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 analyzed in this study are publically available. Satellite observations used for
 calculating GPP can be obtained from the Numerical Terradynamic Simultion Group data portal
 (http://www.ntsg.umt.edu/data). All data for estimating NBP are available through the Global
Carbon Project53, with errors estimated from Li et al 80 579 . Simulated terrestrial carbon cycle data
 were obtained for ESMs from the CMIP5 archive accessed through the Earth System Grid
Federation data portal (http://esgf.llnl.gov) and from DGVMs from the TRENDY archive16 581 . Land
 surface temperature data used for calculating temperature sensitivity were obtained from three
 public available sources- Climate Research Unit
(https://crudata.uea.ac.uk/cru/data/temperature/), NASA Goddard Institute for Space Studies
 (http://data.giss.nasa.gov/gistemp/), and NOAA (https://www.ncdc.noaa.gov/data-
 access/marineocean-data/noaa-global-surface-temperature-noaaglobaltemp).<|eot_id|><|start_header_id|>assistant<|end_header_id|>
