Subject:  Soliciting Public Comments Through March 31, 2012,
          for Experimental Ensemble Kernel Density Model
          Output Statistics (EKDMOS) Products

The NWS is soliciting public comments by March 31, 2012, on 
experimental EKDMOS guidance products for the CONUS and Alaska. 
These products are available in GRIB2 format. EKDMOS uses output 
from the North American Ensemble Forecast System (NAEFS) to 
produce probability distributions of sensible weather elements. 
The EKDMOS CONUS (Alaska) products contain guidance on a 2.5 km 
Lambert Conformal (3.0 km Polar Stereographic) grid. These grids 
cover the same expanse as the corresponding National Digital 
Forecast Database (NDFD) grids. Grids will be generated twice 
daily, based on the 0000 and 1200 UTC runs of the NAEFS. To 
express the probability distribution, grids will be produced for 
the ensemble mean and for these 11 non-exceedance probability 
levels:

     .05, .10, .20, .30, .40, .50, .60, .70, .80, .90, and .95

The following surface weather elements and time projections will 
be available initially:

     - 2-m temperature guidance every 3 hours for days 1 to 8,
       then every 6 hours for days 8 to 10 for the ensemble
       mean and 11 non-exceedance probability levels.
     - 2-m dewpoint guidance every 3 hours for days 1 to 8,
       then every 6 hours for days 8 to 10 for the ensemble
       mean and 11  non-exceedance probability levels.
     - Daytime maximum temperature guidance for days 1 to 14
       for the ensemble mean and 11 non-exceedance probability
       levels.
     - Nighttime minimum temperature guidance for days 1 to 14
       for the ensemble mean and 11 non-exceedance probability
       levels.

Additional weather elements will be added in the future.

directory and file structure can be found online at:

products by using the brief survey and comment form available on
