IR calibration jump

[Adam Dybbroe]

I have done a small analysis of the scene from yesterday where we
observed some significant jumps in IR Tbs of the M-bands.
I have a pdf file with some images at ftp.smhi.se/busers/adybbroe/VIIRS

Here is one plot showing the across track mean TB for M15 and M16 as a
function of swath position("detector scanline").

You see that it is surely something that will affect quantitative
applications! The jump is around 20K!!!

Best regards
Adam
