ITP 77 Data Processing

The 2366 profiles that were recovered from the ITP were processed according to the procedures described in the ITP Updated Data Processing Procedures. [While only the first 1694 profiles were transmitted due to a software error, recovery of the profiler provided another 672 profiles that were stored internally.] The processing parameters are shown in the figures to the right. The processing procedures for the MAVS current probe are described in Cole et al. (2015).

See the Data Products tab to the left for descriptions of the three levels (I, II, III) of data processing and to access all data.
