We plan to extract weather relations between the Chajnantor Plateau and Hoch oben auf dem Chajnantor-Plateau in den chilenischen Anden betreibt die Europäische Südsternwarte (ESO) zusammen mit ihren internationalen Partnern das Atacama Large Millimeter/Submillimeter Array (ALMA) - ein hochmodernes Teleskop zur Untersuchung des Lichts einiger der kältesten Objekte des Universums. 1 The Chajnantor Plateau The ALMA observatory [Wootten and Thompson, 2009] is located on the Chajnantor Plateau at an altitude of 5 km (Figure 1) and is one of the driest sites on Earth's surface, outside of Antarctica, with median precipitable water vapor of 1. We plan to extract weather relations between the Chajnantor Plateau and This is the view of the Chajnantor Plateau that greeted NRAO astronomers who were exploring the northeastern region of Chile as a potential site for a millimeter/submillimeter wave telescope array then known as the MMA. However, due to its position on the plateau of Chajnantor, the top of Cerro Chico offers an excellent and relatively easy-to-reach vantage point from which to enjoy this stunning view. . Time-lapse video of the Chajnantor plateau, in Chile’s Atacama region. De antennes kunnen worden verplaatst over het Chajnantor-plateau. Although this value is close to previous results [i. Abstract In situ measurements of water vapor isotopic composition from the subtropical Chilean Andes, supported by mesoscale model simulations and diagnostic analyses, document the processes governing the transport of dry air and isotopically depleted water vapor from the midlatitudes into the subtropics during a South American cold-air surge in July 2014. Knowing the general site annual variability in precipitable water vapor (PWV) can contribute to the planning of new observatories in the area. 2002) site, the data comes from the weather station installed to support the operations of the telescope. Thunderstorms, lightning and light- ning electromagnetic pulses occur during the entire year, but especially during winter time. It's one of the highest roads of the country. , J.

This location was chosen for its high elevation and low humidity , factors which are crucial to reduce noise and decrease signal attenuation due to Earth's atmosphere. 1) The weather condition at the summit is slightly harsher than the condition at the Pampa la Bola plateau. Therefore this <italic>Context. 01. m. Maximum speed of the wind is 35m/s, and minimum temperature is about -10 degree. Im Umfeld eines Observatoriums auf dem Chajnantor-Plateau maßen Forscher um Raùl Cordero zwischen 2016 und 2021 einen Rekordwert der Sonneneinstrahlung, der sie tatsächlich an einen anderen Planeten erinnerte: Wie sie ALMA AOS, 5,050 m: Location of the antenna array and a technical building that houses the ALMA supercomputer: the Correlator. This video, nearly 15 minutes long and produced in 2004, showcases the efforts made to realize the creation of the Atacama Large Millimeter/submillimeter Array (ALMA) in northern Chile. The main ridge of the Andes is over 200 kilometres (120 mi) to the east, well into Argentina. 050m de altitud. For example, in [Delgado et al. The plateau features a large fraction of days during the year where dry and stable atmospheric conditions predo There are a number of publications in the literature referring to PWV and weather conditions in the Chajnantor area and their implications to astronomy. from publication: Precipitable Water Vapor, Temperature, and Wind Statistics This video documents the production of the reflector for one of the Japanese 12-meter antennas and a sub-reflector for a 7-meter antenna. The paired measurements are highly correlated ( ) and indicate the 350 μ m atmospheric transparency is significantly better on Cerro Chajnantor than on the plateau. 5 million science files Select Language (es) 21 likes, 4 comments - discoveraui on December 19, 2024: "While the Chajnantor Plateau of the Chilean Andes – home of @alma. 00°S, 67. This 360 degree panorama picture is centred on the northeast, where the highest volcanoes — most of them above 5500 metres — are seen.
