The libRadtran software package is a suite of tools for radiative transfer calculations in the
Earth's atmosphere. Its main tool is the uvspec program. It may be used to compute …

Representative values of the atmospheric NO 2 photolysis frequency,(j (NO 2)), are required
for the adequate calculation and interpretation of NO and NO 2 concentrations and …

Depletion of stratospheric ozone over the Arctic can reduce normally high winter and spring
ozone levels and allow more ultraviolet (UV) radiation to reach the surface of the earth …

Ultraviolet radiation is the key factor driving tropospheric photochemistry. It is strongly
modulated by clouds and aerosols. A quantitative understanding of the radiation field and its …

A six-channel moderate-bandwidth filter instrument for measurement of UV and visible
radiation has been developed. The characteristics of the instrument are described, including …

Spectral measurements of solar ultraviolet (UV) radiation have been made at several ground-
based locations and for more than 10 yr at some sites. These measurements are important …

The presence of an organic film on a cloud droplet or aqueous aerosol particle has the
potential to alter the chemical, optical and physical properties of the droplet or particle. In the …

Solar irradiance spectral measurements were performed during a total solar eclipse. The
spectral effect of the limb darkening to the global, direct irradiance and actinic flux …

In the late 1960s and early 1970s, concerns were raised regarding the vulnerability of
stratospheric ozone to anthropogenic activities and the consequential increase of ultraviolet …

In September 2002, the first INSPECTRO campaign to study the influence of clouds on the
spectral actinic flux in the lower troposphere was carried out in East Anglia, England …
