The campaign was designed to observe key atmospheric parameters at a land based site in the proximity of the Massachusetts and Rhode Island Wind Energy Areas for one year. This is part of a longer term effort to collect atmospheric and oceanic data at an existing offshore platform in the vicinity, which can be found here {HYPERLINK: https://darchive.mblwhoilibrary.org/handle/1912/27014}. The campaign supported the purchase and installation of a LIDAR wind profiler at the Nantucket Test Site (NTS). This instrument was installed and operated by WHOI and validated by UL-AWS Truepower following a MetOcean Measurement Plan created by UL-AWST, WHOI, and NOWRDC. The LIDAR was installed at the NTS in November 2021 and operated continuously, as possible, through the end of 2024. The lidar was removed for service and tall tower validation from 4-24-2023 to 10-23-2023.' DESCRIPTION = 'A LEOSPHERE WINDCUBE v2 was acquired from NRG Systems and deployed at the NTS after a previous deployment at WHOI's offshore Air Sea Interaction Tower (ASIT). The WIND-CUBE 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 ground level in an open area and leveled following LEOSPHERE standards. A commissioning report for the lidar deployment are included as part of this repository.’ DATA_ORIGIN = 'Woods Hole Oceanographic Institution, Department of Physical Oceanography' FUNDING_SOURCE = 'The observations used in this study were supported by the National Offshore Wind Research and Development Consortium.
