[gradsusr] plotting of TRMM 3A12 data with GrADS

[Zhong Liu]

Dear Sabir Sardar,

Thank you for your inquiry about TRMM 3A12.

You need to modify your ctl file. Here is an example in our FAQ,

http://disc.sci.gsfc.nasa.gov/additional/faq/precipitation_faq.shtml#ctl_file

or,

Can I see an example of a GrADS ctl file for TRMM Level-3 HDF data?

The following example of a ctl file may be useful to TRMM data users
familiar with GrADS.

DSET ^3A12.070101.6.HDF

DTYPE hdfsds

TITLE This is only a test UNDEF -9999.9

XDEF 720 LINEAR -179.7500000 0.5000000

YDEF 160 linear -39.7500000 0.5000000

ZDEF 14 LEVELS 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 5.0 6.0 8.0 10.0 14.0 18.0

TDEF 1 LINEAR jan2007 1mo

VARS 8

surfaceRain=>sfcr 1 z,x,y surface rain

convectRain=>convr 1 z,x,y convection rain

stratiformRain=>stratr 1 z,x,y stratiform rain

cldWater=>cldw 14 t,z,x,y cloud water

precipWater=>precipw 14 t,z,x,y precipitable water

cldIce=>cldi 14 t,z,x,y cloud ice

precipIce=>precipi 14 t,z,x,y precipitable ice

latentHeat=>heat 14 t,z,x,y latent heat

ENDVARS

Please let us know if you have further questions.

Regards,

-Zhong
