Short summary
Strong changes in pressure, temperature, and humidity occur when small scientific aircraft ascend through the atmosphere to measure carbon dioxide. These strong changes can produce errors in the carbon dioxide measurements. To avoid these errors, we present a low-cost and simple correction method. This low-complexity method allows more researchers to study atmospheric carbon dioxide, reducing entry barriers in this field.
