University of Arizona Webcam in Tucson — Live HD Stream

Live Stream from the Computer Science Department

This online camera broadcasts from the upper floors of the Gould-Simpson building — one of the most prominent buildings at the University of Arizona in Tucson. The panoramic view encompasses not only the campus grounds with their characteristic red-brown brick architecture, but also the majestic Santa Catalina Mountains on the horizon. The webcam operates in real time and allows you to observe the life of one of the leading research universities in the southwestern United States.

Gould-Simpson Building: History and Architecture

The Gould-Simpson building was constructed in 1985 and is one of the tallest on campus — it has 10 floors. The name honors two distinguished geology professors: Lawrence M. Gould and George G. Simpson, whose research made significant contributions to the development of natural sciences at the university.

Today the building houses the Department of Computer Science and the Department of Physics. It is here, on the top floor, that the webcam is installed, providing a continuous broadcast. Students and researchers of the Computer Science Department work in one of the most technologically equipped buildings on campus, and the CSGrid project with 64 computing nodes provides remote computing for scientific tasks.

Santa Catalina Mountains: Tucson's Natural Landmark

In the background of the broadcast, the Santa Catalina Mountains are visible, located north and northeast of Tucson. Their area is about 923 km². The highest point of the range is Mount Lemmon at 9,157 feet (2,791 m).

Mount Lemmon is named after botanist Sarah Lemmon, who in 1881, together with her husband John, made an expedition to the summit and discovered many new plant species. The Santa Catalina Mountains are part of the Coronado National Forest and belong to the unique "sky islands" ecosystems — high-elevation massifs with coniferous forests that contrast with the surrounding desert.

University of Arizona Campus: History and Scale

The University of Arizona was founded in 1885 by the 13th Territorial Legislature of Arizona as the first university in the territory of the future state. The campus occupies 325 acres (about 131 hectares) in downtown Tucson and has been developing for over 135 years.

The oldest building on campus — Old Main opened in 1891, more than 20 years before Arizona became a state (1912). Originally it housed classrooms, a library, offices, and dormitories. The campus historic district includes 18 architectural landmark buildings from the early 20th century in the Neoclassical style. Old Main and the university library were listed in the National Register of Historic Places even before the historic district itself was established.

Tucson Climate: Monsoons and Dust Storms

Tucson has a hot desert climate with long hot summers and mild winters. Spring and fall here are sunny and dry. However, the summer season brings unique weather phenomena that can be observed through the webcam.

The monsoon season in Tucson officially begins on June 15, but the first monsoon storms arrive on average around July 3. Thunderstorms are responsible for most dust storms in the central deserts of Arizona. A monsoon thunderstorm can create a dust wall (haboob) accompanied by strong winds, lightning, and downpours. Dust storms have existed in Tucson for centuries — the dry climate and abundance of arid soils create conditions for wind-blown dust.

Computer Science Department: Research and Rankings

The University of Arizona Department of Computer Science focuses on high-quality research and education. According to the National Research Council ranking, it is in the top 33 of 108 doctoral programs in the US. The University of Arizona is in the top 100 of 168 research topics according to EduRank.

The CS Department is known for the CSGrid project — a computing infrastructure with 64 nodes for remote computing. Real-time webcams are also part of the department's technological infrastructure, demonstrating a commitment to innovation and openness.

What's Visible on the Camera

The online camera from the University of Arizona Computer Science Department broadcasts a panoramic view from the upper floors of the Gould-Simpson building. In the foreground are university buildings with characteristic red-brown brick architecture and tile roofs, green plantings, parking areas, and campus roads. In the background rises the Santa Catalina mountain range, behind which the urbanized area and city development of Mesa are visible. Depending on the time of day and weather conditions, the picture changes: during the day, campus details and mountain slopes are clearly visible, during the monsoon season you can observe thunderstorm clouds and dust storms, and at night — the lights of Tucson at the foot of the mountains.
