Monthly total freeboard and snow depth over Arctic sea ice from AMSR-E&2 and AVHRR measurements (2003-2020)

<p><strong>[Data description]</strong></p> <p>Monthly total freeboard (Ft),&nbsp;snow depth (hs), and snow depth uncertainty over Arctic sea ice data for January-February-March months of the 2003-2020 period produced by Lee and Shi et al. (2021, manuscript under review) are provided.</p> <p>Both variables are derived from satellite passive infrared and microwave measurements: Total freeboard was obtained from AMSR-E&amp;2 measurements and snow depth was estimated from the AMSR and AVHRR measurements.</p> <p>The uploaded file titled &quot;monthly averaged total freeboard and snow depth (JFM 2003-2020).zip&quot; contains two directories: one for total freeboard and the other for snow depth. Naming convention is &quot;variable_yyyymm.bin&quot; and data format is 32-bit floating point array in shape of 304 x 448 (25 km polar stereographic grid).</p> <p>Here we provide an example Python code to read monthly snow depth of January 2003 using numpy.<br> &nbsp; import numpy as np<br> &nbsp; hs = np.fromfile(&#39;hs_200301.bin&#39;, dtype=np.float32).reshape(448,304)</p> <p>Geocoordinate tools for the 25 km polar stereographic grid are available at NSIDC website (https://nsidc.org/data/polar-stereo/tools_geo_pixel.html)<br> &nbsp;<br> <strong>[Abbreviations]</strong></p> <p>AMSR: Advanced Microwave Scanning Radiometer<br> AVHRR: Advanced Very High Resolution Radiometer<br> NSIDC: National Snow and Ice Data Center</p>
