cf.Bounds.arcsin

Bounds.arcsin(*args, **kwargs)[source]

Take the trigonometric inverse sine of the data element-wise.

Units are ignored in the calculation. The result has units of radians.

The “standard_name” and “long_name” properties are removed from the result.

Added in version 3.2.0.

Parameters:
inplace: bool, optional

If True then do the operation in-place and return None.

Returns:
Bounds or None

The construct with the trigonometric inverse sine of data values. If the operation was in-place then None is returned.
