1	2	-3	m	wtrop	Wet Tropospheric Correction Computed at mean sea level at the altimeter time-tag from the interpolation of 2 ERA meteorological fields that surround the altimeter time-tag. A wet tropospheric correction must be added (negative value) to the instrument range to correct this range measurement for wet tropospheric range delays of the radar pulse. See TOPEX User Handbook.
