Where can I find spectral response information for the OMI bands?
OMI is a non-scanning wide angle nadir pointing hyper-spectral push broom imaging spectrograph, to observe solar backscatter radiation in the visible and ultraviolet spectral region. The Earth will be viewed in 1560 wavelength bands in the spectral region 270 to 500 nm with a spectral resolution of approximately 0.5 nm. The spectral samplings are grouped into two optical channels, UV & visible (VIS). The UV channel is split into two sub-channels: UV-1 ranging from 270 to 310 nm, and the UV-2 ranging from 310 to 365 nm for stray-light considerations. The VIS-channel ranges from 365 to 500 nm. Two 2-dimensional CCD detectors are used, one for UV-1 & 2 and other for the VIS channel. The nominal integration time of the CCD image is 0.4 sec. To decrease the data rate and increase the signal-noise ratio, onboard binning and co-adding of subsequent CCD images are performed. The number of exposures or images that are averaged is specified by the “binning factor”, which is set by the instrument
