”...no one knows just how the complicated climate system of Earth’s atmosphere will respond to the small forcings [of GHGs].”

In a pre-proof study from the Journal of Quantitative Spectroscopy and Radiative Transfer, researchers used artificial intelligence (AI) models to effectively predict the emissivity of functionalized surfaces produced by the femtosecond laser surface processing method.

A recent paper illustrated a low-cost digitally integrated LiDAR with TDC that is completely FPGA-controlled and processed in a low-end FPGA chip with constrained configurable logic block resources.

Nitrous oxide (N2 O) is the third most abundant anthropogenous greenhouse gas (after carbon dioxide and methane), with a long atmospheric lifetime and a continuously increasing concentration due to human activities, making it an important gas to monitor. In this work, we present a new method to retrieve N2 O concentration profiles (with up to two degrees of freedom) from each cloud-free satellite observation by the Infrared Atmospheric Sounding Interferometer (IASI), using spectral micro-windows in the N2 O ν3 band, the Radiative Transfer for TOVS (RTTOV) tools and the Tikhonov regularization...

This study demonstrates a compact deep UV Raman spatial heterodyne spectrometer for biologics analysis.
