  1. SMN Scientific Activities in Antarctica and Subantarctic regions Osvaldo M. Barturen

  2. Activities We have been in Antartica for more than 100 years. We have developed activities like the observations of meteorological variables focused in the weather forecast and observations of atmospheric chemistry parameters and physical variables like the terrestrial geomagnetism. Our agency has developed and published a number of scientific works, although the international scientific community feeds itself on our measurements and generates a large number of other projects.

  3. Argentine stations network in Antarctica REGIONAL BASIC SYNOPTIC NETWORK: ANTARCTICA 1953 1904 1979 1985 1969 1951

  4. Ozone - Antecedent • 1966 In Villa Ortúzar, observations with Dobson began, continue at the present. • 1987 In July, another equipment was installed in Marambio. • 1994 the Global Atmosphere Watch (GAW) Ushuaia Station were inaugurated, equipped with another Dobson. • 1995 another Dobson was settled in Comodoro Rivadavia Station. • 1997 AFO equipments were settled in San Julian, La Quiaca and Pilar Observatory

  5. Argentine network for Ozone • Marambio Base • Ushuaia GAW (Global) • San Julian GAW • Comodoro Rivadavia • Villa Ortuzar Observatory (record since 1966) • Pilar GAW • La Quiaca GAW

  6. GAW Program The mission of the Global Atmosphere Watch is to: • make reliable, comprehensive observations of the chemical composition and selected physical characteristics of the atmosphere on global and regional scales; • provide the scientific community with the means to predict future atmospheric states; • organize assessments in support of formulating environmental policy. GAW is considered the atmospheric chemistry component of the Global Climate Observing System (GCOS).

  7. GAW Characteristics • Stations located in "remote" places moved away of any source of contamination. In these conditions they are representative on world-wide scale. • The measures must be extended in uninterrupted form during decades to detect significant tendencies. • The used instrumentation is highly sophisticated, able to measure very small concentrations or very small variations of different components and atmospheric parameters throughout large periods of time.

  8. Programa VAG GAW Global Stations

  9. GAW Program • Around 80 countries members of the OMM participate in GAW, involving 300 stations, from which only 22 are Global. • Along with Algeria, Brazil, China, Kenya and Indonesia, Ushuaia is one of the six new installed scientific stations around the world. • Given the partial operation of Arembepe station (Brazil), Ushuaia is the only global station full operational in Central and South America.

  10. Marambio • Total Ozone Dobson • Ozone sonde • UV-b • Radionuclei • Aerosols • Solar Radiation

  11. Ushuaia GAW Station • Total Ozone Dobson • Ozone sondes (soon) • Solar Radiation • UV-b Radiation • CFCs by gas cromatography and SS flasks NOAA • Carbon Group NOAA • Surface Ozone • Carbon Monoxide

  12. Ushuaia GAW Station some results DOBSON

  14. CFC12 H1211 CFC11 Ushuaia GAW Station some results HALOCARBONS - NOAA

  15. Ushuaia GAW Station Infrastructure • Duplicated origial surface from 150 to approx 300 m2 • Better comunications, Internet • 2 new labs, conference room and facilities to inflate and ozonesonde launching.

  16. Achieves • International recognition. • Human resources of excellence in continuous improvement • Centers of Calibration of instruments totally in operation. • Own data bases and access to the world-wide Centers of collection .

  17. Plans • To maintain the profits reached and, as far as possible, to increase them. • To continue with the undertaken task, that becomes more difficult taking into account the financial asphyxia. • To extend the benefits of the system with new programs and services.

  18. Short term plans • Ozonesondes from Ushuaia (start 2007) • International Intercomparison of Dobson spectrophotometers (Nov 2006) • International Intercomparison of UV-b broadband equipment (Nov 2006) • International Intercomparison of photometers of surface Ozone (Nov 2006)

  19. Medium term plans • Establishment of a system for monitoring and characterization of VOCs, (volatile organic compounds) and reactive gases, in national scale. • Definitive expansion of the calibration Centers to the countries of region III • Definitive integration of the region with the world-wide Centers of data collection.
