SzaRasterizer for H5 files

Methods

get_data()	Get a raster of source values corresponding to the high-res grid (the file_paths input grid * s_enhance * t_enhance).
get_distance_upper_bound()	Maximum distance (float) to map high-resolution data from source_file to the low-resolution file_paths input.

Attributes

cache_dir
cache_file	Get cache file name
chunks
coords	Get coords dictionary for initializing xr.Dataset.
data	Get a raster of source values corresponding to the high-resolution grid (the file_paths input grid * s_enhance * t_enhance).
distance_upper_bound
feature
file_paths
hr_lat_lon	Lat lon grid for data in format (spatial_1, spatial_2, 2) Lat/Lon array with same ordering in last dimension.
hr_shape	Get the high-resolution spatiotemporal shape
hr_time_index	Get the full time index for aggregated source data
input_handler_kwargs
input_handler_name
lr_shape	Get the low-resolution spatiotemporal shape
max_workers
nn	Get the nearest neighbor indices.
s_enhance
source_data	Get the 1D array of sza data from the source_file_h5
source_file
source_handler	Get the Loader object that handles the exogenous data file.
source_lat_lon	Get the 2D array (n, 2) of lat, lon data from the source_file_h5
t_enhance
tree	Get the KDTree built on the target lat lon data from the file_paths input with s_enhance
verbose

property source_data

Get the 1D array of sza data from the source_file_h5

get_data()

Get a raster of source values corresponding to the high-res grid (the file_paths input grid * s_enhance * t_enhance). The shape is (lats, lons, temporal)

property cache_file

Get cache file name

Returns:

cache_fp (str) – Name of cache file. This is a netcdf file which will be saved with Cacher and loaded with Loader

property coords

Get coords dictionary for initializing xr.Dataset.

property data

Get a raster of source values corresponding to the high-resolution grid (the file_paths input grid * s_enhance * t_enhance). The shape is (lats, lons, temporal, 1)

get_distance_upper_bound()

Maximum distance (float) to map high-resolution data from source_file to the low-resolution file_paths input.

property hr_lat_lon

Lat lon grid for data in format (spatial_1, spatial_2, 2) Lat/Lon array with same ordering in last dimension. This corresponds to the enhanced meta data from the file_paths input * s_enhance.

Returns:

ndarray

property hr_shape

Get the high-resolution spatiotemporal shape

property hr_time_index

Get the full time index for aggregated source data

property lr_shape

Get the low-resolution spatiotemporal shape

property nn

Get the nearest neighbor indices. This uses a single neighbor by default

property source_handler

Get the Loader object that handles the exogenous data file.

property source_lat_lon

Get the 2D array (n, 2) of lat, lon data from the source_file_h5

property tree

Get the KDTree built on the target lat lon data from the file_paths input with s_enhance
