    <description descriptionType="Abstract">&lt;p&gt;This data set contains Arctic sea ice thicknesses derived from L-band passive microwave brightness temperatures. For this purpose, brightness temperatures at 40&amp;deg; incidence angle from the SMOS (Soil Moisture and Ocean Salinity) and SMAP (Soil Moisture Active Passive) satellites were combined to a homogenised data set (see also related data sets). Sea ice thicknesses were then derived using the algorithm described in Tian-Kunze et al. (2014).&lt;/p&gt;

&lt;p&gt;Data are generally produced for the freeze-up period from 15 October to 15 April. This data set contains data from on 1 April 2015 (first available SMAP data) to 15 April 2015 and for the winter seasons 2015/16 to 2017/18.&lt;/p&gt;

&lt;p&gt;A detailed description of the data set can be found Schmitt and Kaleschke (2018) and in the document &lt;em&gt;1_Documentation_Combined_SIT.pdf&lt;/em&gt;.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Please note&lt;/strong&gt;: Sea ice thicknesses from L-band are most suitable for thin ice and reach saturation for thicker sea ice (above 0.5 m - 1 m, depending on ice salinity and temperature). Thickness values with a saturation ratio of 100 % should be discarded (depending on the application)!&lt;/p&gt;

&lt;p&gt;Version 1.0 of this data set is based on SMOS version v620 and SMAP version 3 data.&lt;/p&gt;

&lt;p&gt;The files contain the following data fields:&lt;br&gt;
&lt;strong&gt;sea_ice_thickness&lt;/strong&gt; - sea ice thickness with post-processing to account for the thickness distribution&lt;br&gt;
&lt;strong&gt;plane_layer_thickness&lt;/strong&gt; - sea ice thickness using the plane layer assumption&lt;br&gt;
&lt;strong&gt;thickness_uncertainty_upper&lt;/strong&gt; - upper limit of the sea ice thickness uncertainty interval&lt;br&gt;
&lt;strong&gt;thickness_uncertainty_lower&lt;/strong&gt; - lower limit of the sea ice thickness uncertainty interval&lt;br&gt;
&lt;strong&gt;saturation_ratio&lt;/strong&gt; - ratio of plane layer thickness and maximum retrievable thickness (%)&lt;br&gt;
&lt;strong&gt;TB_intensity&lt;/strong&gt; - brightness temperature intensity combined from SMOS and SMAP at 40&amp;deg; incidence angle&lt;/p&gt;

&lt;p&gt;The grid coordinates are provided as a separate file &lt;em&gt;Latlon_e12.5.nc&lt;/em&gt;&lt;/p&gt;</description>
