The 1990 IPCC report showed US daily maximum temperatures plummeting at 1.3C per century since 1930.
The report also showed US daily minimum temperatures flat since 1930.
From this, they should have been able to approximate how much UHI was occurring, by subtracting the maximum temperature anomaly from the minimum temperature anomaly. This is because UHI primarily affects minimum temperatures. Had they done this they would have seen that UHI is causing a 1.2C/century increase in nighttime temperatures.
But instead of doing the right thing and adjusting recent nighttime temperatures downwards (thus ending their global warming scam) they came up with a set of adjustments which cool older temperatures, and warm recent temperatures.

GYG!!!!!!!!!!!!!!!!!
You absolutely have to increase recent temperatures and cool the past or there would be an upsetting downward trend in World temperature. All over the Earth Climate Scientists are working in concert to ensure that their pay and grants keep on rolling in, as long as the temperature never goes down. It has been a challenge over the past seventeen years but their efforts have been immense and they are rewarded. You know that it makes sense.
