At its start, the festival took place in June for the summer solstice. Now, it marks the end of summer.<\/p>\r\n<p class=\"Body\">Attendees set up a temporary metropolis, Black Rock City (BRC), to participate in community and civic life and connect with nature. The site\u2019s flat, arid, vegetation-free playa also proved perfect for climate research.<\/p>\r\n<p class=\"Body\">\u201cThe frictional properties of the surface are extremely small prior to the construction of the city, and there are no sources or sinks of carbon dioxide (CO<sub>2<\/sub>) from vegetation, no transpiration, and very little evaporation from the dry lakebed sediment,\u201d Oliphant said.<\/p>\r\n<p class=\"Body\">With so little impact to the atmosphere before people arrive, Oliphant and his research team could accurately measure the impacts of human activity. They investigated the changing micrometeorological impact of BRC by measuring surface energy and CO<sub>2<\/sub> emissions. They measured surface roughness using wind speed profiles and three-dimensional sonic anemometers. Then, they modeled the roughness in a <a href=\"https:\/\/www.esri.com\/en-us\/what-is-gis\/overview\">geographic information system (GIS)<\/a>.<\/p>\r\n<p class=\"Body\">\u201cWind speed profiles were used to determine the changing surface roughness and validate the GIS modeling,\u201d Oliphant said. \u201cThe surface energy balance was measured to determine the impacts of the built city on surface heat fluxes, and temperature measurements were made to determine the urban heat island status. Surface-atmosphere CO<sub>2<\/sub> fluxes were measured to determine urban carbon emissions.\u201d<\/p>"},{"acf_fc_layout":"image","image":361962,"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"<h3 class=\"Body\"><b>Sensor Towers on Site<\/b><\/h3>\r\n<p class=\"Body\">For this project, Oliphant and his research team used the 30-meter-tall mobile micrometeorological tower called the <a href=\"https:\/\/journals.ametsoc.org\/bams\/article\/95\/11\/1713\/90319\/The-California-State-University-Mobile-Atmospheric\">California State University-Mobile Atmospheric Profiling System<\/a> (CSU-MAPS). The tower is equipped with wind speed, temperature, and radiation sensors. It also has an eddy covariance system that uses a high-frequency gas analyzer and a three-dimensional sonic anemometer to determine fluxes of CO<sub>2, <\/sub>water vapor, and heat on the surface and in the atmosphere.<\/p>\r\n<p class=\"Body\">The tower went up prior to the start of the 2013 festival, and the team made measurements throughout the event. A smaller, similarly equipped tower was deployed outside of the city in the open playa to provide baseline measurements. Researchers took turns riding an instrumented bicycle around the area to regularly measure temperature profiles.<\/p>"},{"acf_fc_layout":"gallery","gallery_images":[368222,368232,368242,368252]},{"acf_fc_layout":"content","content":"<p class=\"Body\">The team took measurements for 12 days\u2014before people arrived, during construction and throughout the event, and after the event concluded.

Because there were no such surfaces to absorb the sun\u2019s heat in BRC, there was no subsequent additional release of heat at night.<\/p>"},{"acf_fc_layout":"image","image":361982,"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"<p class=\"Body\">Interestingly, the amount of carbon dioxide from the breath of attendees far exceeded emissions from transportation, which won\u2019t be true of any other city. However, these findings will help inform environmental impact assessments for other geographies and gatherings.<\/p>\r\n<p class=\"Body\">Because BRC\u2019s urban design and building elements are similar to those found in other informal settlements\u2014such as refugee camps, shanty towns, or favelas\u2014the finding can support research in those areas. <span lang=\"IT\">Oliphant said,
