IRSOL is a research institute in Switzerland which conducts it research on solar physics. The quality of its instrumentation is a result of decades of evolution which allows unique observations in the field of high precision solar spectropolarimetry. It has Astronomical Observatory Solar license form the centre of Locarno. It was established in 1960 by University of Goettingen, Germany which was bought by the private AIRSOL (Solar Research Institute Association Locarno) after an agreement with the German Research Foundation in 1984. It has collaborations with many research facilities around the world including Federal Institute of Technology Zurich. The research centre has advances equipment in the field of solar physics. IRSOL possesses Zurich imaging Polari meter (ZIPMOL-3) which is the unique spectropolarimeter in the world which is one of the reasons for being internationally famous.
The institute depends on the FIRSOL (Solari Foundation Research Institute Locarno). The laboratory is equipped with many modern instruments to conduct research in solar physics. IRSOL mainly carries research activities in solar physics.
The research activity in Locarno Monti carried on at the Specola Solare Ticinese and at the Istituto Ricerche Solari Locarno is made possible because of the financial support of the Associazione Specola Solare Ticinese (ASST) and of the Associazione Istituto Ricerche Solari Locarno (AIRSOL). The main goal of the scientific research carried out at IRSOL is to investigate the physical conditions of solar atmosphere, its magnetism and physical processes. It is being carried out by the scientists who have specialisation in that particular area. The research activities in IRSOL are mainly focussed on observational spectropolarimetry and instrument development, theoretical modelling of the generation and transfer of polarized radiation and numerical simulation of the solar atmosphere and numerical radiative transfer. With these research activities goes the development of numerical methods and codes in radiation magnetohydrodynamics and radiative transfer for the post-processing of the simulation data. They have several publications based on their research.
