The Windcube data is compressed via 7-zip:

"sta" files are 10 minute averaged data.
"rtd" files are ~1 second data.
"gyro" files are buoy movement data.

7z is the new archive format, providing high compression ratio.

The main features of 7z format:
Open architecture
High compression ratio
Strong AES-256 encryption
Ability of using any compression, conversion or encryption method
Supporting files with sizes up to 16000000000 GB
Unicode file names
Solid compressing
Archive headers compressing

7z has open architecture, so it can support any new compression methods.

**Data Quality**

Additional meta data to follow.

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.
