Using pyfwg for direct morphing with morph_epw_global and morph_epw_europe (v4 Update)

This notebook demonstrates the simplest and most direct way to use the pyfwg library: the morph_epw_global and morph_epw_europe functions.

These functions are designed as one-shot tools that provide full access to all of the Future Weather Generator’s parameters without requiring the user to manage the multi-step MorphingWorkflow class. It handles parameter validation, temporary file management, and final file placement in a single call.

Note: pyfwg now fully supports FutureWeatherGenerator v4.0.x (Global) and v2.0.x (Europe), which include a new keyword-based CLI, support for string-based parameter options (like 'AVG4P' for interpolation), and additional output formats (like 'MET' or 'CSV').

Understanding the Parameters

The morph_epw_global and morph_epw_europe functions are powerful because these exposes all of the underlying tool’s options. Here is a complete reference for all their arguments.

Core Parameters

  • epw_paths (Union[str, List[str]]): Required. The path to a single EPW file (as a string) or a list of paths to multiple EPW files.

  • fwg_jar_path (str): Required. The absolute or relative path to the Future Weather Generator .jar file (e.g., FutureWeatherGenerator_v4.0.2.jar).

Workflow Control Parameters

  • output_dir (str, default: './morphed_epws'): The directory where the final morphed files will be saved.

  • delete_temp_files (bool, default: True): If True, the temporary folders are deleted after processing. Set to False for debugging.

  • temp_base_dir (str, default: './morphing_temp_results'): The base directory where temporary folders will be created.

  • fwg_show_tool_output (bool, default: False): If True, prints the FWG tool’s console output in real-time. Highly recommended for monitoring progress.

  • fwg_params (Optional[Dict], default: None): A dictionary for providing a base set of FWG parameters. Any explicit fwg_ argument will override the values in this dictionary.

Future Weather Generator Tool Parameters

These arguments correspond directly to the options in the FWG command-line tool.

  • fwg_gcms (Optional[List[str]], default: None): Only valid for ``morph_epw_global``. A list of GCMs to use. If None, the full default list is used to create an ensemble.

  • fwg_rcm_pairs (Optional[List[str]], default: None): Only valid for ``morph_epw_europe``. List of GCM-RCM pairs to use. If None, the tool’s default list is used.

  • fwg_create_ensemble (bool, default: True): If True, creates an ensemble from the selected GCMs.

  • fwg_winter_sd_shift (float, default: 0.0): Temperature’s standard deviation shift for the winter peak month. Range: -2.0 to 2.0.

  • fwg_summer_sd_shift (float, default: 0.0): Temperature’s standard deviation shift for the summer peak month. Range: -2.0 to 2.0.

  • fwg_month_transition_hours (int, default: 72): Number of hours to smooth the transition between months. Range: 0 to 336.

  • fwg_use_multithreading (bool, default: True): If True, performs computations in multithread.

  • fwg_interpolation_method_id (Union[int, str], default: 0): Selects the grid method. Legacy options: 0 (IDW), 1 (AVG4P), 2 (NP). V4/Europe v2 options: you can use strings: 'IDW', 'BI', 'AVG4P', 'NP'.

  • fwg_limit_variables (bool, default: True): If True, bounds each generated variable to its physical limits.

  • fwg_solar_hour_adjustment (Union[int, str], default: 1): Option for solar hour adjustment. Legacy options: 0, 1, 2. V4 options: 'None', 'By_Month', 'By_Day'.

  • fwg_diffuse_irradiation_model (Union[int, str], default: 1): Option for diffuse solar irradiation model. Legacy options: 0, 1, 2. V4 options: 'Ridley_Boland_Lauret_2010', 'Engerer_2015', 'Paulescu_Blaga_2019'.

  • fwg_add_uhi (bool, default: True): Option to pre-process the Urban Heat Island (UHI) effect.

  • fwg_epw_original_lcz (int, default: 14): The Local Climate Zone (LCZ) of the original EPW. Range: 1 to 17.

  • fwg_target_uhi_lcz (int, default: 1): The target LCZ of the generated EPW. Range: 1 to 17.

  • fwg_output_type (str, default: 'EPW'): New in V4/Europe v2. Format of output files: 'EPW', 'SPAIN_MET', or 'PORTUGAL_CSV'.

  • fwg_version (Optional[str], default: None): Force a specific CLI version (e.g., '4'). If None, pyfwg auto-detects from the JAR filename.

Using morph_epw_global

Step 1: Imports and Setup

First, we’ll import the necessary function and set up our file paths.

Important: You must change the jar_path variable to the correct location of your Future Weather Generator .jar file. pyfwg will automatically detect the version (v3 or v4) and adapt the CLI command accordingly.

[1]:

import os
from pyfwg import get_fwg_parameters_info, morph_epw_global, get_available_lczs, check_lcz_availability, DEFAULT_GLOBAL_GCMS

# --- Configuration ---
# Define the path to the EPW file to be processed. You can also define a list of paths to process multiple EPW files.
epw_file = 'epws/w_pattern/sevilla_uhi-type-1.epw'

# !!! IMPORTANT: You MUST change this path to the correct location on your PC !!!
jar_path = r"D:\OneDrive - Universidad de Cádiz (uca.es)\Programas\FutureWeatherGenerator_v4.0.2.jar"

Exploring FWG Parameters

Before configuring the workflow, you might want to know which parameters are available and what values they accept. This is especially useful for the new string-based options in V4.

You can use the get_fwg_parameters_info utility to get a detailed list of all parameters.

[2]:

import json
# Get the info and print it nicely
info = get_fwg_parameters_info()
print(json.dumps(info, indent=4))

Step 2: Pre-flight Checks (Recommended). Check Available LCZs.

Before running a long morphing process, it’s a good practice to validate your parameters. pyfwg provides utility functions to help with this.

The fwg_epw_original_lcz and fwg_target_uhi_lcz parameters depend on which Local Climate Zones are available for a specific weather file location. We can find this out using get_available_lczs.

[3]:

available_zones = get_available_lczs(
    epw_paths=epw_file,
    fwg_jar_path=jar_path,
    # In java_class_path_prefix, use 'futureweathergenerator' for the global scope FWG tool, otherwise 'futureweathergenerator_europe'
    java_class_path_prefix='futureweathergenerator',
    show_tool_output=False,
)

[4]:

# Print the results in a user-friendly format
for filename, lcz_list in available_zones.items():
    print(f"\nAvailable LCZs for: {filename}")
    if lcz_list:
        print(f"  {lcz_list}")
    else:
        print("  Could not be determined.")


Available LCZs for: sevilla_uhi-type-1.epw
  [2, 3, 6, 8, 9, 11, 12, 13, 14, 16]

Step 3: Run the Morphing Process

Now, we can call the morph_epw_global function. We will override a few of the default parameters to demonstrate how to customize the process. To speed up the process, let’s use just one GCM. If you don’t know which are these, you can import the list containing the default models:

[5]:

from pyfwg import get_fwg_parameters_info, DEFAULT_GLOBAL_GCMS
print(DEFAULT_GLOBAL_GCMS)

{'GISS_E2_1_H', 'CNRM_CM6_1', 'MIROC6', 'IPSL_CM6A_LR', 'CMCC_ESM2', 'EC_Earth3_Veg', 'EC_Earth3_Veg_LR', 'BCC_CSM2_MR', 'CanESM5_CanOE', 'FGOALS_g3', 'GISS_E2_2_G', 'CanESM5_1', 'GFDL_ESM4', 'CNRM_CM6_1_HR', 'MRI_ESM2_0', 'MIROC_ES2H', 'EC_Earth3', 'MIROC_ES2L', 'CanESM5', 'UKESM1_0_LL', 'GISS_E2_1_G', 'CAS_ESM2_0', 'CNRM_ESM2_1'}

So let’s use for instance “CanESM5”. Note that in V4, we can use descriptive strings for parameters like fwg_interpolation_method_id.

[6]:

# The validation of parameters is executed automatically inside the function.
created_files_custom = morph_epw_global(
    epw_paths=epw_file,
    fwg_jar_path=jar_path,
    output_dir='./custom_output_global',
    fwg_show_tool_output=True,      # See the tool's progress in real-time
    fwg_gcms=['CanESM5'],           # Use only one specific GCM for speed
    fwg_interpolation_method_id='AVG4P',  # V4 feature: Use string names!
    fwg_epw_original_lcz=2,         # Use a validated LCZ from the check above
    fwg_target_uhi_lcz=3,          # Use a validated LCZ from the check above
    fwg_version='4'                 # Explicitly force V4 syntax
)

Expected Output

When you run the code above with V4, you should see:

  1. A detailed printout of the keyword-based command being executed (e.g., -epw=... -models=CanESM5).

  2. The real-time console output from the Future Weather Generator tool.

  3. A final message listing all the created files in the ./custom_output_global directory.

Let’s delete the files we just generated.

import shutil
if os.path.exists('custom_output_global'):
    shutil.rmtree('custom_output_global')

Using morph_epw_europe

FYI: the usage of morph_epw_europe is very similar to the global version. The only differences are:

  • Instead of argument fwg_gcms, you need to use fwg_rcm_pairs.

  • Instead of variable DEFAULT_GLOBAL_GCMS, the available models are in variable DEFAULT_EUROPE_RCMS.

  • Future scenarios are RCP instead of SSP.

  • You have to remember using the jar_path to the FutureWeatherGenerator_Europe_vx.x.x.jar file.

Step 1: Imports and Setup

Important: Change the jar_path variable to the correct location of your European version JAR (v1.x for legacy or v2.x for the update).

[9]:

from pyfwg import get_fwg_parameters_info, morph_epw_europe

# !!! IMPORTANT: You MUST change this path to the correct location on your PC !!!
jar_path_europe = r"D:\OneDrive - Universidad de Cádiz (uca.es)\Programas\FutureWeatherGenerator_Europe_v2.0.2.jar"

Step 2: Run the Morphing Process

Now, we can call the morph_epw_europe function. In Europe v2, we can also specify a different output format like 'MET'.

[10]:

from pyfwg import get_fwg_parameters_info, DEFAULT_EUROPE_RCMS

created_files_custom = morph_epw_europe(
    epw_paths=epw_file,
    fwg_jar_path=jar_path_europe,
    output_dir='./custom_output_europe',
    fwg_show_tool_output=True,
    fwg_rcm_pairs=[list(DEFAULT_EUROPE_RCMS)[0]],  # Use the first pair for speed
    fwg_interpolation_method_id='NP',              # Nearest Point
    fwg_epw_original_lcz=2,
    fwg_target_uhi_lcz=3,
    fwg_output_type='SPAIN_MET'                         # Output formatted as MET files
)
