The surface temperature increase that partially gave rise to concerns about global warming coincided with a move to tethered electronic measuring devices (um, I think that means thermometers) that forced the movement of many stations closer to buildings and developed areas, causing warming that may not have been corrected for.

Aqua's suite of instruments include devices that will measure cloud properties, the wetness of land surfaces, land and sea temperatures, humidity and temperature at different levels of the atmosphere, the properties of particles in the air, fluctuations in solar energy absorption and many other parameters.

Every measuring device used is really only estimating a guess as to what the true temperature of the true substance you are measuring is and it can never be correct because of the errors present in all measuring devices, the errors present in defining the substance being measured, and measuring that, and the the time lapse which means that what you were measuring was changing while you measured it and can not be proven correct then, now or in the future.

If there is an offset (i.e., one device measures a slightly different temperature to the other, when they should be the same) then you should correct for that offset.

I would also invite you to think about how perfect LTE could possibly be observed if it did exist; any device you use to measure the thermal radiation or the distribution of velocities or the population of excited states must itself be at a different effective temperature from the gas in question, and must absorb energy from it, disturbing the very equilibrium you are trying to observe.
