You are an expert at identifying data availability statements in scientific text. A data availability statement describes where research data can be found or how it can be accessed.<|eot_id|><|start_header_id|>user<|end_header_id|>

Determine if the following text contains a data availability statement. Answer with 'yes' or 'no'.

Text: All data used in this work are publically available. Level 2 Principle Component Analysis 451 (PCA) SO2 and Standard Product (SP) version 2.1 NO2 vertical column density (VCD) data from 452 the Ozone Monitoring Instrument (OMI), used to identify emission source locations and derive 453 the SO2 emissions inventory, are available from the Goddard Earth Science and Information Service Center (http://disc.sci.gsfc.nasa.gov/Aura/data-holdings/OMI) 31 454 . Wind reanalysis data from ECMWF ERA interim realaysis14 455 was downloaded from 456 http://apps.ecmwf.int/datasets/data/interim-full-daily/. HTAP-EDGAR v2 emissions data16 457 were downloaded from http://edgar.jrc.ec.europa.eu/htap_v2/index.php?SECURE=123, EDGAR v4.2 emissions data18 458 459 were downloaded from http://edgar.jrc.ec.europa.eu/overview.php?v=42, MACCity emissions data17 460 were downloaded from http://accent.aero.jussieu.fr/MACC_metadata.php, and ODIAC emissions data23 461 were downloaded from 462 http://db.cger.nies.go.jp/dataset/ODIAC/emission_dataset.html.
