New velocity model VEMOS2015

A new SIRGAS Velocity Model (VEMOS2015) was inferred from GNSS (GPS+GLONASS) measurements gained after the strong earthquakes occurred in 2010 in Chile and Mexico. It is based exclusively on the multi-year solution SIR15P01, which comprises 456 continuously operating GNSS stations covering a five years period from March 14, 2010 to April 11, 2015. VEMOS2015 covers the region from 55°S, 110°W to 32°N, 35°W with a spatial resolution of 1° x 1°. The average prediction uncertainty is ±0.6 mm/a in the north-south direction and ±1.2 mm/a in the east-west direction. The maximum is ±9 mm/a in the Maule deformation zone (Chile) while the minimum values of about ±0.1 mm/a occur in the stable eastern part of the South American plate. VEMOS2015 is available at https://doi.pangaea.de/10.1594/PANGAEA.863132.

When using VEMOS2015, please always quote the following citation:

New multi-year solution SIR15P01

The IGS RNAAC SIR (IGS Regional Network Associate Analysis Centre for SIRGAS) under the responsibility of DGFI-TUM (Deutsches Geodätisches Forschungsinstitut, Technische Universität München) released recently a new multi-year solution for the SIRGAS reference frame. This solution, called SIR15P01, was computed using GNSS (GPS+GLONASS) observations gained after the strong earthquakes occurred in 2010 in Chile and Mexico. It covers a five years period from 2010-03-14 to 2015-04-11. SIR15P01 includes positions and velocities of 303 SIRGAS reference stations and 153 additional stations, which are considered to improve the station distribution towards a post-seismic surface velocity model. SIR15P01 refers to the IGb08 frame, epoch 2013.0. The averaged RMS precision for the station positions at the reference epoch is ±0.7 mm in the north-south component, ±0.9 mm in the east-west component, and ±3.5 mm in the height. The averaged RMS precision for the station velocities is ±0.5 mm/a in the north-south component, ±0.8 mm/a in the east-west component, and ±1.6 mm/a in the vertical component. Results are available at https://doi.pangaea.de/10.1594/PANGAEA.863132.

This was a capacity building activity supported by the project "Monitoring crustal deformation and the ionosphere by GPS in the Caribbean" sponsored by the International Union of Geodesy and Geophysics (IUGG) through the International Association of Seismology and Physics of the Earth's Interior (IASPEI), the International Association of Geodesy (IAG), and the International Association of Geomagnetism and Aeronomy (IAGA). This School was also supported by the Pan-American Institute for Geography and History (PAIGH). Thanks to the contact established in that opportunity, representatives of the Dominican Republic participated in the SIRGAS Symposia 2013 and 2014. As a result of this approach, we welcome the Dominican Republic as a new SIRGAS member and announce that the Symposium SIRGAS 2015 will take place in Santo Domingo under the coordination of the Universidad Nacional Pedro Henríquez Ureña (UNPHU).

Actualization of the IGS08 Reference Frame

The IGS released a new version of the IGS08 Reference Frame called IGb08. Since many of the IGS08 stations have been affected by discontinuities since 2009.5, they are now unusable for operational reference frame alignments. In particular, the IGS08 core network has dropped to about 50 usable stations recently, leaving large holes in South America, Africa, and Eastern Asia. This situation led IGS to propose an update of IGS08, called IGb08. It mainly includes new sets of coordinates for 33 IGS08 stations having been affected by position discontinuities since 2009.5, and 3 new stations co-located with decommissioned IGS08 stations. The IGb08 Reference Frame replaces the IGS08 Reference Frame since October 7, 2012, GPS week 1709. More details in [IGSMAIL 6663].

Improvement of the IGS station coverage in Latin America

After the strong earthquake of February 2010 in the Chilean Region Maule, a huge percentage of existing IGS reference frame stations in South America suffered an irreparable discontinuity in their time series. Thereby, the reliability of the recently launched ITRF2008 and IGS08 reference frames decreased considerably in South America and the affected stations are no longer usable as a basis for the GNSS data analysis or to guarantee the long-term stability of the ITRF in this region. Keeping in mind the achievements reached within the regional reference frame SIRGAS and the planned second reprocessing campaign of the IGS global network, a set of continuously operating SIRGAS stations was proposed to be included in this reprocessing with the main objective of improving the IGS station coverage in Latin America. Initially, the IGS Regional Associate Analysis Centre for SIRGAS (IGS RNAAC SIR), with the support of the national organizations responsible for the reference frames in the Latin American countries, made a selection of about 70 SIRGAS stations satisfying the IGS requirements. This selection was evaluated by the IGS Reference Frame Working Group, and after some interaction with the IGS Global Analysis Centres, it was decided to include 40 SIRGAS stations not only in the IGS reprocessing but also in the present routine IGS processing. SIRGAS provided the IGS data centres with the metadata and all existing observations (historical data) of the selected stations by the end of January 2012. Present measurements (since the beginning of 2012) of the operational stations are directly provided by the responsible Latin American agencies to the IGS. The next step is to manage, together with the IGS Network Coordinator, the formal integration of these stations in the IGS network [... more].

August, 2007

The SIRGAS web page is moved from IGM-Argentina to www.sirgas.org. It keeps the same design introduced by IGM-Argentina and IBGE in the previous web sites. A new section about the SIRGAS Continuously Observing Network (SIRGAS-CON) is implemented. The SIRGAS Vicepresident, Laura Sánchez from Deutsches Geodätisches Forschungsinstitut (DGFI), is responsible for maintaining the new SIRGAS web site.

December, 2004

The SIRGAS Vicepresident, Eduardo Lauría, assumed the maintenance and modernization of the SIRGAS web site and it is moved from IBGE to the Instituto Geográfico Militar of Argentina. This new site offered interactive tools to easily find the SIRGAS95 and SIRGAS2000 coordinates for desired stations as well as to get station velocities from the VEMOS model. New sections corresponding to the SIRGAS Working Groups were introduced. The timely presentation of the SIRGAS Reports through the web site was continued.

November, 2002

The first version of the SIRGAS web page is designed, implemented, and kept by the Instituto Brasileiro de Geografia e Estatística, IBGE, affiliation of the current SIRGAS President, Luiz Paulo Souto Fortes. This web site described the objectives and structure of SIRGAS, included the new SIRGAS Bylaws, and contained the main SIRGAS products: SIRGAS95 and SIRGAS2000 coordinates and the VEMOS model. Through this web site the routinely issue of the SIRGAS Newsletters was established.

October, 2002

With the adoption of the SIRGAS Bylaws in October 2002, SIRGAS President and Vicepresident begin the design and maintainance of the SIRGAS web site.
