The Marine W-band (95 GHz) ARM Cloud radar (MWACR) Ship Correction (MWACRSHIPCOR) VAP is intended to correct the effect of ship motion on the radar measurements, which are intended to be vertically pointing. MWACRSHIPCOR is provided as an evaluation product for the MAGIC, MARCUS, and ACAPEX campaigns. The MWACR is installed on a stable table, so only the mean Doppler velocity must be corrected for the heave of the ship. A source variable indicates whether the mean Doppler velocity is corrected using the heave velocity from the SEANAV INS instrument (default) or the MWACR itself. In the event that no heave velocity is available, an indication is made in the source variable and the mean Doppler velocity remains uncorrected.
