radtraq.proc.extract_profile_at_lat_lon(obj, desired_lat, desired_lon, append_obj=None, azimuth_name='azimuth', range_name='range', elevation_name='elevation', azimuth_range=None, ground_dist_range=200, variables=None, lat_name_in_obj='lat', lon_name_in_obj='lon')[source]

Function for extracting vertical profile over a location defined by latitude and longitude from a PPI scan

Parameters:

  • obj (Xarray.Dataset) – Xarray object with all the data

  • desired_lat (float) – Latitude of desired profile in same units as latitued in obj

  • desired_lon (float) – Longitude of desired profile in same units as longitude in obj

  • append_obj (Xarray.Dataset) – Xarray Dataset to return with new profile appened.

  • azimuth_name (str) – Name of azimuth variable in obj

  • range_name (str) – Name of range variable in obj

  • elevation_name (str) – Name of elevation variable in obj

  • azimuth_range (float or None) – Range to use for tollerance in selecting azimuth to extract profile. If set to None will use the mode of azimuth differences. Assumed to be in degrees.

  • ground_dist_range (float) – Distance range window size allowed to extract profile. If the profile location is off from lat/lon location by more than this distance, will not extract a profile and will return None.

  • variables (str, list, None) – List of variables to extract profile

  • lat_name_in_obj (str) – Name of latitude varible in object

  • lon_name_in_obj (str) – Name of longitude varible in object

Returns:

obj – Xarray Dataset with profile extracted at desired latitued and longitude location, and new coordinate variable height added.

Return type:

Xarray.Dataset
