rainfallqc.utils.spatial_utils.compute_spatial_mean_xr(data, var_name)

Get the value at the nearest ETCCDI grid cell to the gauge coordinates.

Parameters:

• data (Dataset) – Data with variable to compute mean from. Should have lat/lon and time (as axis 0)

• var_name (str) – Variable to make mean value of

Return type:

Dataset

Returns:

:

data

Data with spatial mean

rainfallqc.utils.spatial_utils.haversine(lon1, lat1, lon2, lat2)

Great circle distance (km) between two points on Earth.

Parameters:

• lon1 (DataArray) – Longitude of point 1

• lat1 (DataArray) – Latitude of point 1

• lon2 (ndarray | float) – Longitude of point 2

• lat2 (ndarray | float) – Latitude of point 2

Return type:

float

Returns:

:

distancefloat

Distance between the two points in km
