CloudnetPy-QC CI PyPI version

Software for evaluating quality of ACTRIS-Cloudnet data products.

Installation

$ pip3 install cloudnetpy-qc

Usage

import json
from cloudnetpy_qc import quality
report = quality.run_tests('cloudnet-file.nc')
json_object = json.dumps(report.to_dict(), indent=2)
print(json_object)

Format of the report

  • timestamp: UTC timestamp of the test
  • qcVersion: cloudnetpy-qc version
  • tests: Test[]

Test

  • testId: Unique name of the test
  • exceptions: Exception[]

Exception

  • message: Free-form message about the exception
  • result: "info", "error" or "warning"

Example:

{
  "timestamp": "2022-10-13T07:00:26.906815Z",
  "qcVersion": "1.1.2",
  "tests": [
    {
      "testId": "TestUnits",
      "exceptions": []
    },
    {
      "testId": "TestInstrumentPid",
      "exceptions": [
        {
          "message": "Instrument PID is missing.",
          "result": "warning"
        }
      ]
    },
    {
      "testId": "TestTimeVector",
      "exceptions": []
    },
    {
      "testId": "TestVariableNames",
      "exceptions": []
    },
    {
