apply magnetic variation to wind data from AVPs

Status: assigned

Reported by: haines Assigned to: haines (accepted)
Priority: major Milestone:
Component: raw2proc Version:
Keywords: Cc:

Verify that u,v component and wind direction are NOT adjusted for magnetic variation at the AVP sites (Hampton, Morgan, and Stones). Then apply the correction from mvar value in proc_avp_ysi_6600_v2.py provided in each config-file for the platform location.

This info is from Tony Whipple.

Wind:

Date, time, speed (m/s), direction (magnetic), compass direction (magnetic), North (m/s), East (m/s), n-samples

See raw2proc page for info on this component.

Verified with Tony and Ryan that data are NOT adjusted for mag var and what was reported for direction, u and v and buoy compass are relative to Magnetic North.

Go ahead when ready to implement using mvar in config-file make adjustment to True North.

Also, noted is an consistent offset in wdir between morgan and stones. This may be a compass calibration issue on the station according to Ryan.
