Global River Ice Dataset

<p>This dataset is public for a manuscript under review. The dataset consists of one csv file containing estimated river ice (length) fraction based on images from USGS Landsat satellite missions.&nbsp;</p> <p><strong>Documentation for the Global River Ice Dataset</strong></p> <p>This&nbsp;csv file contains 840,187 records (rows) of river ice length fraction derived from Landsat satellite images.</p> <p>For each river ice fraction, we have the following associated properties:<br> 1.&nbsp;&nbsp; &nbsp;date: The date on which the image was captured (format: YYYY-MM-DD; data type: string)<br> 2.&nbsp;&nbsp; &nbsp;river_ice_fraction: The length fraction of ice cover (format: decimal number;&nbsp;data type: float; range: [0, 1])<br> 3.&nbsp;&nbsp; &nbsp;cloud_fraction: The length fraction of cloud cover (format: decimal number;&nbsp;data type: float; range: [0, 1])<br> 4.&nbsp; &nbsp; topo_shadow: Average topographic shadow along river centerline (format: decimal number;&nbsp;data type: float; range: [0, 1] with 0 meaning fully in shadow)<br> 5.&nbsp;&nbsp; &nbsp;LANDSAT_SCENE_ID: The unique Landsat TOA image identifier (data type: string)<br> 6.&nbsp;&nbsp; &nbsp;PATH: The path of the Landsat image (under <a href="https://landsat.gsfc.nasa.gov/the-worldwide-reference-system/">WRS-2</a>), roughly related to the longitudinal position of the image (data type: integer)<br> 7.&nbsp;&nbsp; &nbsp;ROW: The row of the Landsat image (under <a href="https://landsat.gsfc.nasa.gov/the-worldwide-reference-system/">WRS-2</a>), roughly related to the latitudinal&nbsp;position of the image (data type: integer)<br> 8.&nbsp;&nbsp; &nbsp;N_river_pixel: Number of total centerline points intersecting with the Landsat image (data type: integer)<br> 9.&nbsp;&nbsp; &nbsp;N_clear_river_pixel: Number of centerline points free from cloud or cloud shadow cover that intersected&nbsp;with the Landsat image (data type: integer)</p> <p>The dataset used for analysis is a subset (No. of records: 407,542)&nbsp;of this dataset with implementing the following three constraints:</p> <ol> <li>&nbsp;<span class="math-tex">\(N\_clear\_river\_pixel ≥ 333\)</span></li> <li><span class="math-tex">\(topo\_shadow ≥ 0.95\)</span></li> <li><span class="math-tex">\(cloud\_fraction ≤0.25\)</span></li> </ol>
