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

Text: The MODIS Mosaic of Antarctica (Figure 4) is available from the National
Snow and Ice Data Center (NSIDC, https://nsidc.org/data/moa/). MODIS imagery for the surface
albedo calculations were downloaded from via NASA GSFC (https://modis.gsfc.nasa.gov), and
LANDSAT imagery via the USGS EarthExplorer (http://earthexplorer.usgs.gov). PALSAR data
are available via the Alaska Satellite Facility website (https://vertex.daac.asf.alaska.edu/). The
high-resolution DEM from TanDEM-X is available for use via Pangaea (download link in preparation).
The climate model, firn model, and field observations are available from the corresponding
author on reasonable request<|eot_id|><|start_header_id|>assistant<|end_header_id|>
