It will be based out of the Osan U.S. Air Base in South Korea.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EWhile the monsoon is most often associated with the deluge of moisture it brings to the Asian continent, the ACCLIP research team is not focused on the rain that comes down. Instead, they\u0026rsquo;re interested in what the powerful circulation of the monsoon pulls back up. Since the monsoon occurs over some of the regions in the world with the worst air quality, scientists think a wide range of pollutants may get sucked high into the atmosphere. The resulting redistribution of chemicals \u0026mdash; and their reactions with one another \u0026mdash; can have a significant impact on the climate.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;In recent decades, satellites have revealed that the monsoon creates a distinct layer of chemicals about 10 miles above the Earth, but we know very little about its composition and evolution,\u0026rdquo; said NCAR scientist Laura Pan, an ACCLIP principal investigator. \u0026ldquo;ACCLIP will give us an opportunity to sample what\u0026rsquo;s there, but we know that whatever its composition, it connects to the climate.\u0026rdquo;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EACCLIP is funded by NSF; NASA; NOAA; and the Office of Naval Research. Additional funding comes from agencies in Europe and Asia.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Ch3\u003EImpacts on climate, ozone\u003C\/h3\u003E\r\n\r\n\u003Cp\u003EACCLIP\u0026rsquo;s scientific objectives include improving our understanding of how the Asian summer monsoon transports air from the ground to the top of the troposphere and bottom of the stratosphere miles above Earth\u0026rsquo;s surface, as well as what chemicals are contained in that air.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe researchers also want to understand how those chemicals react once they are lofted up. For example, some chemical species can transform into aerosols, or tiny particles, once they reach the upper troposphere and lower stratosphere. These aerosols can reflect the sun\u0026rsquo;s light back into space, cooling the Earth. Other aerosols, known as \u0026ldquo;black carbon\u0026rdquo;, originate from combustion at the surface, and these aerosols will absorb the sun\u0026rsquo;s radiation and produce a heating effect. Aerosols, as well as water vapor that is also sucked up by the monsoon, can affect cloud formation and brightness, which also impacts the climate. The monsoon may also redistribute relatively short-lived greenhouse gases, such as methane, and ozone-depleting substances, such as chlorinated solvents.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EFinally, ACCLIP researchers are interested in studying how the pollutants pulled up by the monsoon may affect ozone chemistry in the region of the atmosphere where the protective ozone layer forms.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003ETo answer these questions, the ACCLIP team will use two research aircraft outfitted with a bevy of scientific instruments. The NSF\/NCAR Gulfstream V will fly at a lower altitude where it can sample the air as it\u0026rsquo;s being circulated by the monsoon, and the NASA WB-57 will fly higher where it can observe the layer of chemicals that make it into the lower stratosphere from the monsoon.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe research team will also use a group of detailed computer models of chemical transport to guide their flights and test their hypotheses. The results from ACCLIP will ultimately be used to improve these complex models.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Ch3\u003EGlobal participation\u003C\/h3\u003E\r\n\r\n\u003Cp\u003EThe broad participation in ACCLIP \u0026mdash; globally, more than 30 institutions are involved in the month-long project \u0026mdash; speaks to the strong scientific interest in the project. In fact, researchers, including Pan, have been working for more than a decade to get a field campaign focused on the Asian summer monsoon up and running. These efforts ran into a number of logistical challenges that slowed the effort, including the COVID-19 pandemic. The mission is now clear to move forward at a U.S. Air Force Base in South Korea. NCAR project managers and engineers are handling the logistics related to the GV and the instruments onboard.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;For many years, there has been a huge amount of interest in a field campaign to study the Asian summer monsoon because it\u0026rsquo;s such an important driver of the weather and climate in the northern hemisphere and beyond,\u0026rdquo; Pan said. \u0026ldquo;We are thrilled to finally be on our way and grateful to all our institutional partners who have contributed their instruments and expertise to make ACCLIP a success.\u0026rdquo;\u003C\/p\u003E\r\n\u003C\/div\u003E\r\n\u003C\/div\u003E\r\n\u003C\/div\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":[{"value":"Field campaign to probe impacts of chemicals redistributed by the Asian monsoon"}],"field_summary":[{"value":"\u003Cp\u003EThe Asian Summer Monsoon Chemical and CLimate Impact Project (ACCLIP) will allow a team of international scientists to study how the Asian summer monsoon \u0026mdash; one of the largest and most important meteorological patterns in the world \u0026mdash; affects atmospheric chemistry and global climate.\u003C\/p\u003E\r\n","format":"limited_html"}],"field_summary_sentence":[{"value":"A team of international scientists will study how the Asian summer monsoon \u2014 one of the largest and most important meteorological patterns in the world \u2014 affects atmospheric chemistry and global climate.
