Ground stations measure conditions at individual locations. Weather balloons and aircraft provide information from different altitudes.
Each source has its own resolution, update frequency, coverage gaps and measurement errors. Building the current state of the atmosphere is therefore like reconstructing traffic across an entire city using cameras that point in different...
