What about the resolution of the land based stations?

The accuracy of the maximum-minimum temperature system (MMTS) is +/- 0.5 degrees C, and the temperature is displayed to the nearest 0.1 degree F.
The former is the accuracy of the measurement system as a whole and the latter is the precision of the measurement devices. I would not expect someone of your shallow knowledge of science to grasp how this works, but here is a link that may help you.

The Maximum Minimum Temperature Sensor used in the majority of land based stations has a margin of error of a full degree C. Once that is taken into consideration the only conclusion one could logically arrive at is complete skepticism about the OP study.
No, since the current accuracy is greater than it was in the past, the error margins are lower and as such does not affect the study.

For the record NOAA is trying to field some new wireless stations to combat poor placement problems.

The bad news is it doesn't appear the censor technology has been improved so we're still looking at a margin of error of plus or minus .5 degree C.

Temperature Accuracy Typical: ±1°C (±2°F)
Still this will not improve future land based studies and does not save a poor OP study for this thread.
Only because you know nothing of which you speak, but that is more and more commonly known.
