Observations are made from any given position on the ship's track/route. Measurements include date, time, position, mean sea level pressure, air temperature, dew-point temperature, wind speed, wind direction, sea surface temperature (SST), visibility, clouds, wind wave period and height, present weather, past weather, pressure tendency and swell direction, period and height. Due to the nature of this data there will often be gaps in the dataset.
