Field 27 should be a scalar lin_shear, and field 43 should be a vector
lin_shear_var_z.
(This is the same problem identified by Chiara over a year ago.)

Dear colleagues, with some delay the reprocessed orbit 2081 with new non-linearity correction and ice-correction is ready. Look at the previous word document for details. [ftp details removed] for each sweep in each channel there are two ascii files one for the radiances and one for NESR. The first line in the files is text (not usefull for you) the second: xstart the third: xend the fourth: deltax the fifth: npoints the followinglines radiance or NESR after the spectral data: one line (only for radiance file not for NESR file) with: processing date (level 1b generation), measurement date and time, alditude, latitude and longitude of tangent. three further lines which are not important. The file names contain the orbit number, channel(A is denoted as A1), sweep index, sweep dir (0=forw, 1=rev) and other information not relevant here. If you have questions: Gottfried Schwarz has already processed some scans

Sorry to tell you that the level 1a numbering of sweeps is not linked to the sweep IDs or scan IDs you are used to. Thus, the only chance you have to identify the appropriate level 1a sweep IDs you should check time or lat/lon. The only thing we can tell you is that level 1a sweep IDs are numbered consecutively as they are measured. Some numbers are missing since they corrspond to offset measurements which are also counted by the level 1a sweep IDs, but, of course, are missing in the scene radiance files. Level 1a IDs 0 to 6 correspond to the seven lowermost tangent heights of an incomplete scan at the beginning of the orbit. IDs 7 to 12 are offset sweeps, and complete scans (of 17 sweeps each) start with ID 13. Every 5 complete scans they are again interrupted by blocks of 6 offset sweeps. Hope that helps Greetings, Manfred + Georg
