Global surface ultraviolet radiation climatology from TOMS and ERBE data

Long-term global earth surface ultraviolet radiation exposure derived from ISCCP and TOMS satellite measurements

A long-term (1983–2000) global dataset of Earth’s surface daily-integrated UV exposure was developed from a combination of ISCCP-D1 3 h reflectance measurements (in order to resolve the diurnal variation of cloud conditions) and TOMS total ozone amount. The inversion algorithm developed in our previous study was employed with modifications addressing the conversion of visible reflectance to UV ...

Ultraviolet climatology over Argentina

[1] Satellite-derived climatologies of UV index (UVI) and erythemal daily dose were determined for Argentina at a geographical resolution of 0.5 latitude by 0.5 longitude. Total Ozone Mapping Spectrometer climatology of key input parameters was used to calculate the clear-sky ground-level solar UV irradiance. NASA Surface meteorology and Solar Energy cloud cover data were used to determine the ...

Earth surface reflectance climatology from 3 years of OMI data

[1] Global maps of the Earth’s surface Lambertian equivalent reflectance (LER) are constructed using 3 years of Ozone Monitoring Instrument (OMI) measurements obtained between October 2004 and October 2007 at 23 wavelengths between 328 and 500 nm. The maps are constructed on a 0.5 by 0.5 longitude-latitude grid for each calendar month using an algorithm based on temporal histograms of the obser...

Surface Ultraviolet Radiation: Past, Present, and Future

Recent Climatology, Variability, and Trends in Global Surface Humidity

In situ observations of surface air and dewpoint temperatures and air pressure from over 15 000 weather stations and from ships are used to calculate surface specific (q) and relative (RH) humidity over the globe (60°S–75°N) from December 1975 to spring 2005. Seasonal and interannual variations and linear trends are analyzed in relation to observed surface temperature (T) changes and simulated ...
