[Wrf-users] Satellite derived wind data in little_r format

Fri Aug 29 22:50:57 MDT 2014

HI All,

How do I write the satellite derived wind data from CIMMS archive in little
r format?
Should the format be similar to the sounding data or surface data?
here's a sample of the data..
when I run the observation nudging option in WRF, it says:
"n=unknow obseravation of sattelite."

is there a specific way of writing this?to little_r?
