Hourly Surface Solar Irradiance (netCDF) - GOES

Estimation of the hourly solar irradiance reaching the Earth surface derived from the 0.6 µm visible channel of the imager on board the geostationary satellite GOES. Algorithm is a physical parametrization applied separately to every pixel of a satellite image to derive an instantaneous field of the Solar Surface Irradiance. The product is interpolated at rounded UT hours, by a pixel dependant temporal interpolation between two consecutive satellite images. It is remapped onto a 0.05° regular grid and expressed in W/m2.

本数据集针对到达地球表面的逐小时太阳辐照度进行估算，该估算结果由地球静止卫星GOES搭载的成像仪的0.6微米可见光通道反演得到。算法采用物理参数化方案，对卫星影像的每个像素独立执行处理，以反演得到瞬时地表太阳辐照度场。本产品通过对两幅连续卫星影像进行逐像素时间插值，将结果插值至取整的世界时整点时刻，随后被重采样至0.05°的规则网格，单位为W/m²。
