>Here is basically how their approach works. For each center point in a global grid of 1-degree boxes they let all weather station data within a 1,200 kilometer radius influence the estimated temperature change at that point.
1) What is the center point?
2) "global grid" is....?
3) 1-degree boxes....are boxes meteorological equipments?
For your reference, this follows after the above sentence.
>They gave greatest "weight" to the station closest to that point; for all other stations within that radius, they let the weighting fall off linearly with distance, all the way to a weighting of zero for stations 1,200 kilometers away or farther.
I would apprecaite it if some of you put the sentence in another way. Thanks.
