Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 10, October 2025.Abstract Climate change‐induced shrub expansion in the Arctic feeds back on climate by reducing surface albedo. Vegetation dynamics are typically monitored by tracking the evolution of vegetation indices, such as normalized difference vegetation index (NDVI), derived from satellite imagery in processes known as greening or browning.

Modeling Top of Atmosphere Radiance over Heterogeneous Non-Lambertian Rugged Terrain
Remote Sensing, 2015 Topography affects the fraction of direct and diffuse radiation received on a pixel and changes the sun–target–sensor geometry, resulting in variations in the observed radiance.

A new simplified approach for simultaneous retrieval of SO2 and ash content of tropospheric volcanic clouds: an application to the Mt Etna volcano [PDF]
Atmospheric Measurement Techniques, 2013 A new procedure is presented for simultaneous estimation of SO2 and ash abundance in a volcanic plume, using thermal infrared (TIR) MODIS data. Plume altitude and temperature are the only two input parameters required to run the procedure, while surface ...

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 18, 28 September 2025.Abstract We analyze lightning optical emissions and their production of different chemical species with particular emphasis on NOx ${\text{NO}}_{x}$ and HOx ${\text{HO}}_{x}$. We calculate synthetic lightning spectra with inputs from an electrodynamical model of hot air lightning plasmas.

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 12, 28 June 2025.Abstract Spectrally dependent emission by the surface (i.e., surface spectral emissivity) is commonly ignored by current climate models. Surface spectral emissivity matters more in cold and dry environments than in hot and humid environments. Recent modeling studies confirmed that, for current climate simulations, this process affects the polar climate
