EIDA Consistency

eida-consistency is a tool and library to check the consistency between EIDA availability and dataselect services.

It verifies that data advertised as available (via the availability service) can actually be downloaded (via the dataselect service).

Installation

pip install eida-consistency

Or using uv / poetry:

uv add eida-consistency

Quick Start as a Library

To use the tool programmatically, you can import the core checker or the full runner.

Check a Single Candidate

from eida_consistency.core.checker import check_candidate
from datetime import datetime

# Define a candidate (network, station, channel, starttime)
candidate = {
    "network": "GR",
    "station": "ATH",
    "channel": "BHZ",
    "starttime": "2023-01-01T00:00:00",
    "endtime": "2023-01-02T00:00:00"
}

# Run the check
results, stats = check_candidate(
    base_url="http://node.eida.eu/ fdsnws", # Replace with actual node URL
    candidate=candidate,
    epochs=5,
    duration=600
)

for res in results:
    url, available, start, end, loc, span = res
    print(f"Time: {start} -> Available: {available}")

Run a Full Consistency Check

from eida_consistency.runner import run_consistency_check

# Run check for a specific node
report_path = run_consistency_check(
    node="NOA",
    epochs=10,
    duration=600
)

print(f"Report generated at: {report_path}")
