Abstract:

This memorandum presents measurements of marine surface meteorology, sea-surface temperature and atmospheric profiles taken from the RV Alliance between 1 October and 9 November, 1991. These are to be used to study the accuracy with which sea-surface temperature and atmospheric precipitable water can be measured by infrared and microwave radio meters on earth observation satellites. The measurements were taken on passage from Amsterdam to La Spezia, during two short instrument trials cruises, and on a non-interference basis during the cruise SPG 191 in the western Mediterranean Sea. The calibrated measurements of sea and air temperature, relative humidity, and long- and short-wave downwelling surface radiation are presented here as time series, beginning at about 15002 on October 1 and continuing until about 19002 on November 8, with the exceptions of days when the ship was in port at La Spezia. True winds, net long-wave surface radiation flux, and the turbulent air-sea exchanges of sensible and latent heat have been calculated and are presented. Profiles of atmospheric temperature and humidity are also displayed, and the ships track is given in a graphical form. This data report also serves to record the environmental conditions in which the other activities on the Alliance took place.
