Routine production of meteograms with WRF at 1km grid size

In order to correct the Sentinel-1 interferograms produced routinely, we have set-up a routine production of « meteograms » made using the WRF code at 1km grid size in the CRL area.

A WRF model is produced for all epochs (every 30mn) and we extract those acquired at the time of the ascending and descending sentinel passes (4:30am and 4:30pm).

The difference of two WRF grids is what we call a meteogram.

 

Earthquake catalogs and seismicity maps

  • Earthquake catalogs are based on automatic detection and picking. Magnitudes Mw and Ml are also computed automaticaly. Locations are calculated in the 1D velocity model of Rigo et al. (1996) using hypo71 location code. Mw and Ml are calculated using SourceSpec (Satriano, 2020)

Rigo, A., H. Lyon-Caen, R. Armijo, A. Deschamps, D. Hatzfeld, K. Makropoulos, P. Papadimitriou, and I. Kassaras (1996), A microseismic study in the western part of the Gulf of Corinth (Greece) : Implications for large-scale normal faulting mechanisms, Geophys. J. Int., v. 126(3), pp. 663-688.

Satriano, C. (2020) SourceSpec-Earthquake source parameters from S-wave displacement spectra. DOI: 10.5281/ZENODO.3688587

  • Format of catalogs is as follows: year, month, day, hour, minute, seconds, latitute, longitude, depth, Mw, Ml, erx, ery, erz, rms, number of P phases, number of S phases, quality (according to hypo71)
  •  Seismicity maps: quality A events (best ones) are in dark red, quality B in red, quality C in orange and quality D (low reliability) in yellow... Size is proportional to seismic moment.

NOA WRF modelling of the troposphere

The central area (AREA-4), with ~1km pixel size and 30mn temporal scale, is surrounded by tha Areas 3, 2 and 1, all with 3h temporal scale

MOSAIC ITN-EJD Project Summary

This ITN-EJD gathers universities and institutions from five countries, France, Greece, Czech Republic, Italy, Bulgaria, collaborating in the Corinth Rift Laboratory (http://crlab.eu), one of the EPOS Near Fault Observatories. The training network covers the various aspects of Geodesy already used for the research at CRL (GNSS, SAR interferometry, gravity) and those that we want to develop (sea level measurements, tilt measurements, off-shore Geodesy). Many of the techniques in use are evolving quickly from the technological point of view: GNSS with the arrival of new constellations like GALILEO and new positioning techniques like the PPP, SAR interferometry with several recent missions like SENTINEL, gravity with the development of new absolute gravity sensors based on cold atoms technologies, off-shore sensors for distance, strain, depth, tilt, gravity observations developed with a strong push of the industrials and also because of the need of more geophysical observations off-shore (e.g. for resources prospecting, meteorology, tsunami detection). The area of investigation for the ITN team is the « extended CRL area », which covers the NFO itself and the Ionian islands to the west. At such scale the partnership is beneficial not only for the NFO itself but also for the understanding and better assimilation of the boundaries conditions of the NFO, from the geophysical points of view (e.g. how the rifting process is related to the underlying subduction), and from the methodological point of view (e.g. in GNSS meteorology or in sea level analysis). The space observation plays an important role in this ITN, bridging the various work packages. The ESR involved in the ITN will have the opportunity to work in collaboration with several of the partner institutions, they will have the opportunity to do fieldwork in-land and/or off-shore. The ESR will also contribute to outreach activities in the targeted area
