GFS forecast 2-m fields


New member
Hello all, I downloaded the GFS forecasts data for the use in WPS/WRF which are available here:
Index of /pub/data/nccf/com/gfs/prod/gfs.20240630/12/atmos

I checked the index files of the GFS forecast that I downloaded and I see that the 2-m temperature and 2-m humidity fields are indeed there:

However, when I process this data through WPS, met_em* do not contain the 2-m temperature and 2-m humidity fields, I only see the 3-D TT and RH fields. So my question is, where did those 2-m data go?

I checked the Vtable.GFS and noticed that the same variable name TT is used both for 3-D temperature field as well as the 2-m temperature field (see below). Could it be due to this? Can anyone explain this please and tell how to fix this?

GRIB1| Level| From | To | metgrid | metgrid | metgrid |GRIB2|GRIB2|GRIB2|GRIB2|
Param| Type |Level1|Level2| Name | Units | Description |Discp|Catgy|Param|Level|
11 | 100 | * | | TT | K | Temperature | 0 | 0 | 0 | 100 |

11 | 105 | 2 | | TT | K | Temperature at 2 m | 0 | 0 | 0 | 103 |

Appreciate your insights.
This is not a Vtable issue. I also don't think there is anything wrong with ungrib.
I am suspicious that you didn't download the file that contains 2-m T. Please double check the GFS data you downloaded.
