Dear WRF-Chem/MOZBC Team,

I have been facing repeated issues while trying to download WACCM data for the following request. 

E-mail: 
Full name: 
Affiliation:
Address:
lat2: 27.5
lon1: 74
lon2: 101
lat1: -7
startYear: 2022
startMonth: 01
startDay: 31
endYear: 2022
endMonth: 03
endDay: 01
simulation: waccm

The system returns the message:

There were problems accessing the data:
Error preparing second attempt at ncrcat.
[Errno -101] NetCDF: HDF error: b'/home/drews/CAM-Chem/stage/803463.f.e22.beta02.FWSD.f09_f09_mg17.cesm2_2_beta02.fforecast.001.cam.h3.2022-02-15-00000.nc'
Download request ID: 803463

I have been trying for weeks now, but the download consistently fails, and I am unable to proceed with MOZBC. My work is currently stuck because of this.

Could someone please let me know what can be done?

Thank you very much for your support.

Hello Mariya -

The NSF NCAR supercomputers came back online last night at 7:21 PM Mountain after scheduled maintenance. It looks like the NCAR Research Data Archive (RDA) is still working through the backlog of download requests. I have re-issued your download request and will let you know when it completes.
