UPPV2.2 southern hemisphere projection

Postby andrew.wiebe » Thu Feb 05, 2015 7:59 pm

Hi All,

I am trying to use UPPV2.2 to post process WRF3.5-ARW output for Australia.
Unipost runs successfully but when I view the output in IDV5.0u2 the map is offset by ten degrees or more ( i'd attach an image but the system won't let me.)
I have looked at the metadata in the grib file and the start/end lat/lon are correct

center 7 subcenter 0 process 125 Table 2 scan: WE:SN winds(grid)
Mercator: lat -44.530000 to -6.942000 by 12.000000 km nxny 164256
long 104.749000 to 160.989000 by 12.000000 km, (464 x 354) scan 64 mode 136 Latin 38.490000 bdsgrid 1

but the image is still offset for some reason.
I converted the grib file to netcdf using ncl_convet2nc and this was projected properly in IDV but most of the variables were missing.

Any suggestions?

It seems to be working OK for me with a mercator projection in South America WRFV3.6.1 and UPPV2.2. Lambert will not work.
Problems with the southern hemisphere have been around for quite a long time: viewtopic.php?f=53&t=346
