Abstract Surface, aircraft, and satellite measurements indicate pervasive early cold season (Augut–September) CO2 emissions across Arctic regions, consistent with increased ecosystem metabolism in plants and soils. A key remaining question is wheth

Abstract Hyperspectral infrared sounding contains information about clouds, which plays an important role in modulating Earth's climate. However, there is a great deal of uncertainty in modeling the radiative effect of clouds due to its complex depen

Remote Visible/Shortwave Infrared (VSWIR) imaging spectroscopy is a powerful tool for measuring the composition of Earth’s surface over wide areas. This compositional information is captured by the spectral surface reflectance, where distinct shape

The retrieval of aerosol and cloud properties such as their optical thickness and/or layer/top height requires the selection of a model that describes their microphysical properties. We demonstrate that, if there is not enough information for an appr

Tropical Tropopause Layer cirrus clouds and their radiative effects represent a major uncertainty in the evaluation of Earth’s energy budget. High altitude aircraft offer an opportunity to provide observations at cirrus cloud altitudes, most common

Atmospheric aerosols play a central role in the Earth’s radiative budget. They represent a significant part of the anthropogenic forcing responsible for climate change. However, uncertainties in the origin and composition of aerosol particles, thei
