Pressure Level: 0 = 1000mb, 1 = 925mb, 2 = 850mb, 3 = 700mb, 4 = 600mb, 5 = 500mb, 6 = 400mb, 7 = 300mb, 8 = 250mb, 9 = 200mb, 10 = 150mb, 11 = 100mb, 12 = 70mb, 13 = 50mb, 14 = 30mb, 15 = 20mb, 16 = 10mb

Note 1: use lower pressure level 0 for surface themes - layers 1, 3, 7, 8, and 10.
Note 2: use only lower pressure level for themes 2, 4, 5, 6, 9, and 11.
Note 3: use lower and upper pressure levels for themes 12, 13, and 14.

Lower pressure level:       Upper pressure level:

If you change the start date, it changes the start date for ranking maps too.
End date change does not affect end date for rankings.

The program takes 1-2 minutes to run. If two levels are used, count on 2 minutes.
For NASA GISS temps, 2.5 minutes (1 month) to 10 minutes (12 months).
