SHARAD Surface Reflectivity Data for McGlasson et al. (submitted to JGR Planets)

SHARAD surface reflectivity maps for Martian PLDs and outlying crater deposits. <br> Both reflectivity maps are in equicylindrical projection using the Mars 2000 geographic coordinate system (GCS_Mars_2000_Sphere, 3396190.0 radius). Data covers poleward of 60 degrees in each hemisphere, and areas outside of the outlying deposits and PLDs are set to NoData. <br> Data are 20 ppd resolution, 64 bit pixel format. NoData pixels are represented by a value of -9999. Units are in meters. <br> <br>

针对火星极地层状沉积区（PLDs）及周边陨石坑沉积体的SHARAD表面反射率图。
两幅反射率图均采用等圆柱投影，基于火星2000地理坐标系（GCS_Mars_2000_Sphere，半径3396190.0米）构建。数据覆盖南北半球60度纬度极地方向区域，而周边沉积体与PLDs之外的区域被设为无数据（NoData）值。
数据分辨率为20像素/度（ppd），采用64位像素格式。无数据像素以数值-9999表示，单位为米。
