Keywords

DAY=	Julian day, YYDDD (default=current)
FORM=	STD	lists a brief description of the grids; see the Remarks (default)
	ALL	lists detailed information about the grids; see the Remarks
GRIDF=	grid file numbers to check (default=lists all real-time grid files for the specified day)
MOD=	ALL	searches all model types (default)
	m1 . . mn	searches for one or more specific models, valid options are:
	GFS	Global Forecast System model grids
	NAM	North American Mesoscale model grids
	NGM	Nested Grid Model grids
TIME=	ALL	searches all run times (default)
	t1 . . tn	searches the specified range of run times, H, HH:MM or HH:MM:SS

Remarks

NMCAMT lists both complete and partial real-time grids. A partial grid contains incomplete grid sections. Currently, the GFS model is the only model transmitted in pieces; thus, it is the only model containing partial grids.

Note: The NGM options are still valid in this command even though the NWS terminated the NGM model and its associated products beginning 03 March 2009 (NWS TIN08-90).

The FORM=STD option provides the following information:

grid file number
grid number
parameter
level
run time
forecast time
model name of partial grids

The screen below shows an example of the FORM=STD output.

The projection of an GFS grid determines how it is sent. Grids that are 145 rows by 289 columns are sent in the following eight sectors:

Sector	Latitude range	Longitude range
1	0°N-90°N	60°E-30W
2	0°N-90°N	150°E-60°E
3	0°N-90°N	120°W-150°E
4	0°N-90°N	30°W-120°W
5	0°S-90°S	60°E-30°W
6	0°S-90°S	150°E-60°E
7	0°S-90°S	120°W-150°E
8	0°S-90°S	30°W-120°W

Grids that are 73 rows by 73 columns are sent in the following four sectors:

Sector	Latitude range	Longitude range
1	0°N-90°N	180°E-0°E
2	0°N-90°N	0°W-180°W
3	0°S-90°S	180°E-0°E
4	0°S-90°S	0°W-180°W

If a grid is missing a section, the FORM=ALL option marks the missing section with an asterisk (*). In the example below, grid 257 in grid file 5109 is missing the fourth section. The Xs indicate that sectors 1-3 and 5-8 were received.

The FORM=ALL option provides the following additional information:

byte location of the message in the spool file
the number of rows and columns of the grid
the time the grid was received

Examples
