Plotting Table File: g_plots.tbl

This table is used to define times, levels and fields to be processed and plotted by Graph. An example is shown below:

TIME LEVELS: FROM 1993-03-13_00:00:00 TO 1993-03-14_00:00:00 BY 21600 (A)
PRESSURE LEVEL MANDATORY: FROM SFC TO PTOP (B)
PRESSURE LEVEL NON STANDARD: FROM SFC TO PTOP BY 3 (C)
SIGMA LEVEL: FROM 23 TO KMAX BY 5 (D)
TITLE: MM5 Tutorial (E)

Description of Table Header Rows:
 

(A)

TIME

with beginning and ending times given in YYYY-MM-DD_HH:MM:SS, and time increment given in seconds defined by the number after BY. If one doesn't use :SS, the increment should be in minutes, and if one doesn't use :MM, then the increment should be in hours. `BY 0' means to plot every output times.

(B)

MANDATORY

used for pressure level dataset (such as from DATAGRID and Rawins). Will plot every mandatory level from the maximum and minimum level requested. ALL and NONE may also used to replace the entire string after the colon.

(C)

NON STANDARD

used for pressure level dataset. Will plot every mandatory level from the maximum and minimum level requested. Optional use of BY n will make plots at every n levels. ALL and NONE may also be used to replace the entire string after the colon. 

(D)

SIGMA

used for ?-level data. Will plot the levels specified by indexes (K=1 is at the top of the model). An increment is required, and defined by the number after BY. Can also use ALL or NONE.

(E) 

TITLE

except for a colon (:), any alpha-numeric character can be used to make a simple 1 line, 80 character title

Description of Table Columns:

PLOT

T/F

True or False to plot this field. Removing the line from the table has the same effect as F. If the user requests a cross section plot, the letter is X. If the user requests a plot on pressure level, the first 2 characters are TP, followed by the pressure value (TP500 is 500 mb level); if the user requests a plot on isentropic surface, the first 2 characters are TI, followed by the potential temperature value (TI330 is 330 K level). The last two options only work with ? data.

FIELD

a field name to be plotted. See complete list in Tables 8.1, 8.2 and 8.3. If the field is a skew-T, the interpretation of the following columns is changed (see the explanation below).

UNITS

units used on a plot. For some fields, there are different standard units available. If you don't know the unit, use `?'.

CONTOUR
INTERVAL

real or integer values used to contour a plot. If you don't know what contour interval to use, use `0'. For a vector field (e.g. BARB), this value specifies the grid interval. For streamline field (VESL), this value specifies how sparse or dense streamlines are drawn.

SMOOTH
PASSES

number of passes of the smoother-desmoother used for each horizontal plot.

OVERLAY
FIELD

a field name for the overlay plot. May be left blank.


If the plot is a skew-T (SKEWTLL or SKEWTXY), the UNITS column is used to define location name, and lat/long or X/Y appear in the following two columns.

For a cross-section plot, the location is defined by the 4 numbers in the columns following `X', and they are in the order of X1, Y1, X2, and Y2.
