Urban cooling calibration

Science, Research & Data

Hello

I am learning the calibration process and I wonder if I need the stations data and the LST or if I can calibrate the model with one of them because I only have LST.

Best,

Isa

Hello @Isabel , I’m sorry about the delay in getting back to you on this.

Could you provide some additional information? What calibration process are you running?

Thanks,
James

I am working with the Urban Cooling Model, and I obtained the map results, but I am struggling with the calibration.

I’m currently trying to calibrate the InVEST Urban Cooling Model using the invest-ucm-calibration tool with Landsat-derived daytime LST for the city of Coronel, Chile.

I’ve followed the available documentation and attempted setup in PyCharm (venv) and Anaconda Prompt (Conda environment). I’m experiencing issues that prevent the model from running — the CLI executes but shows only a GDAL warning, and no further output (no sampling, no running, no errors).

My inputs are in the “data” folder:
LST_Resample.tif — observed LST LULC_Coronel2023.tif — land cover raster
EVT_JANResam.tif — reference ET₀ raster BiophysicalTable_FOR_UCM.csv — biophysical table
Config file: “config/calibration_config.yaml”

I followed these steps:
In PyCharm:

  1. Installed Python 3.10
  2. Created a “.venv” environment
  3. Installed GDAL and “invest-ucm-calibration” via pip
  4. Created a “run_calibration.py” script
  5. Faced ModuleNotFoundError: No module named 'ucm_calibration'

In Conda:

  1. Created ucm_calibration environment
  2. Installed gdal, numpy, scipy via conda-forge
  3. Cloned repo from GitHub
  4. Moved all input files into invest-ucm-calibration/data/
  5. Used the recommended CLI run command

However, the model does not run :frowning: . There is no “cli.py” anymore — instead there is “cli/main.py”, but documentation still references the older structure. Even when running “main.py” manually or with “-m”, the tool does not seem to enter the calibration flow.

I have the following questions:

  1. What is the current expected structure of “calibration_config.yaml”?
  2. Has the CLI interface changed? Should we still be using “main.py run config.yaml”?
  3. Is there a working example config and input folder to test against?

Thanks in advance :slight_smile:

@Emma , might you be of any help here to Isa? Thanks.
