Resumen:
In the present work we analyze sites in the Argentinian high Andes mountains as possible places for astrophysical/astronomical/solarobservatories. They are located at: San Antonio de los Cobres (SAC) and El Leoncito/CASLEO region: sites 1 and 2. We consider thefollowing atmospheric components that affect, in different and specific wavelength ranges, the detection of photons of astronomical/astrophysical/solar origin: ozone, microscopic particles, precipitable water and clouds. We also determined the atmospheric radiative trans-mittance in a day near the summer solstice at noon, in order to confirm the clearness of the sky in the proposed sites at SAC and ElLeoncito. Consequently, all the collected and analyzed data in the present work, indicate that the proposed sites are very promisingto host astrophysical/astronomical/solar observatories. Some atmospheric components, like aerosols, play a significant role in the atten-uation of light (Cherencov and/or fluorescence) detected in cosmic rays (particles or gamma photons) astrophysical observatories, whileothers, like ozone have to be considered in astronomical/solar light detection.
