DSI-6323 was included in ... the larger Comprehensive Aerological Data Set (CARDS) Upper Air data set, DSI-6305, which was quality controlled as it was assembled from many smaller data sets. DSI-6323 itself was not quality controlled at the NCDC. Most users should not request DSI-6323, but should instead opt for DSI-6305.
