Visible Infrared Imaging Radiometer Suite (VIIRS) 24-h data are substantially affected by lunar illumination. A new method is proposed to correct this distortion and be able to form a consistent time series. The method has the advantage of being relatively simple in its deployment while at the same time effective. The results show that the proposed method removes periodical illumination noise due to the lunar circle while preserving meaningful information, in the test sites applied. more ...

In the past, the Defense Meteorological Satellite Program Operational Linescan System data have been successfully adjusted based on the presence of vegetation in each pixel. We propose a further adjustment based on radar data obtained by the SeaWinds scatterometer. It is shown that the adjustment results in substantial accuracy gains, measured asincreased correlation with the more accurate Visible Infrared Imaging Radiometer Suite data aswell as with the existing instances of radiance calibrated DSMPOLS data. The proposed adjust-ment is easy to implement. The improvement of the proposed method is particularly significant in arid regions where vegetation is relatively sparse. more ...
