![]() ![]() 3 The solar constant is a conventional measure of mean TSI at a distance of one astronomical unit (AU). ![]() It is measured perpendicular to the incoming sunlight. A system and its diagram at the same time, Solar Flux Recordings, returns us to the world we inhabit and underlines the bonds which link us to the environment and its technologies. Total solar irradiance (TSI) is a measure of the solar power over all wavelengths per unit area incident on the Earth's upper atmosphere. Beyond the cinematographic flow of succeeding and overlaying images each group refers to a specific position of the sun which is reached only once during the exhibition period: represented by the specific orientation of the inclined glass panels and designated by a metal plaque on the floor, the sculptures become recordings of this performative event. These spatial drawings made of slight metal lines and colored glass panels are reflected on the pavement, projected and animated by the sun. Under the sweeping ceiling of the glass palace nine sculptural groups are displayed, condensing the airy space, each of them composed of elements taken from the architectural vocabulary of the Palacio. And because this measurement can be made reliably and accurately from the ground in all weather conditions, it is a very robust data set with few gaps or calibration issues.Solar Flux Recordings is a site-specific installation conceived for the Palacio de Cristal which brings together architecture and landscape in a performative piece activated and conducted by the sun. Many Ultra-Violet emissions that affect the stratosphere and ozone also correlate with the F10.7 index. ![]() The Extreme UltraViolet (EUV) emissions that impact the ionosphere and modify the upper atmosphere track well with the F10.7 index. Because it comes from the chromosphere and corona of the sun, it tracks other important emissions that form in the same regions of the solar atmosphere. Because it is a long record, it provides climatology of solar activity over six solar cycles. The F10.7 Index has proven very valuable in specifying and forecasting space weather. Further information about Canada's solar weather monitoring services may be found at. These F10.7 measurements are provided courtesy of the National Research Council Canada in partnership with the Natural Resources Canada. The purpose of the predictions is to provide future statistical estimates of sunspot number, solar radio 10.7 cm flux (F10. Reported in “solar flux units”, (s.f.u.), the F10.7 can vary from below 50 s.f.u., to above 300 s.f.u., over the course of a solar cycle. Unlike many solar indices, the F10.7 radio flux can easily be measured reliably on a day-to-day basis from the Earth’s surface, in all types of weather. The F10.7 has been measured consistently in Canada since 1947, first at Ottawa, Ontario and then at the Penticton Radio Observatory in British Columbia, Canada. The F10.7 correlates well with the sunspot number as well as a number of UltraViolet (UV) and visible solar irradiance records. The F10.7 radio emissions originates high in the chromosphere and low in the corona of the solar atmosphere. Often called the F10.7 index, it is one of the longest running records of solar activity. Utilizing both an innovative optical design and dual-axis tracking, the FOCUS maximizes solar energy capture. The FOCUS provides a clean, inexpensive source of thermal energy for a wide range of applications, including industrial process heat, space heating and cooling, hot water, water desalination and purification, and remote and distributed power applications. The solar radio flux at 10.7 cm (2800 MHz) is an excellent indicator of solar activity. Highly Efficient Solar Thermal Energy Technology. ![]()
