Data Status: These profiles are directly from the field and are posted as PRELIMINARY.
Data Policy: We request that a proper acknowledgment to the "NOAA Earth System Research Laboratory Chemical Sciences Division" accompany the use of this data in any publications and presentations. If the use of this data in a publication constitutes a major or reasonably significant aspect of an article, co-authorship by an ESRL scientist is appropriate; please discuss any such planned use with the contact scientists. We welcome collaborations and will lend our scientific expertise in interpretation and evaluation of the data.

Data format : Netcdf
The file has the following form:
version: 100
The following variables have the dimension of time
year
yDay (decimal day of year)
latitude, longitude (degrees) average value for the entire vertical profile
The following variables have the dimension of height
height (m) above ground level
The following variables have the dimension of height X time
speed: (m/s) horizontal wind speed
direction: (deg) horizontal wind direction (0 means winds are from the north)
dSpeed: (m/s) standard deviation of the mean of the wind speed estimate
dDirection: (deg) standard deviation of the mean of the wind direction estimate
count: # of radial windspeed estimates in the fit
residVar:variance of the radial wind speed data after the fit has been removed (m^2/s^2)
avgR: average horizontal radius (from the lidar) of the points in the fit
