(Vertical motion in the atmosphere has the standard name upward air velocity.) The wind speed is the magnitude of the wind velocity. A gust is a sudden brief period of high wind speed. In an observed timeseries of wind speed,  the gust wind speed can be indicated by a cell methods of maximum for the time-interval. In an atmospheric model which has a parametrised calculation of gustiness,  the gust wind speed may be separately diagnosed from the wind speed. Lot 1 uses fx  - WMO abbrev."

 201,"ozone, CH4, CO, HCOCH, NO2",atmospheric,surface; upper-air,solar azimuth angle,degrees,Solar azimuth angle is the horizontal angle between the line of sight to the sun and a reference direction which is often due north. The angle is measured clockwise.

+203, wind, atmospheric, surface; upper-air,wind_run, m, The wind run represents the cumulative horizontal distance traveled by air parcels over the aggregation interval. It is computed as the time integrated wind speed and provides a measure of the total wind passage over a given period.
+204, wind, atmospheric, surface; upper-air, average_wind_power_density, W m-2, Wind power density quantifies the kinetic energy flux available in the wind per unit area and is derived from the cube of the horizontal wind speed assuming a constant air density.
+205, wind, atmospheric, surface; upper-air, wind_stress, N m-2, Wind stress represents the dynamic pressure exerted by the wind on a surface and is computed as a function of air density and the squared mean wind speed.
