the Earth surface). Any comments, criticism or queries will be appreciated. Feel free to write us. The emails can be found e.g. in the article or in the source code.

The paper "Reguzzoni, M., D. Sampietro and F. Sansò (2013), Global Moho from the combination of the CRUST2.0 model and GOCE data, Geophysical Journal International 2013; doi: 10.1093/gji/ggt247" has been added in the page "GOCE and other satellites", section "GOCE and Solid Earth Geophysics". 

A link to the paper can be found here.

We added a new software (Spherical Harmonic Manipulator) to make fast synthesis of spherical harmonics global models.
The software allows the synthesis of many functionals on grids or point-wise provided in geodetic or spherical (geocentric) coordinates up to an arbitrary degree.

The SW is able to provide the following outputs:
T – Anomalous potential
N – Geoid undulation
Dg – Gravity anomaly
First derivatives (lambda, theta, radial)
First derivatives (east, north, radial)
Second Derivatives (All the combinations)
Third radial derivate of T

Any comments are welcomed.

We added a new MATLAB-based software (GrafLab) equipped with a GUI for spherical harmonic synthesis (under Software/Public). GrafLab allows fast synthesis of many functionals on grids or point-wise up to an arbitrary degree essentially. Any comments or questions are welcomed. The emails can be found e.g. in the article or in the source code.

Thank’s Valeria to the preliminary list on gravity inversion in flatland- I knwo you are still working at it. We shall decide on the formatting of the references and whether the links to the papers shall be included- Adding the links is quite some work, so I am not sure if everybody is willing to do it.
Suggestions welcome!
