da_wrfvar.exe error (SYNDAT and VADWND of PREPBUFR)

[kura]

Hello,

I downloaded the PREPBUFR data for 2023-08-02 from the following site:

Loading…

data.rda.ucar.edu

Using prepbufr2littleR.exe, I converted the PREPBUFR data into the Little_R format, which resulted in the creation of the following 9 files:

mssg_type	mssg_num	subset_num
ADPUPA	415	1263
AIRCFT	35	3706
SATWND	1721	230147
VADWND	2070	4185
ADPSFC	1542	164010
SFCSHP	439	56731
RASSDA	14	210
ASCATW	737	119258
SYNDAT	1	60

Software Versions:

• WRF/WRFDA: 4.6.0
• WPS: 4.6.0

When I ran da_wrfvar.exe, errors occurred with the following two types of files:

• SYNDAT <- attached
• VADWND

No errors occurred with the other files.

The error message is as follows:
---
taskid: 0 hostname: micro01

Fortran runtime error: Bad value during floating point read
