Island inventory of peak elevation and area for SFTH retrieval over the Yellow and Bohai Seas
收藏资源简介:
This dataset provides island coordinates, areas, and peak elevations used as height references for sea fog top height retrieval. Islands in the Yellow and Bohai Seas offer natural geometric constraints: when fog-top height exceeds island peak elevation, the peak tends to be submerged in imagery; when fog-top height is lower, the peak remains visible and terrain–fog interactions may produce local holes/contrasts.Screening criteria (MODIS 250 m): area > 0.25 km² (≥4 pixels) and peak elevation > 30 m (consistent with CALIPSO nominal vertical accuracy).File: islands information used in SFTH retrieval.csv (UTF-8; lon/lat in decimal degrees).Fields: No., Island Name, Longitude, Latitude, Elevation(m), Area(km2).Source: compiled from Mapcarta (please record access date in the associated paper/metadata).
本数据集收录用于海雾顶高反演的岛屿坐标、面积与峰顶高程信息,以此作为海雾顶高反演的高度参照基准。黄渤海海域的岛屿可提供天然几何约束条件:当雾顶高度高于岛屿峰顶高程时,峰顶会在影像中被淹没;当雾顶高度更低时,峰顶则保持可见,且地形与雾体的相互作用可能产生局部空洞或对比度特征。 筛选标准(中分辨率成像光谱仪MODIS,250米分辨率):面积大于0.25平方千米(至少包含4个像素),且峰顶高程高于30米,该标准与云气溶胶激光雷达与红外探路者卫星观测(CALIPSO)的标称垂直精度要求一致。 数据文件:用于海雾顶高反演的岛屿信息.csv(编码格式为UTF-8;经度、纬度采用十进制度格式)。 数据字段依次为:序号、岛屿名称、经度、纬度、高程(单位:米)、面积(单位:平方千米)。 数据来源:整合自Mapcarta平台,请在相关论文或元数据中记录数据获取日期。
