From the air inside a classroom or a greenhouse to the controlled environment of a space capsule or habitat, the composition and quality of the air we breathe has direct consequences for human health and well-being. Poor air quality can cause or worsen respiratory and cardiovascular conditions, affect crop health, and impact pollinators that agricultural systems depend on. Key atmospheric parameters include:<\/p><ul><li>Particulate matter (PM2.5 and PM10)<\/li><li>Carbon dioxide (CO2) and other gas concentrations<\/li><li>Temperature and humidity<\/li><li>Barometric pressure<\/li><\/ul><p class=\"mb-2 whitespace-pre-wrap\">Monitoring these parameters gives scientists, educators, and citizens the information needed to understand local conditions, whether outdoors in the field, inside a building, or within the enclosed atmosphere of a space habitat, and to make informed decisions about health and the environment.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d524701 elementor-widget elementor-widget-heading\" data-id=\"d524701\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">STELLA-AM: Making Atmospheric Science Accessible<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-1dc92f6 elementor-widget elementor-widget-text-editor\" data-id=\"1dc92f6\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div class=\"relative flex-1 overflow-hidden overflow-y-auto\"><div class=\"relative h-full\"><div class=\"scrollbar-gutter-stable\"><div class=\"flex flex-col pb-9 pt-14 dark:bg-transparent\"><div><div class=\"text-token-text-primary w-full border-0 bg-transparent dark:border-0 dark:bg-transparent\"><div class=\"m-auto justify-center p-4 py-2 md:gap-6\"><div id=\"2d0c6e1d-e326-4ed7-82ca-1452962e6d5e\" class=\"group mx-auto flex flex-1 gap-3 transition-all duration-300 transform-gpu md:max-w-[47rem] xl:max-w-[55rem] focus:outline-none focus:ring-2 focus:ring-border-xheavy message-render\" aria-label=\"Message 14\"><div class=\"relative flex flex-col w-11\/12 agent-turn\"><div class=\"flex flex-col gap-1\"><div class=\"flex max-w-full flex-grow flex-col gap-0\"><div class=\"text-message flex min-h-[20px] flex-col items-start gap-3 overflow-visible [.text-message+&amp;]:mt-5\" dir=\"auto\"><div class=\"markdown prose message-content dark:prose-invert light w-full break-words dark:text-gray-100\"><p class=\"mb-2 whitespace-pre-wrap\">The STELLA-AM instrument (Science and Technology Education for Land\/Life Assessment &#8211; Atmosphere Monitor) is a low-cost, easy-to-build instrument that measures key atmospheric parameters including carbon dioxide, particulate matter, barometric pressure, temperature, humidity, magnetic field, and acceleration.
