How is a surface-based partial obscuration covering 3/8 of the sky encoded in column 10?

For a surface-based partial obscuration that covers 3/8 of the sky, the correct encoding in column 10 is represented by "SCT000." The term "SCT" stands for "scattered," which is used to describe cloud coverage that is between 1/8 and 4/8 of the sky covered. In this case, since 3/8 falls within that range, "SCT" is the appropriate descriptor.

The numbers that follow "SCT" indicate the base altitude of the clouds in hundreds of feet above ground level. In this case, "000" signifies that there are no clouds below 1,000 feet, suggesting clear conditions at lower altitudes. Thus, the information effectively communicates both the degree of cloud cover and the altitude, reflecting a partial obscuration of the sky.
