Hi Jack,
re:
> ...CONUS 190.5 km grid (grid 202). ... the data ... is shifted to the south
> relative to output on the other grids available
> GFS201: Mean sea level pressure on grid 201 (NH polar stereographic, grid spacing 381 km)
> GFS202: Mean sea level pressure on grid 202 (CONUS polar stereographic, grid spacing 190.5 km)
> GFS213: Mean sea level pressure on grid 213 (CONUS polar stereographic, grid spacing 95.25 km)
I ran a number of inter-comparisons between different projections and models for P at MSL
for the same model run time and forecast hour. It seems clear that the 202 grid plot looks
shifted southward in all tests I ran on Saturday, day 2008068.
My first guess is that the calculation of the row number of the pole is off. I will be
looking through the code to see I can see anything obviously wrong.
More later...
Cheers,
Tom
