The NAM model contains forecast data every 3 hours from forecast
hours 0 to 48 on a 12 km 614 x 428 grid covering the United States
and Southern Canada. Domain map of NAM 12 km.
The NAM model contains forecast data every 3 hours from forecast
hours 0 to 84 on a 40 km 185 x 129 grid covering the United States
and Southern Canada. Domain map of NAM 40 km.
The NAM model contains forecast data every 3 hours from forecast
hours 0 to 36 on a 45 km 139 x 107 grid covering northwestern North America
and eastern Russia. Domain map of NAM Alaska.
The RUC model contains forecast data every hour from forecast
hours 0 to 12 on a 20 km 301 x 225 grid covering the United States
and Southern Canada. Domain map for RUC 20 km.
The Global Forecasting System or GFS (formerly called the Aviation Model) contains forecast data every 3
hours from forecast hours 0 to 84 on a 1 degree latitude/longitude grid covering the globe. In addition,
we map this data to northern and southern hemispheric 257 x 257 grids for use by programs other than HYSPLIT.
The model data is updated 4 times per day. Northern hemisphere domain map.Southern hemisphere domain map.
The Global Forecasting System or GFSx (we denote this longer forecast GFS dataset with an x) contains
forecast data every 6 hours from forecast hours 0 to 180 on a 1 degree latitude/longitude grid covering
the globe. In addition, we map this data to northern and southern hemispheric 257 x 257 grids for use
by programs other than HYSPLIT. The model data is updated 4 times per day.

The Global Forecasting System or GFSlr (we denote this very long forecast GFS dataset with lr) contains
forecast data every 12 hours from forecast hours 192 to 384 on a 2.5 degree latitude/longitude grid
covering the globe. In addition, we map this data to northern and southern hemispheric 129 x 129 grids
for use by programs other than HYSPLIT. The model data is updated 4 times per day.
