Error occurred when I use ECMWF archived forecast data to run WRF

[z2liao]

Hello everyone,

I'm encountering issues while attempting to run the Weather Research and Forecasting (WRF) model using ECMWF forecast data. Previously, I successfully ran WRF using GFS data without any problems, but this new situation has presented some challenges.

Issue with Pressure Level (PL) Data: While processing the PL part, I first link the PL files and then modify the namelist.wps to prefix = '3D'. However, I encounter an error stating, "Unknown Data Representation Type, ksec2(4)= 50". Upon investigation, I found that ksec2(4) relates to a grid type, which seems valid only for values 0-5. I'm unsure how to resolve this issue.

./link_grib.csh /public3/home/scb9701/ecdata/ECMWF_PL*
edit namelist.wps: prefix = '3D',
./ungrib.exe




Issue with Surface (SFC) Data: For the SFC part, I'm facing a different error: "ERROR: Grib2 file or date problem, stopping in edition num." This confuses me because my input file is in GRIB format, not GRIB2.

./link_grib.csh /public3/home/scb9701/ecdata/ECMWF_SFC*
edit namelist.wps: prefix = 'SFC',
运行ungrib: ./ungrib.exe


Could anyone with experience in handling ECMWF data in WRF provide some guidance or suggestions on how to fix these two problems? Any help or insights would be greatly appreciated.


Thank you in advance!

where did you download the ECMWF forecast data? The error messages are more related to Vtable, which may not be working for your data.

Thank you for your reply. I downloaded EC data directly from ECMWF official website (requested MARS licence)
