Abstract:

Along-track measurements made on board the R/V Walton Smith as part of the LASER experiment during January-February 2016 in the northern Gulf of Mexico. Data includes meteorological flux measurements made from twin masts mounted on the bow of the R/V Walton Smith, water surface elevation measurements made from an array of Ultrasonic Distance Meters, and standard ship-board data provided from the R/V Walton Smith UDAS.

Purpose:

The purpose of this data set is to capture the general atmospheric surface layer conditions (in the context of the R/V Walton Smith) during the entirety of the LASER campaign.

Each 10 minute segment was passed through several quality control measures and represents data that: did not experience a change in heading > 40 degrees during the 10 minutes, did not observe wind coming from the aft quadrants of the ship, and did not experience any data interruptions longer than 30 seconds. All raw data was sampled at 20 Hz and then subsampled to 16 Hz for processing. All winds have been motion corrected and adjusted to account for vessel translation. Before motion correction, all data were passed through a despiking routine to remove outlier data. The heading relative to wind direction flag is defined as either 0, 1, or 2. 0 indicates that the wind is coming from within 20 degrees of the vessel heading. 1 indicates the wind is coming from the starboard quarter out to 90 degrees off the starboard beam. 2 indicates the same, but for the port side of the vessel.|The meteorological masts were mounted on the starboard and port prows on the bow of the R/V Walton Smith (a SWATH vessel). Each mast was equipped with a vertical profile of anemometers. The port tower is #1 and the starboard tower is #2. The anemometers are coded from bottom to top of the profile 1-3. The 1 and 2 anemometers on both towers were RM Young 3D sonic anemometers. The 3 anemometers on each tower were Campbell Scientific IRGASONs. The UDMs were arranged with one sensor on each prow, and then 3 sensors arranged in a triplet configuration on a centerline truss mounted in between the two prows and extending ~1 m forward of the furthest edge of the prows. 6-degree vessel motion was acquired from a motion pack fastened to a bench in the R/V Walton Smith scientific lab. A GPS and magnetometer (1 Hz) were also deployed and used for all of the data processing. All systems were synced using a local NTP server.|Raw data sampled at 20 Hz, processed data was subsampled to 16 Hz, and then averaged over 10 minutes. The minimum spacing between successive time stamps in the data set is 10 minutes.||
