Derivation of Land Surface Temperature for Landsat-8 TIRS Using a Split Window Algorithm
Land surface temperature (LST) is one of the most important variables measured by satellite remote sensing. Public domain data are available from the newly operational Landsat-8 Thermal Infrared Sensor (TIRS).

Global Distribution of Water Vapor and Cloud Cover--Sites for High Performance THz Applications
Absorption of terahertz radiation by atmospheric water vapor is a serious impediment for radio astronomy and for long-distance communications. Transmission in the THz regime is dependent almost exclusively on atmospheric precipitable water vapor (PWV ...

Estimating forest parameters from top-of-atmosphere radiance measurements using coupled radiative transfer models [PDF]
The canopy and atmosphere radiative transfer models SLC and MODTRAN were coupled to simulate top-of-atmosphere (TOA) radiance data for 3 Norway spruce stands in Eastern Czech Republic. The simulations fitted the near-nadir CHRIS radiance data well.

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.

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.

Modeling Top of Atmosphere Radiance over Heterogeneous Non-Lambertian Rugged Terrain
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]
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 ...

Due to the complexity and heterogeneity mechanism of aerosol scattering and absorption, there is no systematic operational net surface shortwave radiation (NSSR) retrieval algorithm for considering the forces of different aerosols.
