According To NASA

According to NASA surface measurements and satellite measurements of Earth's temperature do not match:

Unlike the surface-based temperatures, global temperature measurements of the Earth's lower atmosphere obtained from satellites reveal no definitive warming trend over the past two decades. The slight trend that is in the data actually appears to be downward. The largest fluctuations in the satellite temperature data are not from any man-made activity, but from natural phenomena such as large volcanic eruptions from Mt. Pinatubo, and from El Niño. So the programs which model global warming in a computer say the temperature of the Earth's lower atmosphere should be going up markedly, but actual measurements of the temperature of the lower atmosphere reveal no such pronounced activity.
I wonder why?

That NASA article's 10 years old - is there more recent data on satellite-measured lower atmosphere temperature trends?

Since the most recent re-adjustment the match is better.

Latest estimates from the satellites and ground show temperature decline from almost no decline to slight cooling.
