gh –Geopotential height (gpm)

3 variants

Height derived from geopotential divided by standard gravity (9.80665 m s-2).

Used on constant pressure levels to diagnose synoptic features (e.g., troughs, ridges, cyclones).
At the surface, it reflects orography (geopotential height of the surface).
A geopotential metre is approximately 2% shorter than a geometric metre.

msl –Mean sea level pressure (Pa)

1 variant

Atmospheric pressure adjusted to mean sea level, reflecting the weight of the air column.

Maps of mean sea level pressure highlight cyclones, anticyclones, and wind strength via contour spacing.
Often expressed in hPa or millibars (1 hPa = 1 mb = 100 Pa).

t –Temperature (K)

3 variants

Air temperature throughout the atmosphere.

Units are kelvin (K); to convert to degrees Celsius (deg C), subtract 273.15.
Available on multiple vertical levels.

`pl 250`	0h-360h	`{"name":"t","level":"pl 250","info":""}`
`pl 500`	0h-360h	`{"name":"t","level":"pl 500","info":""}`
`pl 850`	0h-360h	`{"name":"t","level":"pl 850","info":""}`

ws –Wind speed (m s-1)

2 variants

Magnitude of wind velocity. The dataset determines whether this is the ensemble mean or standard deviation.

Level	Info	Horizon	Selector
`pl 250`		0h-360h	`{"name":"ws","level":"pl 250","info":""}`
`pl 850`		0h-360h	`{"name":"ws","level":"pl 850","info":""}`
