|Layer to map:
1 = SLP, 2 = Height at pressure level (select level),
3 = 2-meter Temp, 4 = Temp at pressure level (select level),
5 = U-wind component (select level), 6 = V-wind component (select level),
7 = Skin Temp, 8 = Precipitable Water, 9 = Relative Humidity (select level up to 300 mb),
10 = ERSST v.4 SSTs (Slow, through Oct 2016: 2.5 minutes), 11 = Wind Speed (select level),
12 = U-wind Shear (select levels), 13 = Height Thickness (select levels),
14 = Temperature Between Pressure Levels, 15 = Potential Velocity (0.2101 sigma),
16 = NASA Global Temps (VERY SLOW!: Through Oct 2016), 17 = Specific Humidity, 18 = Tropical Cyclone Formation Combined [Temporarily Disabled]
Choose Theme (1-17):
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:
|Bounding Coords for Rank Computation
This computes a single, rank value for the selected
time period. It does not affect the map. Remember that
longitude runs from 0 to 360 (no E-W). These values do not
affect the area to be mapped (see bottom of page).

|Last month to start evaluation (e.g., 2 for Feb):
||Number of months (up to 12) to evaluate (e.g., 3 for Dec-Feb):
||Year of last month to start evaluation:
||Map Type: 1=Cyclindrical, 2=North Pole (NH Only), 3=Lambert Equal Area (Best for High Lats),
|Manually Enter Map Bounds: 0=No, 1=Yes
Note 1: Coords only used if map type is Cylindrical (1) or Lambert Equal Area (3).
Note 2: If Using Lambert Equal Area, make sure longitude spread is <= 50° in mid-latitudes.
