[wrfems] question on ice cover datasets

[Case, Jonathan (MSFC-VP61)[Other]]

As a follow-on,

I looked at the gribinfo files in my EMS v311beta, and it appears that all 3 datasets are "ice5min" according to the file-naming conventions.  This is contrary to the naming conventions that Robert Grumbine alluded to in my email exchanges with him.

Robert pointed me to the following operational server/files in his email to me:

"The operational server (24x7 support) location is

ftp://ftpprd.ncep.noaa.gov/pub/data/nccf/com/omb/prod/sice.YYYYMMDD/engice.t00z.grb.grib2

where YYYYMMDD is the year, month, day."

Subject: [wrfems] question on ice cover datasets

Dear WRF EMS Users,

This question is most likely directed to BobR, but I wanted to post it to the group in case anyone else wondered about the ice cover databases in the EMS.

When I do a "ems_prep --dslist" , I receive the following surface options for ice cover:
     ice5min : NCEP 0.083 (1/12th) degree global high res ice cover - FOR USE WITH THE --sfc OPTION ONLY
     iceptile  : NCEP 0.083 (1/12th) degree global high res ice coverage personal tile  - FOR USE WITH THE --sfc OPTION ONLY
     seaice    : NCEP 0.083 (1/12th) degree global high res ice cover - FOR USE WITH THE --sfc OPTION ONLY

For clarification purposes, should the description of the ice5min be different?  It reads as if it's the same as the 0.083 degree dataset, but I figure it must be different, given that it is a different option.   Which dataset is the highest resolution and which one is the one developed by Robert Grumbine at NCEP?

Thanks a lot!
Jonathan
