Advanced data processing with
GAMIT/GLOBK/TRACK
Apr 4-5, 2012, Thessaloniki,
Greece
|
This
two day advanced workshop is aimed at users already familiar with the basic
operations of GAMIT, GLOBK and TRACK and with working in the UNIX
environment. The workshop will
held over two days with the first day dealing with GAMIT/GLOBK, and the second
day dealing with TRACK. Each day
will be divided into lectures in the morning and tutorial sessions in the
afternoons. In the GAMIT/GLOBK session, under GAMIT we will look at advanced
data modeling methods in GAMIT and identifying problems such as incorrect
antenna types. The bulk of the
class will be spent on GLOBK analysis methods including reference frame
realization, use of MIT global H-files, treatment of earthquakes including
post-seismic deformation, analysis of large data sets with particular attention
on numerical stability issues and stacking of data, the use of SINEX for
importing and exporting results, and noise processes appropriate for tectonic
studies. The tutorial session in the afternoon will analyze data collected
during a moderate size earthquake and how these data are combined in GLOBK. |

The
second day will deal with TRACK again with lectures in the morning and
tutorial in the afternoon. The TRACK lectures will cover kinematic processing
issues focused on long baseline results incorporating the impact of the
ionospheric delays, methods for resolving the integer phase ambiguities and
the impact of non-resolved ambiguities and incorrectly resolved ambiguities.
The output diagnostics from TRACK will also be discussed. If there is interest
from the class, the real-time version of TRACK, trackRT, will also be
discussed. Extensive
experience with track processing is not required for the second day. In the tutorial session we will focus
on long baseline analysis of high rate surface wave data from an earthquake
in Southern California. |

|
During
the tutorial sessions, students may work on their own data sets and issues
associated with these data sets can be discussed. Prior to the workshop,
topics of particular interest can be suggested and if possible they will be
accommodated in the workshop.
Students are expected to bring a laptop with the software installed
and have already run basic data analyses with the software. |
