The campaign was designed to observe key atmospheric and ocean parameters at an existing offshore platform in the proximity of the Massachusetts and Rhode Island Wind Energy Areas. The campaign supported the purchase and installation of a LIDAR wind profiler, two cup anemometers and a wind direction vane at the MVCO Air-Sea Interaction Tower (ASIT). These instruments were installed and operated by WHOI and validated by UL-AWS Truepower following a MetOcean Measurement Plan created by UL-AWST, WHOI, and the MassCEC. All instruments were installed on WHOI's offshore tower in the fall of 2016 and operated continuously, as possible, through the end of 2020. After this time the project transitioned to become the MetOcean Reference Site (MORS-1), supported by the National Offshore Wind Research and Development Consortium (NOWRDC). In fall 2021, a second UL-AWS Truepower validated LIDAR wind profiler was purchased and installed at WHOI's offshore tower. After a validation period, the original lidar was moved to a secondary land based site in Nantucket, MA.' DESCRIPTION = 'A LEOSPHERE WINDCUBE v2 was acquired from NRG Systems and deployed at WHOI's Air Sea Interaction Tower (ASIT). The WINDCUBE instrument is an industry approved LIDAR system for use in Wind Energy Resource Characterization studies. The choice of sensor was made in consultation with UL-AWS Truepower, the wind energy consultant advising MassCEC on its MetOcean Initiative. The lidar, serial number WLS7-436, was a leased model owned by NRG, the U.S. distributor for Leosphere. The instrument was installed at the platform level of the tower along an existing walkway that extends to the southwest, into the prevailing summer time wind direction relative to the center of the tower structure. The lidar connects directly to the ASIT's power and communications systems. Two separate deployments of the lidar were made as part of the study period. The first deployment spanned Oct. 7, 2016 to Dec. 28, 2018. The second deployment spanned Oct. 20, 2019 to Oct. 7, 2021. During the campaign period, the lidar was validated three times by NRG and once against an approved Tall Tower (see validation information). In 2021, a second wind profiling lidar was acquired from NRG Systems. After discussion with wind industry professionals and manufacturers, the decision was made to purchase a Zephir Ltd. ZX 300M Lidar. This lidar was tall tower validated (see validation information), and then deployed at the ASIT, next to the existing Leosphere Windcube. After a comparison period (see comparison report), the Windcube was relocated to a secondary land based site in Nantucket, MA. Data from both instruments is included in this repository. One deployment of the metocean sensors on the ASIT was made, spanning Nov. 2016 to present. Data from the two cup anemometers (at 26m amsl) and single wind direction vane (at 23m amsl) were combined with additional sensor data of air temperature, pressure, and Relative humidity (at 18m amsl) and ocean temperature and salinity (at 4m bmsl). These additional data were collected by various sensors and were maintained by WHOI or other ASIT users. Commissioning reports for both of the lidar deployments and the metocean sensors are included as part of this repository. See below or the commissioning reports for details of the sensors and sensor orientations, which differed between deployments.’ DATA_ORIGIN = 'Woods Hole Oceanographic Institution, Department of Physical Oceanography' FUNDING_SOURCE = 'The observations used in this study were supported by the Massachusetts Clean Energy Center from 2016 to 2020 and the National Offshore Wind Research and Development Consortium from 2021 to present.
