An increasing body of evidence supports the conclusion that electrical variations in the Polar Regions influence atmospheric radiative properties. These influences can be transmitted (1) by the global electric circuit from remote thunderstorms and el

A spectral radiometer located at the South Pole has obtained a long-term record of ground-level solar irradiance at wavelengths from 315 to 600 nm. Data acquired during the sunlit periods from 1992 to 2016 provide information on the scattering proper

Measurements of ground-level visible sunlight (400–600 nm) from Summit, Greenland over the period August 2004 through October 2014 define the attenuation provided by cloudiness, including its dependence on solar elevation and season. The long-term

This work examines the heating and cooling of an urban rooftop using radiative and meteorological measurements plus numerical simulations for the months June through September. Longwave atmospheric radiation accounts for 63.6% of the radiant energy a

Longwave irradiances measured from two sites at different geomagnetic latitudes show different responses to changes in the east-west component of the interplanetary magnetic field (IMF B y ). At Barrow, Alaska, geomagnetic latitude 69-70 o N, neither

This work applies a new model that treats solar and longwave radiative transfer, thermal conduction, and sensible heat transport to quantify the flow of energy across single- and double-pane windows. A set of radiometers based in Chicago, Illinois, o

This research examines a 17-year database of UV-A (320–400 nm) and visible (400–600 nm) solar irradiance obtained by a scanning spectroradiometer located at the South Pole. The goal is to define the variability in solar irradiance reaching the po

We analyze 20 years of daily minimum and maximum air temperature data in the Chicago metropolitan region and propose a parsimonious model that describes their mean function and the space–time covariance structure. The mean function contains a long-
