Many biases related to, for example, spacecraft altitude, east - west orbital drift, solar heating, and instrument malfunctions.
While there is still some uncertainty regarding how to best correct for issues like orbital drift and transitions to different satellites, satellite - based records now fairly closely mirror surface - based records, though with slightly lower trends.
The sensors also deteriorate over time, and corrections are necessary for orbital drift and decay.
In particular, sattelites are subject to some orbital drift and changes in altitude and sensor function over time that must be corrected, perhaps imperfectly to date.
All use the same underlying satellite readings, but apply different adjustments and models to account for satellite transitions and orbital drift.
