Shortwave ultraviolet radiation in operating rooms

The Journal of Bone and Joint Surgery. British volume, 1989
We have evaluated the effect of shortwave ultraviolet radiation on bacterial levels in an operating theatre, both in experimental conditions and during 20 hip operations. When compared with the use of sham blue light, there was a significant reduction in the number of bacteria.

Incident Shortwave Radiation

2013
Incident shortwave radiation (ISR), also known as insolation, is referred to as total solar irradiance incident at the Earth’s surface and is an essential parameter in land surface radiation budget and many land surface process models. This chapter provides a primary introduction to the GLASS ISR product by discussing the algorithm, validation, and ...

Estimation of Surface Net Radiation from Solar Shortwave Radiation Measurements

IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008
This study develops a method to estimate surface daytime net radiation (Rn) from solar shortwave radiation measurements with help of the conventional meteorological observations and vegetation indices from satellite. Data collected at twenty-two sites in the U.S.

Net Surface Shortwave Radiation Retrieval Using Viirs Data

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
The Net Surface Shortwave Radiation (NSSR) at the Earth's surface drives evapotranspiration, photosynthesis and other physical and biological processes. The primary objective of this study is to estimate NSSR using multispectral narrowband data of the National Polar-orbiting Operational Environmental Satellite System (NPOESS) Visible Infrared Imaging ...

Climatology and trends of downward shortwave radiation over Brazil

Atmospheric Research, 2021
Abstract The solar downward shortwave radiation (DSWR) is the primary source of energy to Earth and a driving forcing for sensible/latent heat and water vapor fluxes over the terrestrial ecosystems and the atmosphere. Evaluation of the DSWR spatiotemporal patterns and trends is crucial to the understanding of weather and climate variability.

Studies of Shortwave Solar Radiation in the USSR

Applied Optics, 1967
A history is presented of measurements of solar vacuum uv and soft x radiation made by rocket and satellite-borne instruments in the U.S.S.R. The origin and mechanism of the production of solar x rays are discussed.

Dust Accumulation Biases in PIRATA Shortwave Radiation Records*

Journal of Atmospheric and Oceanic Technology, 2013
Abstract Long-term and direct measurements of surface shortwave radiation (SWR) have been recorded by the Prediction and Research Moored Array in the Tropical Atlantic (PIRATA) since 1997. Previous studies have shown that African dust, transported westward from the Sahara and Sahel regions, can accumulate on mooring SWR sensors in the ...

Relationships of photosynthetically active radiation and shortwave irradiance

Agricultural Meteorology, 1976
Abstract Measurements of photosynthetically active radiation (400–700 nm) and shortwave irradiance (ca. 300–2,000 nm) were made over a 14-month period at College Station, Texas. The proportion of photosynthetically active radiation changed with intensity of incident irradiance and length of photoperiod.
