wind_speed_of_gust_due_to_convection
Unit: m s-1
Unit ref: UVAA
Speed is the magnitude of velocity. Wind is defined as a two-dimensional (horizontal) air velocity vector, with no vertical component. (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. The specification of a physical process by the phrase "due_to" process means that the quantity named is a single term in a list of terms, the maximum of which composes the general quantity named by omitting the phrase.

deployment_latitude
Unit: degree_north

The latitude of deployment of a station or instrument. The term can be used whenever the deployment position of a station or instrument needs to be supplied along with other types of positions. If a data variable has only one latitude coordinate variable, the standard name of latitude should generally be preferred to deployment_latitude, because latitude is recognised by generic software. If the deployment latitude is also the nominal latitude for a discrete geometry (as in Section 9.5 of the CF convention), the deployment latitude should also, or instead, be recorded in a coordinate variable with the standard name of latitude and axis="Y". Latitude is positive northward; its units of "degree_north" (or equivalent) indicate this explicitly.

If the deployment longitude is also the nominal longitude for a discrete geometry (as in Section 9.5 of the CF convention), the deployment longitude should also, or instead, be recorded in a coordinate variable with the standard name of longitude and axis="X". Longitude is positive eastward; its units of "degree_east" (or equivalent) indicate this explicitly.
