It focuses on airborne measurements to quantify the emissions from landfills in the Los Angeles Basin. Airborne remote sensing data have been used to estimate the emission rate of one particular landfill on four different days.
WebOct 25, 2024 · This image shows a methane plume 2 miles (3 kilometers) long that NASA’s Earth Surface Mineral Dust Source Investigation mission detected southeast of Carlsbad, New Mexico. Methane is a potent greenhouse gas that is much more effective at trapping heat in the atmosphere than carbon dioxide. Credit: NASA/JPL-Caltech WebDec 31, 1994 · Due to its long atmospheric lifetime and relatively homogeneous distribution, any methane signal to be detected through remote sensing is small. The methane attributes of interest are not directly observable, but must be inferred through inversion of the spatially (and perhaps spectrally), integrated signal received by the instrument.
