NASA TIROS Project

TIROS-2 Medium-Resolution Scanning Radiometer Level 1 Final Meteorological Radiation Data (FMRT) product contains radiances expressed in five infrared/visible wavelength regions, expressed in either equivalent blackbody temperature (IR channels 1 and 2) or effective radiant emmitance (visible channels 3 and 5). The data will trace an elliptical, parabolic, or hyperbolic pattern on the ground due to the rotating of the instrument about the satellite spin axis. There is one orbit per file. The data were originally written on IBM 7094 machines, and these have been recovered from magnetic tapes, r...TIROS-2 中分辨率扫描辐射计（Medium-Resolution Scanning Radiometer）一级最终气象辐射数据（FMRT，Final Meteorological Radiation Data）产品包含覆盖五个红外/可见光波段的辐射亮度数据，其数值可表示为等效黑体温度（对应红外通道1与2）或有效辐射发射率（对应可见通道3与5）。由于仪器围绕卫星自旋轴旋转，该数据在地面会呈现椭圆、抛物线或双曲线的扫描轨迹。每个文件对应一条轨道的数据。该数据最初存储于IBM 7094计算机中，目前已从磁带中恢复...
