Reject radiance data while assimilating

Reject radiance data while assimilating

Postby REKHA BHARALI GOGOI » Wed Nov 10, 2010 7:33 am

Hi Everyone,

While running WRFDA I am facing some problem regarding radiance data assimilation. When I use AMSUA/AMSUB/HIRS3 data, there is no problem at all. But whenever I use any data such as HIRS4, MHS from NOAA-18, EOS-2 or METOP-2, it used to reject all the data. I dont know what is the matter behind this. Is it an error or all the data are outside my domain? I am very confused.

Some part of the log file is given below:

Reading radiance 1b data from amsub.bufr
Bufr file date is 2010 4 22 0
amsub.bufr
num_tovs_file num_tovs_global num_tovs_local num_tovs_used num_tovs_thinned

Pliz help me out.

I would suggest checking if you do have data from these sensors over your domain.

Hi ,do you have met the errors like as following?

**************BUFR ARCHIVE LIBRARY ABORT*****************
BUFRLIB: OPENBF - ERROR READING INPUT FILE CONNECTED TO UNIT 26 WHEN CHECKING FOR 'BUFR' IN FIRST 4 BYTES OF RECORD
**************BUFR ARCHIVE LIBRARY ABORT*****************

I use pgi compiler to run radiance testcase on Linux with wrfda 3.2 and crtm 1.2, the WRFDA website said there have some tips to solve the problems, but it says it is only take effect on GFORTRAN and IFORT compiler while without anything about PGI compiler. So I want to ask you for some help, can you give me some hints? Thank you very much.

I do not use pgf compiler, hence unable to help you on this.

Thank you for your reply...as you told I have checked and found that the sensor does not cover my domain...
