**Overview** This dataset compiles results from different model-based hindcasts and instruments that measure environmental variables at the location of the associated lidar buoys. This dataset complements the lidar buoy measurements by providing longer time histories of selected environmental parameters. The data were extracted from the closest grid point to the average lidar buoy position. The data were obtained from the public domain and references to the originators/owners are provided under each instrument.

**Overview** The purpose of this dataset is to provide preliminary filtered, averaged lidar data and standardize the data format of various datastreams from the buoy into NetCDF. **Data Quality** Standard filtering thresholds on the averaged data were applied and several data format issues of the raw data were streamlined to create a standardized NetCDF format data. **Uncertainty** The uncertainty of lidar data has not been analyzed, but they are not expected to deviate from instrument technical specifications.

**Overview** The purpose of the dataset is to provide preliminary filtered, averaged buoy data and standardize the data format of various data streams from the buoy into NetCDF. The attached Lidar Buoy Data Dictionary provides further details on the various instruments mounted on the buoys, parameters measured by each instrument, and the frequency of data collection. **Data Details** Surface meteorology instrument directions are not correct for majority of the deployment because faulty inertial measurement unit (IMU) data was used for heading calculations. These directions will be reprocessed using the high frequency GX5-45 IMU data at the end of the campaign and the directions will be updated. **Data Quality** Standard filtering thresholds on the averaged data were applied and several data format issues of the raw data were streamlined to create a standardized NetCDF format data. **Uncertainty** The uncertainty of data has not been analyzed, but it is not expected to deviate from instrument technical specifications.

PNNL recommends adding 180 degrees to the lidar wind directions at Morro Bay, as there is a directional issue associated with GPS cables being swapped on the buoy during buoy commissioning. The 180 degrees offset is going to be very close to our final post-processed data, that will be uploaded at the end of the campaign in September or November 2021.

**Overview** This is the data collected during the validation period. The buoy is scheduled to be deployed near Martha's Vinyard in mid-January 2020. Data collected from buoy instruments are contained in two files labeled “primary” and secondary.” Header information for these files can be found in the respective tabs in the Excel spreadsheet under Attachments. **Data Details** Add information about buoy data files here.

Beacon Wind LiDAR Buoy - Realtime Data. This dataset contains observations to support the development of the Beacon Wind Offshore Wind Project and to further understanding of metocean conditions off the coast of Massachusetts. The Beacon Wind Site Assessment Plan approved by the Bureau of Ocean Energy Management can be found at Beacon Wind | Bureau of Ocean Energy Management (boem.gov) Data is collected from one Floating LiDAR Buoy, two Wave/Met Buoys, and two Current Meter Moorings. The dataset includes measurements of sea temperature, current speed, current direction, waves, air temperature, atmospheric pressure, relative humidity, wind speed, and wind direction.

The National Data Buoy Center (NDBC) maintains a database of near realtime observational recordings for buoys. This database contains not only NDBC buoys but also non-NDBC buoys. These buoys record information such as wind speed and direction, wave heights, surface atmospheric pressure, air temperature, water temperature, and visibility.
