ARM-standard Meteorological Instrumentation, Marine (marinemet)
Browse DataA ship is a difficult place to take meaningful meteorological measurements. Meteorological measurements in this context are the basic quantities necessary to define the wind, temperature, humidity, barometric pressure, and rainfall. We seek to make these measurements to achieve climate accuracy in representation of conditions over the ocean without errors caused by ship effects.
A ship has severe flow distortion. It is a heat island with smoke contamination, shadows, and reflecting surfaces. Therefore, the marine meteorological instrumentation combines proven weather instruments at selected locations on the ship, underway calibrations, and extensive post analysis in order to derive the necessary data quality. Often, redundant sensors are deployed at different locations and their data merged according to relative winds and other conditions.
Measurements
Barometric pressure mean, from the Vaisala WXT520 mounted on the port side of the met boom
Rain intensity mean, from the Vaisala WXT520 mounted on the port side of the met boom
Relative humidity mean, from the T/RH sensor in a forced ventilator (Young 43502) mounted on the met boom
Relative wind direction vector mean, from the wind monitor mounted at the peak of the ship mast
