Fertilizer application and manure management inevitably release nitrogen-containing gases, such as ammonia, nitrous oxide, and nitrogen oxides, in addition to methane and other carbon-containing gases. Agricultural emissions are challenging\u00a0to quantify, and ground monitoring networks are sparse in rural areas.\u00a0FarmFlux will deploy cutting-edge airborne instruments and techniques to fill this important and understudied gap in climate science and atmospheric research.<\/p>\n<h2 class=\"wp-block-heading\"><strong>Research questions<\/strong><\/h2>\n<p class=\"wp-block-paragraph\">FarmFlux researchers will address four primary science questions:\u00a0<\/p>\n<ul class=\"wp-block-list\">\n<li>What is the magnitude of emissions downwind of animal feeding operations, and how do they vary with farm practices and weather?<\/li>\n<li>How do gases exchange over major crop systems, and how do these fluxes connect to farm practices, crop cover, and soil moisture? \u00a0<\/li>\n<li>What are the physical and chemical properties of particulate matter in agricultural regions?<\/li>\n<li>How do agricultural emissions impact regional air quality, and how can we advance new satellite data applications over agricultural areas?<\/li>\n<\/ul>\n<h2 class=\"wp-block-heading\"><strong>Science in Action\u00a0<\/strong><\/h2>\n<p class=\"wp-block-paragraph\">The technology has evolved to meet this challenge. Airborne instruments are faster, more precise, and more compact than they were a decade ago. Instruments will be mounted onboard two aircraft: the King Air A200 will fly over livestock operations, and the NASA P-3 will fly over crop systems. Observations will feed air quality models used to forecast near-term air quality and simulate strategies for long-term air quality improvement.<\/p>\n<h2 class=\"wp-block-heading\">Explore other EVS-4 Campaigns<\/h2>\n<p class=\"wp-block-paragraph\">The EVS-4 missions: <a target=\"_blank\" href=\"https:\/\/science.nasa.gov\/mission\/evs-4\/farm-flux\">FARMFLUX<\/a> | <a target=\"_blank\" href=\"https:\/\/science.nasa.gov\/mission\/evs-4\/forte\">FORTE<\/a> | <a target=\"_blank\" href=\"https:\/\/science.nasa.gov\/mission\/evs-4\/hamaq\">HAMAQ<\/a> | <a target=\"_blank\" href=\"https:\/\/science.nasa.gov\/mission\/evs-4\/inspyre\">INSPYRE<\/a> | <a target=\"_blank\" href=\"https:\/\/science.nasa.gov\/mission\/evs-4\/lacce\">LACCE<\/a> | <a target=\"_blank\" href=\"https:\/\/science.nasa.gov\/mission\/evs-4\/snow4flow\">SNOW4FLOW<\/a><\/p>\n<div id=\"\" class=\"hds-topic-cards nasa-gb-align-full maxw-full width-full padding-y-6 padding-x-3 color-mode-dark hds-module hds-module-full alignfull wp-block-nasa-blocks-topic-cards\">\n<div class=\"grid-container grid-container-block-lg padding-x-0\">\n<div class=\"grid-row flex-align-center margin-bottom-3\">\n<div class=\"desktop:grid-col-8 margin-bottom-2 desktop:margin-bottom-0\">\n<p>Keep Exploring<\/p>\n<h2 class=\"heading-36 line-height-sm\">Discover More Topics From NASA<\/h2>\n<\/p><\/div><\/div><\/div><\/div>\n<\/div>\n<\/div>\n<p><br \/>\n<br \/><a href=\"https:\/\/science.nasa.gov\/mission\/evs-4\/farm-flux\/?rand=6382\" target=\"_blank\">Source link <\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Background Agriculture is the single largest source of ammonia, methane, and nitrous oxide in the United States, and it is a rising source of other atmospheric emissions.
