For more than 50 years, the University of Wisconsin-Madison has been a leader in devising ways to view our planet through the eye of a satellite. In particular, scientists at the UW-Madison Space Science and Engineering Center (SSEC) have been at the forefront of developing the satellite technology that makes it possible to see and study the intricacies of Earth’s atmosphere from space. Some of the earliest experiments, beginning in the 1950s, were led by Professor Verner E. Suomi, founder of the Space Science and Engineering Center, and Professor Robert J. Parent, of the UW-Madison College of Engineering. Continuous observations of the Earth’s atmosphere from space revolutionized scientists' understanding of the motions of the atmosphere, paving the way for more accurate weather forecasts and faster and more precise warnings for severe weather, which have saved many lives and mitigated damage from storms and other severe weather events. Suomi’s contributions set the foundation for the technologies that made the routine observing of the Earth's weather from space possible. For those contributions, he is widely considered to be the “father of satellite meteorology.” With the establishment at Wisconsin of the Cooperative Institute for Meteorological Satellite Studies (CIMSS) in 1980, satellite meteorology research at UW-Madison was bolstered through a more formal working relationship with the National Oceanic and Atmospheric Administration (NOAA). NOAA stations scientists at CIMSS to work side-by-side with Wisconsin researchers to continue the pioneering research begun by its founder, Verner E. Suomi.

View on timelineVerner Suomi and Robert Parent's instrument for measuring the heat balance of the earth was included in the payload of Vanguard SLV-6 launched on 22 June. A faulty second stage pressure valve caused mission failure.
View on timelineInstrumentation developed by Verner Suomi and Robert Parent, University of Wisconsin-Madison, to measure the earth's heat balance was included in the payload of Explorer 7X (also known as Explorer S-1), launched on July 16. The rocket was intentionally destroyed by the Range Safety Officer five and a half seconds after liftoff because of a failure of the power supply to the guidance system. The rocket crashed and burned approximately 150 feet from the blockhouse where Suomi, Parent and others were trapped for about an hour. After it had cooled they hacksawed their instrument package from the wreckage.

View on timelineATS-I, the first geostationary satellite, launched on December 7, 1966 (UTC). It carried Robert Parent and Verner Suomi's Spin-Scan Cloud Camera (SSCC), the technology that made viewing Earth from geosynchronous orbit possible. The launch of ATS-I ushered in the era of continuous viewing of weather from space. Suomi understood the benefits of observing a single weather phenomenon over time. These kinds of observations were not possible using the early, low-altitude polar-orbiting satellites. Identical experiments were flown on the ESSA 5, ESSA 7, and ESSA 9 spacecrafts. The radiometer performed normally, and good data was obtained from launch until the tape recorder failed on January 20, 1967.

Verner Suomi, University of Wisconsin-Madison, was the principal investigator on the FPR, which was one of two experiments in the payload of the satellite. The experiment performed normally, and good data was obtained from launch until September 22, 1967, when the radiometer failed. Identical experiments were flown on ESSA 3, 7, and 9 spacecrafts.
View on timelineATS-III launched on November, 5 1967. It sent the first color images from the Multicolor Spin-Scan Cloudcover Camera (MSSCC), the second generation of UW-Madison professor Verner Suomi's revolutionary technology. The ATS-III was the only geostationary satellite with a channel for observing phenomena in true blue color, which was, and remains, a unique feature for a weather satellite. The camera provided color pictures for approximately three months at which time the red and blue channels failed. The system continued to transmit black-and-white pictures until December, 11 1974.

The experiment was turned off on May 21, 1970. Identical experiments were flown on the ESSA 3, 5, and 7 spacecrafts.
View on timelineVerner Suomi, University of Wisconsin-Madison, is credited with the concept of the VAS instrument. The VAS (a second-order acronym for VISSR (Visible and Infrared Spin-Scan Radiometer) Atmospheric Sounder) evolved from a concept for sounding from geosynchronous orbit, which he originally proposed in 1969.
View on timelineDr. Suomi obtained funding from NASA and NOAA to implement a proof-of-concept system dedicated to measuring and visualizing cloud drift winds. The new computer system had to allow the user to specify the image coordinates of a cloud in at least three successive images. Since the digital images were stored on computer tape, some method was required to map and display coordinates to and from tape. The proof-of-concept system used to demonstrate winds processing was called WINDCO (Lazzara, 1999). WINDCO was a precursor to the Man computer Interactive Data Access System (McIDAS).

View on timelineThe VAS (a second order acronym for VISSR (Visible and Infrared Spin-Scan Radiometer) Atmospheric Sounder) concept was formalized in April 1972 by the SSEC at the University of Wisconsin-Madison in the form of a preliminary instrument specification. Later in 1972 the National Oceanic and Atmospheric Administration (NOAA) requested that the National Aeronautics and Space Administration (NASA) proceed with the development of a VAS instrument.
View on timelineThe McIDAS prototype is functioning daily and provides University of Wisconsin meteorologists with quick and easy access to ATS data. Plans for expansion now being implemented will enable the system to efficiently access and process multispectral image data in many different formats from other spacecraft such as SMS, Mariner, EERTS, ITOS, and ESSA. [From - An interim report on the development of the Man-Computer Interactive Data Access System]
View on timelineThe first generation Man computer Interactive Data Access System (McIDAS) was a single-user system based on a Harris/5 computer. It provided animation, display and analysis of data from geostationary satellites. Later, radar, meteorological observations and forecasts were added to the system. Developed at SSEC, it was the first ever tool to visualize satellite data.
View on timelineThe success of UW-Madison professor Verner Suomi’s camera on the ATS series of satellites led to NASA's Synchronous Meteorological Satellite (SMS) with an infrared camera, allowing scientists to see clouds at night and to estimate their height in the atmosphere.
View on timelineThe GARP Atlantic Tropical Experiment (GATE) began in June 1974 and ended in September 1974. SSEC experiments examined African squall lines during GATE, used satellite images to estimate rainfall over the GATE area, examined the structure of convective storms, studied vertical mass transports in GATE cloud clusters, developed techniques for improved use of satellite data, examined wind sets and continued the development of McIDAS using GATE data. Funding came from NASA, the National Science Foundation and the National Oceanic and Atmospheric Administration (NOAA).

Geostationary operational environmental satellites (GOES) orbit the Earth at 22,000 miles. Developed at the Space Science and Engineering Center (SSEC), UW-Madison and built by Santa Barbara Research Center (SBRC), the instrument would provide high-quality day/night cloud cover data and take radiance-derived temperatures of the earth/atmosphere system.
View on timelineThe second generation Man computer Interactive Data Access System (McIDAS) was implemented in 1978. It used Harris/6 computers networked with high speed communications. The configuration provided a centralized real-time database of satellite imagery and observational weather data
View on timelineSSEC engineers adapted a videocassette recorder to archive digital satellite data in order to solve the difficult problem of recording high-speed digital data from the Geostationary Operational Environmental Satellite (GOES) series of satellites. Video recorders had high bandwidths and long recording times, necessary for recording this type of data. The use of a video cassette recorder as a data recorder was attractive since GOES data have characteristics similar to those of a television signal. SSEC would become, in 1979, the national archive for GOES data.
View on timelineGOES-3 launched on June 16, 1978 aboard a Delta rocket. It was a NASA-developed, NOAA-operated, geosynchronous, and operational spacecraft. The spin-stabilized spacecraft carried five experiments, including the UW-Madison developed Visible Infrared Spin-Scan Radiometer (VISSR) to provide high-quality day/night cloudcover data and to take radiance-derived temperatures of the earth/atmosphere system.
