Introduction. Epochs of widespread plains emplacement on Venus would have significantly perturbed atmospheric inventories of water and sulfur gases. These gases are potent infrared absorbers that act preferentially to block outgoing thermal radiation within carbon dioxide spectral windows. Small changes in their abundances can significantly alter the efficiency of the Venus atmospheric greenhou...

Traditional methods for remote sensing of urban surface temperatures (Tsurf) are subject to a suite of temporal and geometric biases. The effect of these biases on our ability to characterize the true geometric and temporal nature of urban Tsurf is currently unknown, but is certainly nontrivial. To quantify and overcome these biases, we present a method to retrieve time-continuous hemispherical...
