Set up GSI Global Analysis

[Back to the Index]

Introduction

This exercise consists of running the GSI 3D hybrid analysis with T254 global (GFS) background field, conventional data from prepbufr, satellite radiances and gpsro data.

Background and Data

The background files are:
          
  • surface gfs forecast files at 3 time levels: 3, 6, 9 hours
  • sfcf03 sfcf06 sfcf09
  • atmosphere gfs forecast files at 3 time levels: 3, 6, 9 hours
  • sigf03 sigf06 sigf09
    The observation files are:
    	prepbufr   (conventional data)
    	airsbufr   (gdas1.t06z.airsev.tm00.bufr_d) 
    	gomebufr   (gdas1.t06z.gome.tm00.bufr_d)
    	gsnd1bufr  (gdas1.t06z.goesfv.tm00.bufr_d)
    	iasibufr   (gdas1.t06z.mtiasi.tm00.bufr_d)
    	sbuvbufr   (gdas1.t06z.osbuv8.tm00.bufr_d)
    	ssmisbufr  (gdas1.t06z.spssmi.tm00.bufr_d)

    	gpsrobufr  (gdas1.t06z.gpsro.tm00.bufr_d)
    	hirs4bufr  (gdas1.t06z.1bhrs4.tm00.bufr_d)
    	mhsbufr    (gdas1.t06z.1bmhs.tm00.bufr_d)
    	satwndbufr (gdas1.t06z.satwnd.tm00.bufr_d)
    	seviribufr (gdas1.t06z.sevcsr.tm00.bufr_d)
    	tmirrbufr  (gdas1.t06z.sptrmm.tm00.bufr_d)
