Dear,
I have a problem in the data I'm working on, GFS (timetables data).
The variables I'm working on are: u, v, q (1000-300 hPa) and psl (all 00 and 12h).
The input data in my program MUST be daily.
So did the average for each variable of the two time (00 and 12h).
The file it opens normal pressure levels are just right, but the information in aquivo "ctlinfo" shows the following:
dset Final_20150104_vars.nc
NCL title: convert-to-GRIB-netCDF
undef 1e + 20
dtype netcdf
xdef 37 straight 309 0.5
ydef 43 linear -20 0.5
ZDEF 17 levels 1000 975 950 925 900 850 800 750
700 650 600 550 500 450 400 350 300
tdef 1 linear 06Z04JAN2015 1mn
vars 4
RH_P0_L100_GLL0 => 17 rh_p0_l100_gll0 t, z, y, x Relative humidity
TMP_P0_L100_GLL0 => 17 tmp_p0_l100_gll t, z, y, x Temperature
UGRD_P0_L100_GLL0 => 17 ugrd_p0_l100_gl t, z, y, x u-component of wind
VGRD_P0_L100_GLL0 => 17 vgrd_p0_l100_gl t, z, y, x component of wind V-
endvars
See, that in "tdef" time is "mn" and not "dy" as you like.
The average did with CDO (Climate Data Operators).
Does anyone have suggestions for resolving it?
Thanks,
May.

Prezados,
Estou com um problema nos dados que estou trabalhando, o GFS (dados horários).
As variaveis que estou trabalhando são: u, v, q (1000 a 300 hPa) e psl (todos de 00 e 12h).
Os dados de entrada em meu programa PRECISA ser diário.
Logo, fiz a média para cada variável dos dois tempos (00 e 12h).
O arquivo ele abre normal, os níveis de pressão estão certinho, mas nas informações do aquivo no "ctlinfo" mostra o seguinte:
dset Final_20150104_vars.nc
title NCL: convert-GRIB-to-netCDF
undef 1e+20
dtype netcdf
xdef 37 linear 309 0.5
ydef 43 linear -20 0.5
zdef 17 levels 1000 975 950 925 900 850 800 750
700 650 600 550 500 450 400 350 300
tdef 1 linear 06Z04JAN2015 1mn
vars 4
RH_P0_L100_GLL0=>rh_p0_l100_gll0 17 t,z,y,x Relative humidity
TMP_P0_L100_GLL0=>tmp_p0_l100_gll 17 t,z,y,x Temperature
UGRD_P0_L100_GLL0=>ugrd_p0_l100_gl 17 t,z,y,x U-component of wind
VGRD_P0_L100_GLL0=>vgrd_p0_l100_gl 17 t,z,y,x V-component of wind
endvars
Veja, que em "tdef" o tempo está em "mn" e não "dy" como gostaria.
As médias fiz com o cdo (Climate Data Operators).
Alguém tem sugestão para resolver isso?
Obrigada,
May.
