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:

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:
