Notes:

[1] All multiple-level fields interpolated to standard pressure levels (1000, 925, 850, 700, 600, 500, 400, 300, 250, 200, 150, 100, 70, 50, 30, 20, 10 hPa).
[2] CLOUD is left on original CCSM CAM3 hybrid sigma-pressure levels.
[3] "tasmax" is maximum reference height temperature over the month.
[4] "tasmin" is minimum reference height temperature over the month.
