Personal Solar UV Exposures in Diffuse UV Settings

2004
The previous chapter has described the details of the spectrum of diffuse ambient solar UV radiation in a number of different environments. This chapter outlines the broadband erythemal UV, UVA and the visible irradiances in the shade of trees. The percentage of these irradiances in the shade compared to those in the sun may change with season and the ...

Stray light correction of array spectroradiometers for solar UV measurements.

Applied Optics, 2014
An approach is presented to characterize and correct stray light in spectra measured with array spectroradiometers and caused by out-of-spectral range radiation.

Solar-blind UV region and UV detector development objectives

SPIE Proceedings, 1999
The vulnerability of aircraft to missile attacks is briefly sketched. Aircraft and helicopter defensive electronic self- protection systems against missile attacks including passive and active radar and IR countermeasures are summarized. Radar and IR missile threat warnings are outlined. The development of UV missile threat warning is recounted.

Oxygen vacancy induced Bi2WO6 for the realization of photocatalytic CO2 reduction over the full solar spectrum: from the UV to the NIR region.

Chemical Communications, 2016
Photocatalytic CO2 reduction over the UV-Vis-NIR broad spectrum was realized for the first time. The presence of surface oxygen vacancy defects on Bi2WO6 resulted in significant photocatalytic enhancement over the pristine counterpart under UV and ...

Solar UV and ozone balloon measurements

Advances in Space Research, 1982
Abstract Absolute solar UV spectra were obtained with a 1 4 m spectrometer on a balloon flight from Palestine, Texas on September 23, 1981. This balloon reached a float altitude of 39 km at solar noon. The ozone density profiles derived from these spectra are discussed.

UV observations of macrospicules at the solar limb

Solar Physics, 1989
During the Spacelab 2 mission, the NRL High Resolution Telescope and Spectrograph (HRTS) obtained a time-series of broad-band ultraviolet images of macrospicules at the solar limb inside a polar coronal hole with a temporal resolution of 20 and 60 s. The properties of the macrospicules observed in the Spacelab data are measured and compared with the ...

Air-Stable and Solution-Processable Perovskite Photodetectors for Solar-Blind UV and Visible Light.

Journal of Physical Chemistry Letters, 2015
Stable perovskite CH3NH3PbI3-xClx for a photodetector was prepared through spin-coating of a fluorous polymer as a light protection layer. The best responsivity of photodetector was 14.5 A/W to white light and 7.85 A/W for solar-blind UV light (λ = 254 ...

Effect of cesium chloride modification on the film morphology and UV-induced stability of planar perovskite solar cells

, 2016
The interface modification of perovskite thin films has shown great potential to boost the performance of perovskite solar cells during the last few years. Here we demonstrate that cesium chloride (CsCl) as crystal seeds can markedly enhance the coverage

Effects of solar UV-B radiation on aquatic ecosystems

Advances in Space Research, 1997
Solar UV degrades dissolved organic carbon photolytically so that they can readily be taken up by bacterioplankton. On the other hand solar UV radiation inhibits bacterioplankton activity. Bacterioplankton productivity is far greater than previously thought and is comparable to phytoplankton primary productivity.
