@openscience Of course they use the UAH dataset. They always do.

- TLT is *calculated* based on satellite data from other sources. It's not measurements.
- the UAH dataset uses a different method for this calculation than all other satellite based datasets.
- UAH also uses a different correction for drift of measurements than NASA, and the UAH "correction" removes part of the trend.
- the UAH differs significantly from the other big datasets.
