资源简介:

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