For imaging instruments that are in space looking toward the Earth, there are a variety of nuisance signals that can get in the way of performing certain imaging tasks, such as reflections from clouds, reflections from the ground, and emissions from

Orbital sensors to monitor global climate change during the next decade require low-drift rates for onboard thermometry, which is currently unattainable without on-orbit recalibration. Phase-change materials (PCMs), such as those that make up the ITS

Fourier Transform Spectroscopy and Hyperspectral Imaging and Sounding of the Environment.
Far-infrared radiance from the atmosphere was observed at Earth’s surface at Cerro Toco, Chile, and Table Mountain, CA with the NASA FIRST instrument. Measurements are compared with model calculations, showing agreement within their combined uncert

Many organizations, including Space Dynamics Laboratory, have built blackbodies with calculated emissivities of 0.995 to 0.9999 and estimated radiance temperature uncertainties of a few hundred mK or less. However, the calculated performance has gene
