varunayan.search_and_desc.search_and_desc_functions.describe_variables(variable_names: List[str], dataset_type: str) → Dict[str, str]

Get descriptions for specific variables

Parameters:

• variable_names (list) – List of variable names to describe

• dataset_type (str) – Dataset type to search (“single”, “pressure”, “all”, or any other registered dataset)

List all available variable names for a dataset type.

Parameters:

dataset_type – Dataset type (“single”, “pressure”, or “all”)

Returns:

List of variable names

Get list of available pressure levels for ERA5 pressure level data.

Returns:

List of pressure level strings (in hPa)

varunayan.search_and_desc.search_and_desc_functions.get_variable_info(variable_name: str, dataset_type: str = 'all') → Dict[str, Any] | None

Get detailed information about a specific variable.

Parameters:
