The 9th International Symposium on Tropospheric Profiling (ISTP) will be held in L'Aquila, Italy from September 3th-7th, 2012. It is hosted by the Center of Excellence for the Forecast of Severe Events (CETEMPS) of University of L'Aquila. The symposium is part of a series that started in Boulder, Colorado, in 1988, and it is typically held every 3 years.

The ISTP Symposium is a great venue for vendors  providing opportunities to interact with leading scientists in atmospheric instrumentation and research.

ISTP attracts an international group of scientists, engineers, and program managers with broad experience in atmospheric measurement and modeling. Profiling of atmospheric state parameters and constituents, the understanding of tropospheric processes, and the use of experimental data in atmospheric models are the major topics of the conference.

ISTP will include invited topical lectures, contributed talks, and panel discussions. The ISTP program aims to include the following plenary Sessions:

- Aerosols, clouds and precipitation
- Algorithms for improved parameter retrievals
- Atmospheric radiation
- Boundary layer and mesoscale studies
- Evaluation of models and data assimilation
- Networks, satellites, and aircrafts
- New instruments
- Temperature, wind, waves, and turbulence
- Validation, instrument synergies, and field experiments
- Water vapor, ozone and trace gases
