Why does the format of the Level II data need to change in Build 10?
REPLY: We need to change the format because the legacy “MSG1” format does not support Super Resolution unless radials become segmented (2432 block segments) and it does not support Dual Polarization Level II data. Thus, we need to change the message format by Build 11, when Dual Polarization data will become available, to “MSG31.” We believe it is better to make these changes in one build rather than to implement them separately in two consecutive software builds.
