The Ceilometer Ship Correction (CEILSHIPCOR) VAP is intended to correct the effect of ship motion on the laser measurements, which are intended to be vertically pointing. CEILSHIPCOR is provided as an evaluation product for the MAGIC and ACAPEX campaigns.
Cloud base heights and other variables are corrected to account for the motion (pitch, roll, heave) of the ship. If motion measurements are unavailable, then the values remain uncorrected, however this is reflected in ancillary QC.
