The 2nd TIGER Symposium, 9-10 June, 1999

S.I. Vavilov State Optical Institute, St. Petersburg, Russia

TIGER (Thermospheric/Ionospheric GEospheric Research) is the Program of SCOSTEP/ISCS/WG 1.2 concerned with long-term measurement of solar EUV/UV fluxes for thermospheric/ ionospheric modelling and for space weather investigations.

The Chair of the Program Committee was Gerhard Schmidtke, Fraunhofer-Institute Physical Measurement Techniques, Freiburg, Germany. The Chair of the Local Organizing Committee was

Dr. of Sc. Sergei V. Avakyan, S.I. Vavilov State Optical Institute.

Seven topics were considered during the Symposium:

  1. Measurement and modelling of solar EUV/UV radiation; K. Tobiska, Jet Propulsion Laboratory, USA
  2. Modelling of the solar wind originated energy T/I influx; J.D. Winningham, Southwest Research Institute, USA
  3. Measurement of relevant thermospheric-ionospheric parameters from space: R. Link, Southwest Research Institute, USA
  4. Modelling of the thermosphere/ionosphere: S. Solomon, Laboratory for Atmospheric and Space Physics, USA
  5. Basic physical investigations to support the preceding topics: I. Kanik, Jet Propulsion Laboratory, USA
  6. Rocket investigations: Gerhard Schmidtke, Fraunhofer-Institute Physical Measurement Techniques, Germany
  7. Measurements from ground: Ch. Lathuillere, Laboratoire de Planetologie, France

The Proceedings of the TIGER Symposium will be published in a special edition of the Journal 'Physics and Chemistry of the Earth, Part C: Solar-Terrestrial and Planetary Science'.

Resolutions of the TIGER Symposium

Resolution 1

The second TIGER Symposium, having met and considered a presentation on the ISO "Process for determining solar irradiances" draft standard,

agree with the importance of developing such a standard and

resolve to provide scientific and data support expertise in developing the standard for solar full-disk spectral irradiances

Resolution 2

Noting that there is tremendously growing demand to investigate and to measure the solar XUV (X-ray to extreme ultraviolet) radiation at high radiometric accuracy for scientific studies of the upper atmosphere as well as for applications in fields such as communication and navigation,

Acknowledging that there is a great potential of experience, valuable equipment, and space mission capability to conduct sophisticated tasks by the famous Vavilov State Optical Institute in St. Petersburg, Astrophysics Institute of Moscow State Engineering Physics Institute, IZMIRAN, Fedorov Institute of Applied Geophysics in Moscow, A.F. Ioffe Physico-Technical Institute in St. Petersburg

the community of the ISCS/SCOSTEP TIGER program (Thermospheric/Ionospheric Geospheric Research)

strongly recommends support of projects to investigate the Solar XUV radiation and its interaction with our environment. This includes the development and calibration of radiometric equipment as well as its application and use in space missions.
