GOES-16 MCMIPC 系列 ABI 2 级云层和水汽成像 CONUS数据

​

GOES-16 MCMIPC 系列 ABI 2 级云层和水汽成像 CONUS

简介

云层和水分成像产品的分辨率均为 2 公里。 1-6 波段为反射波段。 无量纲的 "反射系数 "以太阳天顶角为标准。 这些波段有助于确定云、植被、雪/冰和气溶胶的特征。 第 7-16 波段为发射波段。 大气顶部 (TOA) 的亮度温度以开尔文为单位测量。 这些波段支持根据发射特性对地表、云层、水蒸气、臭氧、火山灰和尘埃进行定性。 README NOAA 的卫星和产品运行办公室有一个提供状态更新的 "一般卫星信息 "频道。
