Ground temperature measures air temperate at 1.5 meters. Lower troposphere measures the average from 0 meters to 10 km, weighted heavily toward the lower 4 km. It's not exactly intuitive why ground temperature and lower troposphere temperature should be different, but in short, during wet seasons, troposphere will be relatively warmer, and during dry seasons, ground will be relatively warmer. I think ground is what we care about here, though, as that most directly impacts human wellbeing.
