Surface UV Irradiance from OMI on EOS-Aura
نویسندگان
چکیده
The Ozone Monitoring Instrument (OMI) onboard the NASA EOS Aura spacecraft is a nadir viewing spectrometer that measures solar reflected and backscattered light in a selected range of the ultraviolet and visible spectrum. The instrument has a 2600 km wide viewing swath and it is capable of daily, global contiguous mapping. We have developed and implemented a surface ultraviolet irradiance algorithm for OMI that produces noontime surface spectral UV irradiance estimates at four wavelengths (305, 310, 324, 380 nm). Additionally, noontime erythemal dose rate and the erythemal daily dose are estimated. The paper includes a brief overview of the OMI surface UV algorithm, current processing status, recent validation results and plans for further development of the surface UV algorithm.

Measurements of UV irradiance within the area of one satellite pixel
A measurement campaign was performed in the region of Vienna and its surroundings from May to July 2007. Within the scope of this campaign erythemal UV was measured at six ground stations within a radius of 30 km. First, the homogeneity of the UV levels within the area of one satellite pixel was studied. Second, the ground UV was compared to ground UV retrieved by the ozone monitoring instrumen...
