The region surrounding the Llano de Chajnantor, a high‐altitude plateau in the Atacama Desert in northern Chile, has caught the attention of the astronomical community for its potential as an observatory site. Combining high elevation and extremely low atmospheric water content, the Llano has been chosen as the future site of the Atacama Large Millimeter Array. We have initiated a campaign to investigate the astronomical potential of the region in the optical/infrared. Here we report on an… 

The Optical/Infrared Astronomical Quality of High Atacama Sites. II. Infrared Characteristics

We discuss properties of the atmospheric water vapor above the high Andean plateau region known as the Llano de Chajnantor, in the Atacama Desert of northern Chile. A combination of radiometric and

Seeing environment at a 5640m altitude of Co. Chajnantor in northern Chile

We have carried out a campaign to monitor seeing at a 5640m altitude on the summit of Co. Chajnantor at Atacama, for the 6.5m telescope TAO project planned by the University of Tokyo. The seeing

ANIR : Atacama Near-Infrared Camera for the 1.0-m miniTAO Telescope

We have developed a near-infrared camera called ANIR (Atacama Near-InfraRed camera) for the University of Tokyo Atacama Observatory 1.0m telescope (miniTAO) installed at the summit of Cerro

Worldwide site comparison for submillimetre astronomy

Aims. The most important limitation for ground-based submillimetre (submm) astronomy is the broad-band absorption of the total water vapour in the atmosphere above an observation site, often

Simulation of submillimetre atmospheric spectra for characterising potential ground-based remote sensing observations

Abstract. The submillimetre is an understudied region of the Earth's atmospheric electromagnetic spectrum. Prior technological gaps and relatively high opacity due to the prevalence of rotational

Infrared Optimized AO System for a 15 - 20m Class Telescope

Despite the relatively large number of proposed 'extremely large telescopes' very few of them concentrate on the thermal infrared as their main operating wavelengths. An IR-optimized large telescope

Optical Seeing at Sierra Negra

Optical seeing measurements carried out at Sierra Negra, the site of the Large Millimeter Telescope, are reported. The site, one of the highest peaks in central Mexico, offers good coverage of the

Tibet's Ali: Asia's Atacama?

The Ngari (Ali) prefecture of Tibet, one of the highest areas in the world, has recently emerged as a promising site for future astronomical observation. Here, we use 31 yr of reanalysis data from

Some design considerations for an extremely large synthesis array

An Extremely Large Synthesis Array (ELSA) with 27 ten-meter telescopes and baseline lengths up to 10 km would provide completely new insight into many astrophysics phenomena. It could be used to

Measurement of optical seeing on the high antarctic plateau

Results from the 1995 season of site-testing experiments at the South Pole are presented, in which the seeing was measured using balloon-borne microthermal probes. Our analysis shows a marked
