The Centre for Observation and Modelling of Earthquakes, Volcanoes and Tectonics (COMET) is a NERC Centre of Excellence that uses satellite measurements alongside ground-based observations and geophysical models to study earthquakes and volcanoes, and help understand the hazards they pose.
Since April 2014, we have been working in partnership with the British Geological Survey (BGS) to deliver cutting-edge research on earthquakes and volcanoes as well as hazard monitoring services. We also work closely with the Natural Environment Research Council (NERC), National Centre for Earth Observation (NCEO) and European Space Agency (ESA), as well as many other national and international partners.
Permafrost dynamics in the remote Canadian Arctic revealed by high resolution topographic measurements
On 19th July Katy Willis (PhD student funded through a LiCS grant) was a STEM Ambassador at an Earth Observation themed day for year 8 and 9 students. Read about her experience.
The Generic Atmospheric Correction Online Service for InSAR (GACOS), developed by Zhenhong Li’s team at Newcastle University can now be found online at http://ceg-research.ncl.ac.uk/v2/gacos/.
GACOS utilises High Resolution ECMWF (spatial resolution: 16 km, temporal resolution: 6h) and GNSS data to generate high resolution tropospheric delay maps for InSAR atmospheric correction.
Notable features include global coverage; all weather, all the time; correction maps available in near real time; and performance indicators available.
The GNSS module will be available in the near future with two options: (i) GNSS derived tropospheric delay products to be uploaded by users; (ii) GNSS derived tropospheric delay products to be automatically extracted from IGS or Nevada Geodetic Lab.
Since SRTM DEM (90m) is used, the polar regions are not covered yet (ASTER GDEM will be used in the polar regions).
