Beginning 4 November 2004, the 89 GHz A-horn developed a permanent problem resulting in a loss of those observations. Consequently, after 3 November 2004, the High_Res_A_Swath data fields contain values of 0.
The Geolocation fields for the High_Res_A_Swath and the High_Res_B_Swath are completely analogous to those of the Low_Res_Swath with 486 observations per scan rather than 243.
The swath attribute fields of the High_Res_A_Swath and the High_Res_B_Swath are identical to those of the Low_Res_Swath except that the Resampled_Channel_Sequence field is omitted because high-resolution swaths have no resampled channels. Also, the Level1A_Channel_Sequence field was modified to describe the order of the elements of the High_Res_A_Swath Level1A_Scan_Chan_Quality_Flag rather than that of the Low_Res_Swath quality flag.
