Validation results ITU-R P.453-14¶
This page contains the validation examples for Recommendation ITU-R P.453-14: TBD.
All test cases were extracted from the ITU Validation examples file (rev 5.1).
Function map_wet_term_radio_refractivity¶
The table below contains the results of testing function map_wet_term_radio_refractivity.
The test cases were extracted from spreadsheet ITURP453-14_Nwet.csv from the
ITU Validation examples file (rev 5.1).
In addition to the input-arguments, expected result (ITU Validation), and
ITU-Rpy computed result (ITUR-py Result), the absolute and relative errors
are shown. Each test case is color-coded depending on the magnitude of the
errors (green = pass, errors are negligible, red = fail, relative error is
above 0.01%).
In addition, the code snippet below shows an example of how to generate the first row of the results in the table:
import itur
# Define input attributes
lat = 3.133 # (°N)
lon = 101.7 # (°E)
p = 50.0 # (%)
# Make call to test-function map_wet_term_radio_refractivity
itur_val = itur.models.itu453.map_wet_term_radio_refractivity(lat=lat, lon=lon, p=p)
# Compute error with respect to value in ITU example file
ITU_example_val = 128.1408003 # nan
error = ITU_example_val - itur_val.value
error_rel = error / ITU_example_val * 100 # (%)
